Zoom particular part of the chart without enlarging the canvas

Hi,

I'm pretty new to using this RGraph. Been using jqPlot and Flot for some time, but the support seems to be non-existent these days and so I'm looking for a new platform for graphing.

One feature that they have is the ability to zoom like the one here: www.jqplot.com/examples/zooming.php. Basically it allows users to select particular part of the chart they want to zoom in. As I work on large datasets this feature is good to have to analyze irregular data.

Another one is the ability to view which lines to view for multi-lines graph by clicking on the legend. Something like this: www.jqplot.com/examples/kcp_engel.php.

Are there similar built-in features for RGraph? If there aren't, is there a way to implement that for the project I'm working on?

Thanks,
Josh.

Hi,

You could highlight lines using the interactive key:

www.rgraph.net/docs/interactive-keys.html

But the only zoom in RGraph is the full canvas zoom.
