So here is the one I did using the Construct URL column…
Started off with a URL that looked like:
https://quickchart.io/chart?bkg=white&c={.........}
There are two query parameters in that URL:
bkg=white
c={ JSON structure }
So I took the whole JSON structure, and put that in a template column:
Then defined the Construct URL column as follows:
The first query parameter was simple, so I “hard-coded” that, and the second query parameter came from the template column.
And that’s it
Resultant chart isn’t particularly impressive…
But it’s what the customer wanted
