Build 3.0.0.69 of xlsgen includes a fix pack for charts.

It includes the following :

- rendering of charts with missing or inconsistent number of values in series. This is particularly useful when the datasource used for a chart has one or more gaps in it. The rendering does not show fake bars or lines that until this build were created by default to fill the gaps.

- rendering of stock charts : actual rendering of high-low lines and candle sticks.

- line2d with markers : there was a reason why we would not always read correctly the markers in a line2D chart, either from a XLS or from a XLSX file

- chart markers are now exposed in the automatic source code generator


This adds up to quite a bit of improvements on the chart front.
