Display errors as legend names

Open nnuss opened this issue 9 years ago • 0 comments

@dgryski and I were pondering another problem and mused that it would be possible to return an empty series with the .Name containing the error in EvalExpr(). It's then possible to make an empty graph and show the error text in the legend.

This is targeted to format=png - but is generalizable to other formats.

Should we honor &hideLegend=true ?
