question on clearing axis (ax.clear())

[montanaviking]

I am noticing the following warning messages when I clear data from a Smith chart plot using ax.clear(). /usr/local/lib/python3.4/dist-packages/smithplot/smithaxes.py:1060: DeprecationWarning: object of type <class 'numpy.float64'> cannot be safely interpreted as an integer. for xs in np.linspace(x0, x1, x_div + 1)[1:]: /usr/local/lib/python3.4/dist-packages/smithplot/smithaxes.py:1064: DeprecationWarning: object of type <class 'numpy.float64'> cannot be safely interpreted as an integer. for ys in np.linspace(y0, y1, y_div + 1)[1:]: #####################################################################################################################

My code follows below and removing the ax.clear() removed the above warning messages. replacing ax.clear() with ax.cla() gave the same results. #############################################################

if I remove the ax.clear() line

Can you provide a more complete test case for your function? Just a bit of sample code that is enough to wrap your function would be enough.

I'm quite confident that I have a fix, but I'd like to produce a test case to verify it before I try to get it pulled back into the project.
