How much of Samples can a Vi generates

[bseguin]

The graph takes a while to refresh.

This is why I suggest you to reduce the number of point you display.

Anyway, your eyes cannot see the difference between all of them....

Run with less point and then select your graph and try to move it with the mouse.

every time you do, you force the graph to redraw which takes a considerable amount of the processing power of your 2D video card. depending of your video card, it can take forever.

Hello Sir,

How to Reduce the points...?? but I need 1 minute data

[bseguin]

Keep your data in a variable (shift register, global, getset*functional global*)

Then only display a certain amount of those point, let's say that you cannot display more than 1000 points depending of the resolution of your screen and area of your graph. So parse all your data in a for loop and accumulate in a shift register only enough number of point to represent all your graph. let's say that you show only 1 point on every 1000 points.

That reminds me of the "Displaying Data" section in

Memory Management for Large Data Sets

there's a demo contained in:
