[matplotlib-devel] Problem with violinplot

[elmar w. <el...@ne...>]

Hi all,

violinplot is crashing with singular matrix data. See example.

Is this behaviour for a singular matrix intended or just a bug?

Cheers
Elmar

y3 = np.ones(N) * 100   # data set causing violinplot problem

plt.violinplot([y1, y2, y3])

plt.boxplot([y1, y2, y3])  # ok
plt.ylim(0,110)
