Hi Zoran
Have a look at http://www.chestysoft.com/xgraph
This is the simplest chart generator I have found although you will need to load your data into the chart as below (the second parameter being the value)
I have an example form if you would like a copy. I sent it to the publisher, but he has not loaded it to his manual. He only has Delphi and VB examples.
Regards
John
