How to Colour in Weekends on BIRT Gantt Chart? [message #1638826]

I have a BIRT Gantt chart.
It shows 16 weeks of data. Weeks are delimited by bold vertical lines, days by grey gridlines. I need to colour the background of the weekend cells to make it easier for a user to see if an event crosses a weekend.

There is a forum dedicated to BIRT. I'll move this topic there but in the future you should ask directly on that forum.

Sorry for the delay. Posts with a response sometimes get skipped over, so when Eric moves one and comments in it, it might look like someone responded. What is your BIRT version? I'll try to get an example set up for you.

Attached is a sample that will show one way of doing it in script. The script can probably be cleaned up some. You also might consider setting the scale min and max based on your dataSet values vs just assuming as I did (I noted this in the code comments).

What I did was use afterDataSetFilled to find the min and max of the date series. From there, I extended the range on each side to account for BIRT padding the chart scale by a day on each side. I added a dummy marker range to my chart that I could copy and change the date values of to add to the chart. Finally, I loop through the dates represented in the chart and add a marker range for each weekend using the cloned dummy range. The dummy range is dropped from the chart.

Hope this helps.
