how to deal with point data?

[codeadair]

Hello,everybody! Very happy you could read my Question.Thank you very much if you could give some suggestion. Connectting mass points one by one forms an undee chart. I want to redraw the undee chart next time. Must i stroe these point data to database? If i do so,i should read out these mass data from database when i want to redraw the undee chart. I do think it is an assheaded idea. ICQ:258-235-734 MSN:msnadair@hotmail.com

I have no idea what you're using to draw this chart, but yes, if you want the chart redrawn, you have to have the data available somewhere, whether it is stored in the control that's doing the rendering, or in a database that the control knows how to get to. But this depends entirely on the requirements of the control. Dave Kreskowiak Microsoft MVP - Visual Basic

What type data? X-Y plot type A time series in real-time (like stock quote) Sampling data on a 2D domain regular or irregular (like elevation on the earth) Best, Jun
