I'm working on the graph which refreshes everytime the dataset changed. How can I do that? I'm appreciate all of your help. Thanks

how did you do it?

I think everytimes you add new data to dataset it will invoke the chart refresh. My program has a thread which processes incoming data , filters it and feed them to the dataset. You need to turn off the invoke and then turn on for some period if you continuously feed the data too fast though for better performance

i looked for a refreshChart() function or something, but couldn't find one. does it exist?

I mean when you add a new data to dataset. It will automatically invoke redrawing the chart. You don't need to implicitly call function to invoke it unless you turn it off.
