Howdy, back again for more torture.
Canvas line graph had the ability to draw out of bounds, via outofbounds property.
Is such a thing available for SVG?
I like to see lines blow out the top boundary with a set MAXY to notify me of wild performance issues.

RGraph isn't that bad, is it?!

It's not a part of the SVG Line chart currently, but I can add it for you for the next version of RGraph.

Howdy Alex,
I should have meant, back to torture you some more.

I'll hang out for the next version.
Appreciated, Anthony.

Don't worry - I haven't forgotten! I'm currently "updating" all of the demo pages and the charts on the website to try and make them appear "more modern". Apparently, according to many places that I've read, RGraph looks "dated".

Apparently, if something doesn't look right out-of-the-box, it must be rubbish!

So I'm tryng to make the charts look more modern. Indeed, if you have a chart that uses the default look, without configuration, the appearance will change if you upgrade to v7.20. Not much though (X and Y axes off, background grid only showing horizontal lines, colors more subdued) and the functionality remains the same.

Hi,

OK I've added the functionality to the SVG Line chart and whilst the next release is probably some time away, you can get the latest code from Github here:

https://raw.githubusercontent.com/heyesr/rgraph/refs/heads/main/libraries/RGraph.svg.line.js

So give it a try, see how it works for you and let me know if you have any issues with it.

Cheers.

Richard
