Unexpected results from litstudy.plot_author_histogram()

[larsgrobe]

Dear all,

I am observing some unexpected behavior in litstudy.plot_author_histogram() in the current master branch. I tried loading bibtex files from Web of Sciences and Scopus, as well as a Scopus csv. In all cases, I get not only a histogram showing the publication counts per author, but I get two histograms (here one blue, one orange), that I can stack. Apparently I have two categories here, but I cannot make sense of this and did not find anything mentioned in the documentation.

Best, Lars.

Thanks for using litstudy and thanks for reporting this issue!

If you do not provide the groups= keywords, then it should only draw a single histogram in one color. Make sure to clear the matplotlib canvas between different calls to plot_... since otherwise the graphs will be drawn onto the same figure.

Do you have an image of the problem and maybe a relevant code snippet?

Thank you - indeed adding a simple plt.clf() after calling plt.savefig() or plt.show() solved this.
