Plotly direct link rendered image

[emanuelepica]

Hi, I've installed plotly on grafana, I've used the grafana docker-compose version for installing grafana (with the plotly plugin) and the grafana image render plugin. It seems that the Direct link rendered image don't work for the plotly panel (render failed). I also tried to install grafana, ploty and grafana render plugin without docker and nothing has changed. I've checked that the image rendering works well on other plugins (like worldmap panel) I already tried to follow the issue #88 and changed the file module.ts in the plugin directory adding the row for the "call renderingCompleted" and then restart the grafana server but also in this way nothing happened (maybe I followed wrong this procedure?). I'm unable to render an image of plotly panels, there is a solution? thank you

@emanuelepica Save panel image works by command:
curl "http://USER:PASS@host:port/render/d-solo/panelid/panelname?orgId=1&from=1588280400000&to=1592341199999&panelId=16&width=1000&height=500&tz=Europe%2FKiev" > d:/test2.png
But it takes 1min 2 seconds to save an image, while saving of regular panel (not Plotly) takes 1-2seconds.
Does anyone know while it takes so long?

Thank you @Alexadra, I will try this solution and let you know if it works and how much time the rendering requires

Hi @Alexadra, unfortunately this solution doesn't work for me...moreover, if it takes more than 1 min I think that we will need to find a better solution to solve this issue. thanks, any other ideas from someone else?

I've tried also the fixed proposed in some other issue (changing the line 520 of module.ts in plotly plugin) but nothing changed.

Do you have any advice?
