How make a "check box" for select curves to be plotted

[Alan C.]

Hi.

I'm developing a work that consists in plotting multiple curves in one
graph. I wonder if you can create a "check box" (or a toolbar) next to
the graph, to select the curve to be plotted. (excuse me for my
english...)

Thanks.

Yes, you can do this.  Create a DataTable with the full data set, then use the checkboxes to select columns in the DataTable.  Create a DataView based on the DataTable and set the columns selected by the checkboxes, and draw your chart using the DataView instead of the DataTable.  See this as an example:  http://jsfiddle.net/gTxkN/1/

Thanks A Gallant..

But this checkboxes can be implemented in JAVA? because in the example
the checkboxes are in HTML...

I'm not a java developer, so I'm not certain how to code it, but ultimately all your server-side java code has to produce HTML elements for the clients' browsers to interpret.
