Re: Multiple canvas plots share same state variable?

Show all headers | View raw

Dou you mean to store the state of the "gnuplot" variable on each mouseleave event and write it back each time the mouse enters? I am not sure if this would solve the problem since the canvas also can get redrawn without the mouse entering.

The sourceforge example shows one canvas only. I meant to provide a finite number of canvas with arbitrary plots. The final number of canvases is not known.

Your solution sounds like a workaround to me. I am voting for a complete isolation of the canvas state.
In my opinion gnuplot should generate javascript with static variables using the  plot names:

var gnuplot_plot1 = { }
if (gnuplot_plot1.zoomed) {
....
}

Thus each canvas will get its own three javascript files.
