In the TOP N report we are able to View the Barchat at the end of each node. but once we Export to a PDF Bar chart was not showing.please provide solution.
Please try internet explorer and see if the chart will be displayed in the PDF
Maybe because values of "Node Reacheability (avg)" is 0.0% for all the nodes displayed :). Try for a node which has some non-zero value and see if the bar chart is displayed for it,
BTW, this issue is already reported to HP ... refer to : http://support.openview.hp.com/selfsolve/document/KM00659488
