Mirrored y-data for profile plotting?

Hi again, I am struggeling with the plausibility of my profile plots. While the data seems plausible on the x-axis, the y-axis should be mirrored from my understanding of pedestrian dynamics.. The scenario is still the same as already known.. In the simulation itself, the pedestrian move from the train (y-range 0.0 - 3.0m) through the doors onto the platform (y-range 3.25m - 6.25m) from where they can move to the outside.

The shown image is the inside of the train whereby the highlighted areas are corresponding to the position of the exit doors. Problem is , that the areas with high density should be right before the exit doors (y-value 3.0) and not on the bottom at y=0.

Am I doing something wrong or is there a bug in my files? Uploaded here: https://uni-wuppertal.sciebo.de/s/tdUqwEY3wQFQcGk

Thanks again! David

Sounds likethis

could you try the solution suggested in the link and report back?

see _Plot_profiles.py, line 80-83 and play with it

    im = plt.imshow(density, cmap=cm.jet,
                    interpolation='nearest', origin='lower',
                    vmin=0, vmax=np.amax(density),
                    extent=[geominX, geomaxX, geominY, geomaxY])

David can you post a picture of the geometry?

Of course - here is a snapshot from Smokeview. I will try the tip from Gregor later..

All right, Gregors tip did work, thanks :)

did you use origin='upper'?

Can you post your changes?

supplement: It works with

origin='upper'

Should we close the issue?

Yes, I set origin='upper' in lines 81, 112 and 132 since this problem was generally inside all plots. Now the y-axis is drawn correctly for density, velocity and flow.
