scikit-plot scaling is wrong

Question

I'm trying to plot a confusion matrix in a jupyter notebook and the plot does not display properly.

My code is:

import scikitplot
plt.close()

scikitplot.metrics.plot_confusion_matrix(y_test, y_predicted_test)

and this code produces the plot:

Any suggestions on how to get the plot to display properly will be greatly appreciated.

If you have matplotlib==3.1.1 version installed, just downgrade it. I have encountered the same problem and version == "3.0.3" works fine.

The problem is with the "imshow" function because the same issue araises when plotting heatmap from the seaborn package.
