Please can the auto sizing option be clarified. From GitHub it appears that adding ‘,auto’ onto the height command activates this. The example given uses:
height=200,auto
What is the purpose of the 200 if the chart is being auto sized?
I tried using the option on some charts on my forum. In one case
height=600,auto
was changed to
height=571,auto
In all the other charts I tried it on the original (guessed) height value that I’d used wasn’t changed.

auto is there by default, it means we guess the height and update it.
If we happen to measure wrong you can remove the auto part and just hardcode a more correct height.
