The latest version of RGraph - version 6.20 - is now available to download. You can read about the changes for this new version on the changelog page (https://www.rgraph.net/changelog.html).
More changes to the ModalDialog so that the page's scroll-bars are disabled when the dialog is shown. Of course, they're re-enabled when the dialog is hidden. The SVG Bar chart, Horizontal Bar chart and Bipolar chart have had their highlighting updated so that it's no longer drawn above the relevant axis. Also, I've added persistent tooltips that stick around after they're shown.
Or you can download RGraph either from here (GitHub) or from the RGraph websites download page:
