fast dynamic graphing in VB4

[Scott Mellors]

I am writing a data logging application in vb4. Data is retreived through the serial port using the MSCOMM control and read into the GRID and GRAPH controls

simultaneously. However the GRAPH control (GRAPH32.OCX) cannot redraw its self quick enough as the time interval between each data point can be as fast as 10ms. Does anybody know of a quicker graphing routine which dynamically updated when you supply it with more data points. The graph is only a simple X,Y plot.

Thanks

Hi


I don't know if it will be quick enough, but Felix Haas has written some VB code on this site which may help you out.
