+Extracting Data
+===============
+
+Oftentimes you will want to export data from yt to plot in another plotting
+package, or to compare against another set of data elsewhere.  (Although, note
+should be made that ever effort has been made to make yt into a
+publication-quality plotter.)
+
+Data objects all have the :meth:`write_out` method, which accepts a field
+list and a filename.  This will dump to text.
+
+However, if you have `PyTables <http://www.pytables.org/>`_ installed, you can
+also export things in a different way: ::
+
+   >>> cube = pf.h.smoothed_covering_grid(3, left_edge=[0.0,0.0,0.0],
+   ...                                       right_edge=[1.0,1.0,1.0],
+   ...                                       dims=[512,512,512],
+   ...                                       fields=["Density"])
+   >>> f = tables.openFile("my_cube.h5","w")
+   >>> f.createArray("/","my_cube_density", cube["Density"])
+   >>> f.close()
+
+This will generate an HDF5 file with the "Density" array from our smoothed cube
+at the root node, and called "my_cube_density".  With PyTables you can nest
+these, set attributes, and access the data through any application that can
+read HDF5.

+Making Simple Plots
+===================
+
+Single Width Plots
+------------------
+
+Making plots can be considered one of the simplest things to do in yt, and at
+its most primitive you can simply declare which plots to make.
+
+The following recipe opens the parameter file, creates a 'collection' of plots,
+adds a few slices, and then saves it at a fixed width.
+
+.. code-block:: python
+
+   pf = lagos.EnzoStaticOutput("my_data/my_data0001")
+   pc = raven.PlotCollection(pf)
+   pc.add_slice("Density",0)
+   pc.add_slice("Density",1)
+   pc.add_slice("Density",2)
+   pc.set_width(100.0,'kpc')
+   pc.save("my_data0001_100kpc")
+
+Multiple Fields Single Width
+----------------------------
+
+The 'save' command encodes the name of the field into the filename.  It is more
+efficient to 'switch' a field than to add a new slice with a different field.
+
+.. code-block:: python
+
+   fields = ["Density", "Temperature", "x-velocity"]
+   pf = lagos.EnzoStaticOutput("my_data/my_data0001")
+   pc = raven.PlotCollection(pf)
+   pc.add_slice(fields[0],0)
+   pc.add_slice(fields[0],1)
+   pc.add_slice(fields[0],2)
+   pc.set_width(100.0,'kpc')
+   for field in fields:
+       pc.switch_field(field)
+       pc.save("my_data0001_100kpc")
+
+Single Field Multiple Widths
+----------------------------
+
+We can zoom in on our slice very easily, and we can define it to do that and
+vary units, too, thus ensuring we have a consistent set of plots.
+
+.. note::
+   We do some fancy footwork here with the creation of *my_pairs* but it is an
+   idiom that can be applied elsewhere.
+
+.. code-block:: python
+
+   widths = [1000.0, 100.0, 10.0, 1.0]
+   units = ['mpc','kpc','pc','au']
+   my_pairs = [ (w,u) for u in units for w in widths ]
+
+   pf = lagos.EnzoStaticOutput("my_data/my_data0001")
+   pc = raven.PlotCollection(pf)
+   pc.add_slice("Density",0)
+   pc.add_slice("Density",1)
+   pc.add_slice("Density",2)
+   for w, u in my_pairs:
+        pc.set_width(w,u)
+        pc.save("my_data0001_%05i%s" % (w, u))
+
+Multiple Fields Multiple Widths
+-------------------------------
+
+Because of the way the slices are created and the fields handled, we set our
+outer loop to be over the field and the inner loop to be over the widths.
+
+.. code-block:: python
+
+   fields = ["Density", "Temperature", "x-velocity"]
+   widths = [1000.0, 100.0, 10.0, 1.0]
+   units = ['mpc','kpc','pc','au']
+   my_pairs = [ (w,u) for u in units for w in widths ]
+
+   pf = lagos.EnzoStaticOutput("my_data/my_data0001")
+   pc = raven.PlotCollection(pf)
+   pc.add_slice(fields[0],0)
+   pc.add_slice(fields[0],1)
+   pc.add_slice(fields[0],2)
+   for field in fields:
+       pc.switch_field(field)
+       for w, u in my_pairs:
+            pc.set_width(w,u)
+            pc.save("my_data0001_%05i%s" % (w, u))

+Making Timeseries Plots
+=======================
+
+I don't think anyone will argue that timeseries data is important.  It is
+possible to create it with yt; however, a few things should be noted.
+
+Python is notorious for leaking memory via circular references -- if you
+have a variable *var1* that references variable *var2*, when one is deleted, is
+the other?  Efforts have been made to identify and remove all leaking
+references, but if references are created in your code that generates the
+timeseries data, you may find that more memory is used than is desired.
+
+The process of generating time series data is fairly simple: you iterate over
+the datasets, and generate a value for each. ::
+
+   >>> max_rho = []
+   >>> max_pos = []
+   >>> times = []
+   >>> for i in range(30):
+   ...     pf = lagos.EnzoStaticOutput("my_output%04i" % (i))
+   ...     v, c = pf.h.find_max("Density")
+   ...     max_rho.append(v)
+   ...     max_pos.append(c)
+   ...     times.append(pf["CosmologyCurrentTime"] * pf["years"])
+   >>> pylab.loglog(times, max_rho)
+   >>> pylab.clf()
+
+You could also imagine doing a time-evolution of an averaged quantity::
+
+   >>> avg_T = []
+   >>> times = []
+   >>> for i in range(30):
+   ...     pf = lagos.EnzoStaticOutput("my_output%04i" % (i))
+   ...     v, c = pf.h.find_max("Density")
+   ...     sp = pf.h.sphere(c, 10.0/pf['kpc'])
+   ...     avg_T.append(sp.quantities["WeightedAverageQuantity"]("Temperature",
+   ...                                                           "CellMassMsun")
+   ...     times.append(pf["CosmologyCurrentTime"] * pf["years"])
+   >>> pylab.loglog(times, avg_T)
+
+At this point, you can also write out the data to a file and plot it in another
+plotting package: ::
+
+   >>> f = open("my_data.dat", "w")
+   >>> for i in range(len(times)):
+   ...     f.write("%0.5e %0.5e\n" % (times[i], avg_T[i]))
+
+More complicated analysis can be done as well; :class:`PlotCollections`
+created, slices made, etc.
+
+The package :mod:`fido` inside of yt is also available, but it is not
+well-documented.  It will store information about outputs, associated with a
+given run, and you can iterate over those.  This is altogether a simpler
+process, but it is not resilient against data movement.

+Derived Quantities
+==================
+
+Associated with a given data object, one can imagine various quantities being
+described.  Several of these are already included in yt, and more can be added.
+To access a derived quantity, the property 'quantities' is available in a given
+data object.  It acts as a dictionary, returning callable functions.::
+
+   >>> L_vec = gal1_region.quantities["AngularMomentumVector"]()
+   >>> com = gal1_region.quantities["CenterOfMass"]()
+   >>> avg_T = gal1_region.quantities["WeightedAverageQuantity"]("Temperature", \

+
+All derived quantities accept the parameter :keyword:`lazy_reader`, which
+tells the function to attempt to operate in a memory-conservative fashion --
+reading and then flushing the data back to disk.  This is not possible for all
+functions, notably the :func:`IsBound` function, which checks for
+gravitationally-bound status.

+We first instantiate a StaticOutput, which is a single disk-written timestep of

 will grab the parameter file that you give it, parse it, set up some handy
 units, and then return control to you.::

+   >>> a = lagos.EnzoStaticOutput("my_data0001.dir/my_data0001")
 
 
 But what good is just a parameter file?  What we really want is to be able to
 manipulate the grids, and all the fields stored in those grids.  Fortunately,
 we can access the hierarchy as either 'hierarchy' or 'h'.
-Let's start out by finding the location of the maximum Density.
+
+The 'h' property will instantiate an :class:`EnzoHierarchy` object, which
+posseses information about the grids in a given output, as well as their
+spatial relationships to each other.  Furthermore, :mod:`yt` will store
+commonly-used and expensive-to-generate data in an HDF5 file associated with
+that object -- things like projections, 3D phase profiles, and so on.
+
+All of the data-handling we want to do will be mediated by the hierarchy file;
+so let's start out by finding the location of the maximum Density.
 Note that here we use an inline-unpacking -- find_max returns two values,
 packed into a tuple, so we manually unpack them right here.::

 The Grids

 The hierarchy object has some interesting methods that let us access the data
 in different ways.  Let's start by looking at the grids.  ::

+What the code just did was access the grid files and then spit back the

+this way, but what about generating new fields from our existing fields?
+Well, that's just as easy!  And yt comes with many derived fields

+If you have the `S2PLOT <http://astronomy.swin.edu.au/s2plot/index.php?title=S2PLOT>`_
+bindings installed, you can visualize three-dimensional profiles with yt.  The
+API is nearly identical to that used to generate the lower-dimensionality
+profiles. ::
+

+   >>> prof.add_fields("CellMassMsun", None)
+
+I've wrapped the bounds into the variable *extrema*, to make it more clear.
+Once you have this profile, you can plot it with S2PLOT by calling initializing
+a 3D plot and calling :func:`run`. ::
+
+   >>> vrc = raven.VolumeRendering3DProfile(k, "CellMassMsun", amax=1.0)
+   >>> vrc.run()
+
+They can be generated anywhere -- and serialized -- so if you want to generate
+them on a remote machine and use a local-machine for display, you only have to
+call :func:`store` and then initialize, instead of the standard
+:class:`BinnedProfile3D`, :class:`StoredBinnedProfile3D`.  ::
+
+   >>> prof.store_profile('MyProfile')
+   >>> new_prof = lagos.StoredBinnedProfile3D(a, 'MyProfile')
+
+The retrieved profile is static, and new data cannot be added.  However, it
+becomes useful in the likely circumstance that your data is stored on a machine
+on which is inconvenient to do OpenGL-based data exploration.

+<p>The following recipe opens the parameter file, creates a ‘collection’ of plots,
+adds a few slices, and then saves it at a fixed width.</p>

+<p>I don’t think anyone will argue that timeseries data is important.  It is
+possible to create it with yt; however, a few things should be noted.</p>
+<p>Python is notorious for leaking memory via circular references – if you
+have a variable <em>var1</em> that references variable <em>var2</em>, when one is deleted, is
+the other?  Efforts have been made to identify and remove all leaking
+references, but if references are created in your code that generates the
+timeseries data, you may find that more memory is used than is desired.</p>
+<p>The process of generating time series data is fairly simple: you iterate over
+the datasets, and generate a value for each.</p>

+</pre></div>
+<p>More complicated analysis can be done as well; <tt class="xref docutils literal"><span class="pre">PlotCollections</span></tt>
+created, slices made, etc.</p>
+<p>The package <tt class="xref docutils literal"><span class="pre">fido</span></tt> inside of yt is also available, but it is not
+well-documented.  It will store information about outputs, associated with a
+given run, and you can iterate over those.  This is altogether a simpler
+process, but it is not resilient against data movement.</p>

+we can access the hierarchy as either ‘hierarchy’ or ‘h’.</p>
+<p>The ‘h’ property will instantiate an <tt class="xref docutils literal"><span class="pre">EnzoHierarchy</span></tt> object, which

+Extracting Data
+===============
+
+Oftentimes you will want to export data from yt to plot in another plotting
+package, or to compare against another set of data elsewhere.  (Although, note
+should be made that ever effort has been made to make yt into a
+publication-quality plotter.)
+
+Data objects all have the :meth:`write_out` method, which accepts a field
+list and a filename.  This will dump to text.
+
+However, if you have `PyTables <http://www.pytables.org/>`_ installed, you can
+also export things in a different way: ::
+
+   >>> cube = pf.h.smoothed_covering_grid(3, left_edge=[0.0,0.0,0.0],
+   ...                                       right_edge=[1.0,1.0,1.0],
+   ...                                       dims=[512,512,512],
+   ...                                       fields=["Density"])
+   >>> f = tables.openFile("my_cube.h5","w")
+   >>> f.createArray("/","my_cube_density", cube["Density"])
+   >>> f.close()
+
+This will generate an HDF5 file with the "Density" array from our smoothed cube
+at the root node, and called "my_cube_density".  With PyTables you can nest
+these, set attributes, and access the data through any application that can
+read HDF5.

+Making Simple Plots
+===================
+
+Single Width Plots
+------------------
+
+Making plots can be considered one of the simplest things to do in yt, and at
+its most primitive you can simply declare which plots to make.
+
+The following recipe opens the parameter file, creates a 'collection' of plots,
+adds a few slices, and then saves it at a fixed width.
+
+.. code-block:: python
+
+   pf = lagos.EnzoStaticOutput("my_data/my_data0001")
+   pc = raven.PlotCollection(pf)
+   pc.add_slice("Density",0)
+   pc.add_slice("Density",1)
+   pc.add_slice("Density",2)
+   pc.set_width(100.0,'kpc')
+   pc.save("my_data0001_100kpc")
+
+Multiple Fields Single Width
+----------------------------
+
+The 'save' command encodes the name of the field into the filename.  It is more
+efficient to 'switch' a field than to add a new slice with a different field.
+
+.. code-block:: python
+
+   fields = ["Density", "Temperature", "x-velocity"]
+   pf = lagos.EnzoStaticOutput("my_data/my_data0001")
+   pc = raven.PlotCollection(pf)
+   pc.add_slice(fields[0],0)
+   pc.add_slice(fields[0],1)
+   pc.add_slice(fields[0],2)
+   pc.set_width(100.0,'kpc')
+   for field in fields:
+       pc.switch_field(field)
+       pc.save("my_data0001_100kpc")
+
+Single Field Multiple Widths
+----------------------------
+
+We can zoom in on our slice very easily, and we can define it to do that and
+vary units, too, thus ensuring we have a consistent set of plots.
+
+.. note::
+   We do some fancy footwork here with the creation of *my_pairs* but it is an
+   idiom that can be applied elsewhere.
+
+.. code-block:: python
+
+   widths = [1000.0, 100.0, 10.0, 1.0]
+   units = ['mpc','kpc','pc','au']
+   my_pairs = [ (w,u) for u in units for w in widths ]
+
+   pf = lagos.EnzoStaticOutput("my_data/my_data0001")
+   pc = raven.PlotCollection(pf)
+   pc.add_slice("Density",0)
+   pc.add_slice("Density",1)
+   pc.add_slice("Density",2)
+   for w, u in my_pairs:
+        pc.set_width(w,u)
+        pc.save("my_data0001_%05i%s" % (w, u))
+
+Multiple Fields Multiple Widths
+-------------------------------
+
+Because of the way the slices are created and the fields handled, we set our
+outer loop to be over the field and the inner loop to be over the widths.
+
+.. code-block:: python
+
+   fields = ["Density", "Temperature", "x-velocity"]
+   widths = [1000.0, 100.0, 10.0, 1.0]
+   units = ['mpc','kpc','pc','au']
+   my_pairs = [ (w,u) for u in units for w in widths ]
+
+   pf = lagos.EnzoStaticOutput("my_data/my_data0001")
+   pc = raven.PlotCollection(pf)
+   pc.add_slice(fields[0],0)
+   pc.add_slice(fields[0],1)
+   pc.add_slice(fields[0],2)
+   for field in fields:
+       pc.switch_field(field)
+       for w, u in my_pairs:
+            pc.set_width(w,u)
+            pc.save("my_data0001_%05i%s" % (w, u))

