Charting enhancements

This week's version of Pyrrho 4.8 has modified slightly the output flags that can be added to tables and columns for automatic charting. Table metadata can include Pie, Line, Points, Histogram. Column metadata can include X, Y and Caption. Legend can be usefully added to Pie and Histogram: if legend is not specified Pyrrho writes the captions directly into the chart. The colours are selected automatically. An example is shown here.
In this example the values in the table are added explicitly: in a real application this would be a presentation database and the table would be filled by some business analytics process. Feedback is always welcome on features of this sort.
