Hello,

We have several tags (with history enabled) that I would like to chart in a Power Chart. My first attempt was to bind the tag to the `pens.[0].display.data` prop. But I can't seem to get anything to display. The settings are: real time, point count=100, recent=1 hour, polling=30s, default aggregation.

Axis config:

The legend does not show, neither does the pen control/selector box.

Am I binding the tag to the wrong property?

Thanks

UPDATE:  
I found that I should probably copy the tag path into the `data.source` property.

Solved as far as I know.
