RGraph is a JavaScript charts library based on
HTML5 SVG and canvas. RGraph is mature (over 17 years
old) and has a wealth of features making it an ideal
choice to use for showing charts on your website.
Version 7.01 (released in October 2025) is the
latest version of RGraph and now includes a new tree
structure object. The accompanying Treemenu object can then turn
the object into a fully dynamic tree menu.
You can read the API documentation for the tree on
the main API documentation page
and see an example of the Treemenu
feature by following this link...
In the April 2025 (v6.21) release a new datagrid object
was added.
This makes it easy to add static or dynamic data
tables to your pages. It can be used whether you use the
canvas or SVG libraries or entirely standalone.
Get the latest version of RGraph (version 7.01, 8th October 2025) from
the download page. You can read the changelog here. There's also older versions available,
minified files and links to cdnjs.com hosted libraries.

Two things:
1. To show a horizontal line across a bar chart to indicate the average percent that is being shown. I used a line chart to show the average but it overflows into the Y-axis labels (see image) and I don't want that.
2. To show some 'floating' text that sits upon the line to indicate the percentage.

I think a better way would be to use the draw event to do the custom drawing - I'm presuming that you don't have any other reason for using the Line chart.
