Re: Add data to a GogBarColPlot with stacked columns

[Antonio Álvarez Feijoo <aalvarez igalia com>]

Thanks a lot, I was desperate... :)

Another problem that I still having is that I don't know how to remove the
content of the widget (title, chart, legend, etc) to paint another
different chart inside.

If someone could help me I will be grateful :)
