Bug 351580

Description Otavio Pontes 2011-07-08 10:32:24 EDT

Build Identifier: M20110210-1200

When I run a systemtap script using the 'run w/ Graph' option and choose the Line (or Scatter) graph, the graph view is opened and I can see the graph Axis, but the graph content is not displayed.
Using other graphs options (like pie chart) works fine for me.
I'm using systemtap plugin version 0.7.

The log shows the following exception:
