_set_format() error when using datacursor() #91

Closed epeters13 closed 4 years ago

epeters13 commented 5 years ago

I get the following error when following the basic example:

`In [1]: plot(arange(10))
Out[1]: [<matplotlib.lines.Line2D at 0x7f56570df278>]

In [2]: import mpldatacursor

In [3]: mpldatacursor.datacursor()

Looks like there were some recent changes in the latest version of maplotlib. I'll have a fix for this shortly. Thanks for the report!

Was there a fix for that? I am still facing this issue...

My apologies for the delay -- Life and work have been rather hectic and I abandoned my side projects for awhile.

This is fixed in https://github.com/joferkington/mpldatacursor/commit/617a25bd664e83968dc11eaed103fe2558864de5 Updating from master will fix the issue right now, but I'll have a new release out shortly, and then the usual pip install/etc will work as well.
