Hi,
I can't seem to implement the very excellent thumbnail and area zooms as demonstrated here:
bioinformatics.cancerresearchuk.org/~kelly02/js/RGraph/docs/zoom.html
As far as I can make out they are no longer in the package.
Is there an add on or something I can grab to get them working? They are just what I am looking for!

Hi,

That's quite an old version of RGraph - the thumbnail and area zoom have been removed and there's just the full canvas zoom now.

The area zoom (RGraph.ZoomArea) is the first function in RGraph.common.zoom.js.

I was able to enable the feature on a scatter plot by setting zoom.mode to 'area' and calling RGraph.ZoomArea(myrgraphobject).

I can understand why you wouldn't want to support the feature - probably lots of conflicts with other click events - but full canvas zoom doesn't always work well for pop-up windows with charts in them, especially since it does not seem possible to zoom in on a particular part of the plot.
