Example charts in the documentation would be useful


Posted by Steve at 01:28 on Wednesday 14th August 2024 [link]
It would be really helpful if how-to documents e.g. https://www.rgraph.net/canvas/howto-line-dual-color.html had an actual example of the graph. Without actually implementing it to try, I can't be 100% certain what a dual line colour graph looks like.

Thanks

I originally had examples on most of the pages on the website but removed them because I couldn't figure out why the site was performing so badly in search.

But I think I might have resolved that (perhaps... we'll have to wait and see!) so I'll start adding the example charts back on the various pages.

In the mean-time - here are some demos that you can find in the download archive...

...that show dual color charts:

demos/line-dual-color-range.html
demos/line-dual-color-scrolling.html
demos/line-dual-color-threshold.html
demos/line-dual-color.html

demos/line-clipping1.html
demos/line-clipping4.html
demos/line-clipping5.html

demos/line-trendline-dual-color.html
demos/scatter-trendline-dual-color-explode.html

This demo on the blog is also (sort of) dual-color:
