Hello,
This makes sense. I will add some static shortcodes in the future. The current ones work with live polling over the JSON API and therefore probably won’t be very SEO friendly, although they do have their uses.
It has already been requested to be able to show the chart while not being logged in. This will be possible in a future release.
I will post here when the static shortcodes are implemented.
I am currently doing the same on the parent plugin.
kind regards
