Great news I've been hard at work on improving this code.
I've made some nice progress to make it all user friendly.
A minimized chart is automatically enlarged when a toImg function is run
First of all the function toImg will run the exp() function and send a
blank data/or its own id.
exp() will determine the element that made the request and expand the image
when minimized
if (obj != document.getElementById('b2')){
document.getElementById('img_div').style.width="400px";
document.getElementById('img_div').style.height=200px";
document.getElementById('b2').innerHTML = 'hide popup';
document.getElementById('b2').oldText = null;
}
else
{
//regular code
}
//The image returned is set width and height (display) it does not clutter
the screen. I found the best way of doing it is to do it when the image has
been successfully created, rather than try and mess around with the image
data being sent out or returned.
You need to
1) give the image an ID.
2) Lookup that ID.
3) Apply the appropriate style height and width to the displayed image.
