All of a sudden the pie charts that use the default "request summary pie chart" portlet on our production environment have started not to show % values around the graph. Tooltip source works fine but % values do not exist.
I see this kind of behavior with bar charts, too. The tags stop appearing for a few days, then they reappear for a while. Tooltip continues to work, same as what you are seeing. Obviously, there is a flaw in the code and it has been this way for a long time. Open a case with HP but it probably will not get very high priority.
Indeed you are right, it is happening in the bar charts as well. As far as I have dug into the depths of PPM, it is not quite possible for me to modify this tag - it is probably related to the rendering method PPM uses to generate the png files created for these portlets. I did open a case, but did not get any response. Hoping to get the tags back with my fingers crossed. :)
When I used kSupport command I recieved this error:
