Exception handling with Dataframe of values that occur only once or twice

[romanwolf-git]

Hey, I am trying to plot a Dataframe in which values of the scale occur only once or twice. This always seems to run into a "ValueError: attempt to get argmax of an empty sequence". I can solve this issue by setting xtick_interval = 1. But still I don't understand the error, which would help in order to handle this error, since I am plotting more than 50 plots.

This is my DataFrame

Pkw	Fahrrad	ÖPNV	zu Fuß
NaN	NaN	NaN	NaN
NaN	NaN	NaN	NaN
NaN	NaN	NaN	NaN
NaN	NaN	NaN	NaN
NaN	NaN	NaN	NaN
NaN	NaN	NaN	NaN

If you could suggest any kind of help or a better explanantion, I would be very thankful!

By the way, this is how a Plot looks finally. Somehow the legend is shifted into the plotting canvas. If someone has a solution for that as well?!

This line in plot_likert.py (in def plot_counts) should keep it out of the plot: # Control legend plt.legend(bbox_to_anchor=(1.05, 1)) It seems like your plot has positive responses on the left and negative on the right. Maybe you need to change the anchor to -1.05? Tschuess, Mike

Hi @hbxbgrw7913, these are both bugs, thanks for reporting them! I've moved them to separate issues — #38 (for the original exception) and #39 (for the legend positioning) — and will follow up there.
