[Gnuplot-info] javascript for canvas

[aaron b. <bri...@gm...>]

hi all,
i was shocked to see that noone has been discussing the amazing new
canvas terminal on the mailing list this month! let's start.

i have a web page which displays the canvas plot and mousing panel
correctly, having loaded the several JS and CSS files which are
provided with gnuplot 4.4.0. the JS executes without errors;
mouse_update() and getMouseCoordsWithinTarget() run, but there are no
updates to the panel, clicking on the buttons similarly does nothing,
and there are no labels drawn on the graph when i click it like the
demo. the only value i've seen panel show for X and Y both is
3.258e+8. well, OK.

what i really want is to make datapoints in the picture clickable.
should i be modifying the emitted HTML to add my own mouseover and
click events to the canvas element? has anyone successfully adapted
the provided JS to do something similar?

cheers,
aaron.
