The interactive js plot_state visualizations had an additional method 'hinton' for drawing a hinton diagram of the quantum state. However this method was missing from the non-js plot_state function. This commit adds the missing method. THe hinton diagram implementation here is based on the example from the matplotlib documentation, which can be found here: https://matplotlib.org/gallery/specialty_plots/hinton_demo.html

can you post a version of the figure |
|
@jaygambetta this is what it does now:
Basically just a 2d version of the cities plot:
I still need to look into adding the x and y ticks and labels. Personally I don't find this super useful, especially compared to the 3d bar plot, but I only pushed the PR because the iplot_state function (for the js version) supports this method and it was missing from the local version. (as part of #1229 ) |
|
great. I agree and it looks good but i will not use it. |
|
You need a colorbar as well to make it useful: http://qutip.org/docs/latest/images/visualization-rho-ss.png |
|
@nonhermitian oh, actually this implementation doesn't do color shading. It's binary colors, black (negative) or white (positive) and only the size is adjusted for the value. I didn't check qutip and just referred to the matplotlib docs which did it that way. |
|
yeah there is no color bar its the size of the square |
|
Ok, now with tick marks and labels the same script generates:
|
|
does it have to be one above the other. Can they go next to each other |
|
@jaygambetta sure, I'll put them side by side. I just did top to bottom because I copied the subplot setup from the 3d bar graph function. |
|
|
|
Great. I think we should change the city as well to be side by side |
|
also I think we should change the order of the city labels to match this |
|
@jaygambetta sure, can you open an issue for the improvements to the city plots (just so I don't forget about it) |
