Centering a background gradient color map for a pd.DataFrame Styler object
Unsure if it is possible to leverage matplotlib’s DivergingNorm for color maps under the framework of pandas Styler objects. As an example: Ideally only negative (positive) values would appear red (green). Answer It doesn’t look like there is an option to pass a custom normalization to background_…

Suppress scientific notation in sklearn.metrics.plot_confusion_matrix
I was trying to plot a confusion matrix nicely, so I followed scikit-learn’s newer version 0.22’s in built plot confusion matrix function. However, one value of my confusion matrix value is 153, but it appears as 1.5e+02 in the confusion matrix plot: Following the scikit-learn’s documentatio…

I have a DataFrame I want to turn into a Radar Chart. The DataFrame looks like this when it’s ran… I repurposed some code I found on another Stack Overflow question pertaining to Pandas and Radar Charts and it works for the most part except I can’t get the values of Col B to align properly w…
How to add color gradients according to y-value to a bar plot?
Suppose I have a vertical bar plot like this: MWE per this suggestion: Is there an easy way to color the bars with a colormap according to the y-values they actually span (suppose my color bar goes from 1-12 where 1 is represented by yellow and 12 is represented by dark-blue)? I have tried to adapt this examp…
