I am not sure if this is a user issue or a development issue. Using version 1.4.2 My code allows the user to hone in on a specific contour range, by changing the minimum and maximum of the contour and the number of levels. I am using colorbar "extend" to prevent any white patches, as the data may have values outside the contour range.
I want the extensions to have tick values but I can't seem to figure out, how to do it? This is my code import numpy as np import matplotlib.pyplot as plt xi = np.array([0., 0.5, 1.0])#xi data yi = np.array([0., 0.5, 1.0])#yi data zi = np.array([[0., 1.0, 2.0],[0., 1.0, 2.0],[-0.1, 1.0, 2.0]])#zi data n=5#number of levels of user specified range umin=0.5#user defined minimum of contour umax=1#user defined maximum of contout u = np.linspace(umin, umax, n)#user specified contour levels cbtics = np.hstack([zi.min(),u,zi.max()])#contour ticks including maximum and minimum of zi plt.contourf(xi, yi, zi, u, cmap=plt.cm.jet,extend='both')#plot contour cbar=plt.colorbar(extendrect='True',extendfrac='auto',spacing='proportional')#plot colorbar print cbar.ax.get_ylim()#show y limits print cbar.ax.get_yticks()#show yticks plt.show() Using the user entered values: ylim are (-0.25, 1.25) but the yticks are: [ 0. 0.2 0.4 0.6 0.8 1. ] range from 0 to 1 I'm guessing that the difference between ylim (-0.25 to 1.25) and yticks (0 to 1) is that I am using extensions, so is there no way to update y ticks to include the extensions so that I can assign labels to the extensions? -- View this message in context: http://matplotlib.1069221.n5.nabble.com/Assign-labels-to-colorbar-extensions-user-or-development-issue-tp44392.html Sent from the matplotlib - users mailing list archive at Nabble.com. ------------------------------------------------------------------------------ Comprehensive Server Monitoring with Site24x7.
