<pre class="k9mail">I'm trying to make 2 scatter plots where the colors of each point <br>corresponds to the value of a 1d array.<br><br>I want to do this so that the colors used in the 2 plots are comparable. <br>That is, in plot 1 a violet dot means the same value as on plot 2.<br><br>I tried the following code. Here values2 is clearly different than values1. <br>But it appears that the plots are colored with the same colors. And the <br>colorbar scales are different. What I want is to have the colorbar scales <br>be the same, and the colors on the plot are different.<br><br>So for example, if point #1 on plot 1 has a value of 0.4, and point #1 on <br>plot 2 has a value of 0.5, the colors used to represent given values on the <br>2 plots are the same. I believe that without colorbar, just using scatter <br>with specific c=value, I do get this result. But adding colorbar I think <br>changes all the colors.<br><br>Any suggestions?<br><br><br>import numpy as np<br>pts = np.random.uniform (0, 1, 100) + 1j*np.random.uniform(0, 1, 100)<br>values1 = np.random.uniform(0, 1, 100)<br>#values2 = np.random.uniform(0.2, 1, 100)<br>values2 = values1 * 0.8 + 0.2<br><br>import matplotlib.pyplot as plt<br>for value in (values1, values2):<br> fig, ax = plt.subplots(subplot_kw={'aspect': 'equal'})<br> cmap=plt.get_cmap('plasma')<br> blah = ax.scatter (pts.real, pts.imag, c=value, s=10)<br> blah.set_array (value)<br> fig.colorbar (blah)<br>plt.show()<hr>Matplotlib-users mailing list<br>Matplotlib-users@python.org<br><a href="https://mail.python.org/mailman/listinfo/matplotlib-users">https://mail.python.org/mailman/listinfo/matplotlib-users</a><br></pre></blockquote></div></body></html>
