Hmm my Grafana5 produces correct images. iam a bit puzzled now

[nbuchwitz]

Even with the load service (or another with more than two rows)? In my environment all graphs with <= 2 rows are fine.

[Mikesch-mp]

Got it. Seem this is a Grafana 5 bug. Only happens if the dashboard has more then on panel in it or is created with version 4. Need more testing before i open a bug report

[Mikesch-mp]

If you readd rows, the graphs look normal again.

Will open bug report at Grafana

I have created a new dashboard from Grafana v5.0.1 and rendered images still are cropped using indirectproxy only, if using proxy same error. It only happen on graph services with more than two rows.

[Mikesch-mp]

I cant reproduce this with grafana 5.1.3 anymore. If someone still have this problem, please open a issue over at Grafana, because this is not a failure of the module.

[nbuchwitz]

@juangranados if the error stil exists check your graph height in the module configuration. In my case this helped to avoid the crop (300px should be fine)

[Mikesch-mp]

@ALL if the legend gets only cropped its not a render problem, then the size is just to small.
