An extaordinarily useful piece of code. Thanks.
I find invaluable....
Being able to write a plain text graph file from another code
Box 'zoom' function
Ability to click on 'Axes' to redisplay
...and it would be really nice if.....
Moving cursor on to series indicated which series it belongs to, and that clicking against a series could clear its tick-box.
We could have 'clear-all' function for series tick-boxes
Clicking on a point delivered its coordinates ('hover' not accurate enough)
We had a togglable option to display co-ords alongside points
The axes co-ordinates could be displayed on all four sides of the display, not just two.
