I apologize in advance if this has been answered somewhere else before, but I have been unable to find an answer on my own. I am having trouble using the printer object to print chart components. I worked up a simple line chart demo based off the showcase code, and added a CommandButton and printer behavior to print the LineChart component. However, the print out only contains the legend and value ticks along the chart axes. None of the actual data series lines, points, nor the grid backing of the chart show up in the printout.
Is this a known bug, or am I just missing something? If it is a known bug, will it be fixed? Is there a work around for printing chart data?
Thank you, and my code follows:
