Hi Kezman,<br class="">
<br class="">
?origin? specifies the axis and your plot domain, and what you?re looking for is the ?center? parameter, and provide the coordinates of the blob to the parameter ?center?. You can find some similar SlicePlot examples with a specified plot center here: <a href="http://yt-project.org/docs/dev/visualizing/plots.html#slice-plots" rel="noreferrer" target="_blank" class="">http://yt-project.org/docs/<wbr class="">dev/visualizing/plots.html#<wbr class="">slice-plots</a> <<a href="http://yt-project.org/docs/dev/visualizing/plots.html#slice-plots" rel="noreferrer" target="_blank" class="">http://yt-project.org/docs/<wbr class="">dev/visualizing/plots.html#<wbr class="">slice-plots</a>><br class="">
