Ask: Sharing the same color-bar between several ternary graphs #72

Closed akinori8888 closed 7 years ago

akinori8888 commented 7 years ago

I want to share color-bar between several ternary graphs which have individual value-range. For example, value-range of graph A is (0, 67), value-range of graph B is (65, 202) I want the color-bar which fits both of graph A and graph B.

Now, I have two color-bars and set of (color and number) does not match between A and B

You can pass in parameters for the color bar limits (vmax and vmin), see here.

If you want one colorbar for all your plots, that's controllable by matplotlib, try this link or search for similar.

I really appreciate your answer, I'll try that.

Additional question, sorry. Is there any function to describe the number in each cell of heatmap like the picture below in python-ternary? default

akinori8888 commented 7 years ago

Sorry for successive questions. I tried following to your answer, but there are three questions. I could set vmin and vmax

  1. How to delete ticks outside the figure, vertical and horizontal ticks of (0,2,4,6,8,10)?

  2. How can I set ticks numbers from (1,2,3,4,5,6,7,8,9,10) to (0.1,0.2,0.3,0.4 ....) ?

  3. How to create subplots and put ternary graph inside the subplots? this is related to the previous question.

There's not a built in function but you could supply the coordinates and use tax.annotate(...) to directly add the text.

  1. How to delete ticks outside the figure, vertical and horizontal ticks of (0,2,4,6,8,10)?

You can turn off matplotlib's axis ticks with

tax.clear_matplotlib_ticks()
  1. How can I set ticks numbers from (1,2,3,4,5,6,7,8,9,10) to (0.1,0.2,0.3,0.4 ....) ?

You can change the scaling or overwrite the tick values directly. See this example.

You can wrap the matplotlib axis for the subplot like so:

 figure, ax = pyplot.subplots()
    tax = ternary.TernaryAxesSubplot(ax=ax)

Or using gridspec:

   from matplotlib import pyplot, gridspec

    pyplot.figure()
    gs = gridspec.GridSpec(2,2)
    ax = pyplot.subplot(gs[0,0])
    figure, tax = ternary.figure(ax=ax)

Thanks for your kind answer, I made it!
