Regarding ODF import and Export support for HistogramChart

[Regina Henschel]

Hi Devansh,

I have looked at patch set 13 of 
https://gerrit.libreoffice.org/c/core/+/177364

The file libreoffice-schema.rng has errors. I have already commented on 
Gerrit about the doubled attribute frequency-type. For to explain the 
other errors, I need an example of the intended markup, best using 
frequency-type 2. Please write it here to the list. Please start with 
the element <chart:series>. You can assume fictive data with label 
"Results" in cell A1 and values in A2:A101.

Kind regards,
Regina
