Example file from Excel with pie charts, custom labels are set to 8 pt and 20
pt

Attached documents have charts with custom data labels set with text only.
There is custom font size set for the whole data series, which seems to be
imported correctly, but it is not applied in the chart display.


Steps to reproduce:
1.      In Excel create a simple chart and enable data labels
2.      Enter custom data label text on the labels
3.      Select the data series on the chart and set a custom font size on the
Home – Font ribbon for the whole data series
4.      Save the file and open it in Calc

Actual results:
When opened in Calc the font size appears to be about 14 pt size, regardless
the set value. Attached files used 8 pt and 20 pt sizes. The Data Labels ->
Font tab interestingly reflects these values correctly, unlike the chart
rendering.

Expected results:
Font sizes applied for the custom labels of the data series.
