Hello,

I have a question about the trend in the Power Chart because it abnormal behaves on my Perspective Client.

When I have a large range set, the trend throws the error "No Trend Data Source available (Bad)" when I reduce it a little I have a line connecting between two points. When I give a small range the last few hours the graph comes back to display correctly. What is the reason for this?

I would think your database query for the large time frame is timing out. You may need a faster database. There are probably messages in your gateway log corresponding to these attempts.
