One more crash on plot with "minvalue must be less than or equal to maxvalue"

[ibobak]

I saw this post https://github.com/davidwhogg/TheThresher/issues/28 but in my case the crash still has place, and it looks like I know under what conditions it happens.

I have almost all shap_values equal to 0 and some of them equal to a negative value: I attached this file here:

shap_summary_test_150000095_gm_test.png.csv.gz

After that this code

fig, ax = plt.subplots(1, 1)
shap.summary_plot(a_shap_values, a_pdf_with_features_only, plot_size=(15, 8), show=False)
ax.set_title(a_title)
plt.tight_layout()
fig.savefig(a_file_to_save)

crashes with

It happened to me as well. But the error went away if I decreased max_displace value.
