Hello Joseph, Thanks a lot for the information. I will try this method and see what I can do with it. Best regards, Shivang Agarwal On Mon 19 Nov, 2018, 7:35 PM Joseph Weston <joseph.weston08@gmail.com wrote:
Hi,
Thank you for the quick response. When I try *kwant.plotter.map(sys, value, vmin=0, vmax=2) *I get the following error:
ValueError: Only 2D systems can be plotted this way.
My system is a 3D system. I would be glad if you could help me out in this regard.
As the error message says, 'kwant.plotter.map' doesn't work for 3D systems. Matplotlib does not have very good support for 3D plots in any case, and it's not clear that there's a general "best way" of plotting a 3D scalar field.
Probably your best bet will be to reduce the dimensionality of what you're trying to plot.
Failing that, you could try using 'kwant.plotter.interpolate_density' (available in the current development version of Kwant and in the soon-to-be-released Kwant 1.4) with the 'ipyvolume' [1] package; something like:
import ipyvolume
...
field, box = kwant.plotter.interpolate_density(syst, some_density)
field = field.squeeze() # ipyvolume requires a rank-3 array
ipyvolume.quickvolshow(field)
Note that the above code is incomplete and untested; it's just to show how you could glue the relevant pieces together.
Happy Kwanting,
Joe
