My requirements were quite bespoke so I spent some time exploring the best charting APIs to integrate into my development. I shouldn't have bothered! I did not think I would find something flexible enough for my needs on the JED but Plotalot is just awesome!
I messaged the developer who responded quickly and was very helpful. I've looked though the code and it is well very well written. Don't waste any more time, try it now and you'll see how great it is!!!
This is a very useful tool for sorting that boring but vital job of link checking. A big thankyou for such an excellent product.
