问题 I've got too many features in a data frame. I'm trying to plot ONLY the features which are correlated over a certain threshold, let's say over 80%, and show those in a heatmap.

Here is the code that I tried. import seaborn c = newdf.corr() plt.figure(figsize=(10,10)) seaborn.heatmap(c, cmap='RdYlGn_r', mask = (np.abs

问题 I want to use the onclick method to select a range of data on my matplotlib graph. But the thing is, I can't do that more than once and update the plot. I have some ideas to do this, one of them would be to make a list of plots where I jump to new indices after I appended the new picture ... but mostly I would like to be able to store the information from the click ( event.xdata ) two times to color the area under the graph in that section - but for starters it would already be an achievement