+Making Timeseries Plots
+=======================
+
+I don't think anyone will argue that timeseries data is important.  It is
+possible to create it with yt; however, a few things should be noted.
+
+Python is notorious for leaking memory via circular references -- if you
+have a variable *var1* that references variable *var2*, when one is deleted, is
+the other?  Efforts have been made to identify and remove all leaking
+references, but if references are created in your code that generates the
+timeseries data, you may find that more memory is used than is desired.
+
+The process of generating time series data is fairly simple: you iterate over
+the datasets, and generate a value for each. ::
+
+   >>> max_rho = []
+   >>> max_pos = []
+   >>> times = []
+   >>> for i in range(30):
+   ...     pf = lagos.EnzoStaticOutput("my_output%04i" % (i))
+   ...     v, c = pf.h.find_max("Density")
+   ...     max_rho.append(v)
+   ...     max_pos.append(c)
+   ...     times.append(pf["CosmologyCurrentTime"] * pf["years"])
+   >>> pylab.loglog(times, max_rho)
+   >>> pylab.clf()
+
+You could also imagine doing a time-evolution of an averaged quantity::
+
+   >>> avg_T = []
+   >>> times = []
+   >>> for i in range(30):
+   ...     pf = lagos.EnzoStaticOutput("my_output%04i" % (i))
+   ...     v, c = pf.h.find_max("Density")
+   ...     sp = pf.h.sphere(c, 10.0/pf['kpc'])
+   ...     avg_T.append(sp.quantities["WeightedAverageQuantity"]("Temperature",
+   ...                                                           "CellMassMsun")
+   ...     times.append(pf["CosmologyCurrentTime"] * pf["years"])
+   >>> pylab.loglog(times, avg_T)
+
+At this point, you can also write out the data to a file and plot it in another
+plotting package: ::
+
+   >>> f = open("my_data.dat", "w")
+   >>> for i in range(len(times)):
+   ...     f.write("%0.5e %0.5e\n" % (times[i], avg_T[i]))
+
+More complicated analysis can be done as well; :class:`PlotCollections`
+created, slices made, etc.
+
+The package :mod:`fido` inside of yt is also available, but it is not
+well-documented.  It will store information about outputs, associated with a
+given run, and you can iterate over those.  This is altogether a simpler
+process, but it is not resilient against data movement.

+Derived Quantities
+==================
+
+Associated with a given data object, one can imagine various quantities being
+described.  Several of these are already included in yt, and more can be added.
+To access a derived quantity, the property 'quantities' is available in a given
+data object.  It acts as a dictionary, returning callable functions.::
+
+   >>> L_vec = gal1_region.quantities["AngularMomentumVector"]()
+   >>> com = gal1_region.quantities["CenterOfMass"]()
+   >>> avg_T = gal1_region.quantities["WeightedAverageQuantity"]("Temperature", \

+
+All derived quantities accept the parameter :keyword:`lazy_reader`, which
+tells the function to attempt to operate in a memory-conservative fashion --
+reading and then flushing the data back to disk.  This is not possible for all
+functions, notably the :func:`IsBound` function, which checks for
+gravitationally-bound status.

+
+The retrieved profile is static, and new data cannot be added.  However, it
+becomes useful in the likely circumstance that your data is stored on a machine
+on which is inconvenient to do OpenGL-based data exploration.
