Dear Shivang, Just use the options you have in matplotlib. You can, for example, write help(kwant.plotter.map) you get: Help on function map in module kwant.plotter: map(sys, value, colorbar=True, cmap=None, vmin=None, vmax=None, a=None, method='nearest', oversampling=3, num_lead_cells=0, file=None, show=True, dpi=None, fig_size=None, ax=None, pos_transform=None, background='#e0e0e0') Show interpolated map of a function defined for the sites of a system. Create a pixmap representation of a function of the sites of a system by calling `~kwant.plotter.mask_interpolate` and show this pixmap using matplotlib. Parameters ---------- sys : kwant.system.FiniteSystem or kwant.builder.Builder The system for whose sites `value` is to be plotted. value : function or list Function which takes a site and returns a value if the system is a builder, or a list of function values for each system site of the finalized system. colorbar : bool, optional Whether to show a color bar if numerical data has to be plotted. Defaults to `True`. If `ax` is provided, the colorbar is never plotted. cmap : ``matplotlib`` color map or `None` The color map used for sites and optionally hoppings, if `None`, ``matplotlib`` default is used. vmin : float, optional The lower saturation limit for the colormap; values returned by `value` which are smaller than this will saturate vmax : float, optional The upper saturation limit for the colormap; valued returned by `value` which are larger than this will saturate I hope this helps, Adel On Mon, Nov 19, 2018 at 12:42 PM Shivang Agarwal < shivang.agarwal@iitgn.ac.in> wrote:
Dear All,
I am using the kwant.plot and kwant.wavefunction functions to plot the wavefunction's sqaured amplitude on the system. For my work, I need to compare such plots on two different systems. It is tough to compare the values as the max and min is not defined on the colorbar. For example, if system 1 has a max value of 0.9 it will be shown as yellow. However, if system 2 has a max value of 2.4 it will also be shown as yellow because the max value gets automatically assigned to the top of the colorbar (inferno in this case).
Would it be possible to assign the max of the colorbar to a fixed number, say 5, for all plots. That way the value 5 will be yellow and 2.4 could be orange while 0.9 could be blue - leading to easier comparison between plots of seen side by side.
Any help would be greatly appreciated.
Thanks and best regards, Shivang Agarwal
