[Gramps-devel] Statistics Chart new features and problems with Gramps CVS HEAD output formats

[Eero T. <eer...@ne...>]

Hi,

I've just added some new features to the StatisticsChart plugin in CVS HEAD:
- Five new statistics chart types:
             - Child counts
            - Marriage places
            - Marriage ages
            - Ages when first child was born
            - Ages when last child was born
  (These use Don's new age calculation function in ReportUtils, thanks!)
- Pie charts with a legend are used instead of Bar charts if the number of
  items in the chart is below a user definable number.  Pie charts and
  legend are produced with Don's new ReportUtils functions. Bar charts are
  still drawn with my own code (I want labels right aligned with bars,
  and needing a legend for a barchart seems kind of redundant)

However, I'm having problems with Gramps output:
* OpenOffice:
  - String widths are calculated incorrectly
    (stable version has same problem with StatisticsChart)
  - Although I select statistics_chart.sxw as the file name, it will
    create/overwrite a file named as statistics_chart.sxx.sxw
* PDF:
  - Doesn't show the legend at all, otherwise looks nicer than OO output
* PS:
  - Shows just the boxes for legend, but doesn't fill them or
    include the text

You can see examples of the problems (and new StatisticsChart features :))

If you have suggestions for better Pie output colors (rgb triplet values), 
please mail me...


Btw. When I select the "Print..." output option for the report,
I get the following traceback:
