Looks good to me.

Generally, it would be good to understand what originally caused the warnings, though.

Maybe someone with a better knowledge of numpy and matplotlib should have a look at this and make sure we're not missing a better way to implement the parts that raised the warnings?

Looks good to me, aside from the redundancy.

Generally, it would be good to understand what originally caused the warnings, though.

I think the warning message is raised by the sns.heatmap() function from the seaborn library. It indicates that when it attempts to set identical low and high values for the x-axis (xlims) or y-axis (ylims) limits, it can result in a singular transformation. This is why seaborn automatically expands the limits to avoid this issue.

Marsmaennchen221 · 2023-07-06T21:28:01Z

As far as I understand the warning in Table.plot_correlation_heatmap is only raised if you use an empty table. Maybe it would be better to catch the warning only if the user tries to use this function on an empty table and raise a new warning that informs the user that a correlation heatmap on an empty table will show nothing.
