I think you can use np.any?

PR Summary
Issue #15923
Axes.pie accepts negative values which outputs the wrong pie chart. This issue is caused by not checking the positive and negative of all input wedge sizes of "x" in Axes.pie.
Now it will raise a ValueError, which indicates wedge sizes should be non-negative when feeding negative values into Axes.pie. It is done by adding an if condition right before calculating the portion of all sizes in the "x" `array.
