Hi Kezman,

Judging from the spatial scale of the plots, I think there’s no zoom in here. Since I see there’s a sharp drop in density, my naive guess is either the blob is completely destroyed, or you lose tracking the blob (maybe due to deceleration).

My suggestion is that before tracking an individual blob, just plot the entire domain, then you’ll have a sense of what’s going on, and then you could determine the location of blob and track it easily.

Btw, you could also set origin=‘native’ (as you did previously), which will display the absolute coordinates in the plots and help to clarify the issue.

Let me know if it did not work!

Best wishes,

Hi Suoqing and all,

I tried following the examples for projection generation that are shown in the yt manual but my plots are still not coming out as desired. The first three plots I have plotted are indicated below. Plots for checkpoints 1 and 2 are fine but checkpoint 3 and others that follow are coming out as either extreme zoomed in or distorted. Any ideas how I might correct this?

Thank you,

Kezman

Hi Kezman,

?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: http://yt-project.org/docs/dev/visualizing/plots.html#slice-plots <http://yt-project.org/docs/dev/visualizing/plots.html#slice-plots>

Best wishes,
