Since we couldn't wait, I have found a workaround. I am posting it here in
case it helps someone when using an unsupported JS function.
In flotr.js I just made a small modification:
---
this.ctx = c.getContext('2d');
this.octx = oc.getContext('2d');
// add these lines:
if (!(this.ctx.scale)) {
this.ctx.scale=function(x,y) {};
this.octx.scale=function(x,y) {};
this.ctx.translate=function(x,y) {};
this.octx.translate=function(x,y) {};
}
// then all is well:
if(!Prototype.Browser.IE){
this.ctx.scale(o.resolution, o.resolution);
this.octx.scale(o.resolution, o.resolution);
}
---
So the trick was to add the missing function through JS if they were not
available.
I am still curious about AJAX and <sleep> though?
Kind regards,
Anze
