No warning raised when there are more than 255 data series within a chart #399
Excel doesn't recognize charts if they have more than 255 data series. This is documented limit. Excel doesn't allow to create a chart from a data region with 256 or more columns, it prints "The Maximum number of data series per chart is 255" when a user attempt to select such region.
One can easily hit the limit when a chart is created programmatically:
When I try to open
I'm using python 2.7.12 and XlsxWriter 0.9.4.
XlsxWriter should raise a warning or even exception (in the next major version) if Excel hard limits are hit.
