Graphing stopped after upgrade from 0.8.6j to 0.8.7e

[sunil]

I updated from 0.8.6j to 0.8.7e.
Upgrade apparently went smoothly.

Now some graphs are not plotting anything but the gprints
showing the current values are working.

For one broken graph, Graph debug output is below.

Attached is an image showing the problem.

Any help greatly appreciated.

Thanks

OK

That graph statement looks fine.
Please see 2nd link of my sig to see, whether data is still collected correctly. Next step is checking the contents of an rrd file itself.
