Plotly not displaying panel menu


#1

Using Grafana v5.4.2 on Raspbian Stretch, tried to install the Plotly plugin;
$sudo grafana-cli plugins install natel-plotly-panel
all appeared to install OK, and I got v0.0.5, so restarted Grafana.

Opened Plotly into a dashboard, and found that I just get an empty panel, with no menu at the top. This meant that I am unable to edit the panel to add the Metrics, etc.
I could only remove the panel by rolling back my dashboard to the previous version.

I notice in the documentation, it talks about ‘Building & Compiling’ plotly. Having installed it as above, is it necessary to also compile??
