valipetricele Posted October 25, 2007 Report Share Posted October 25, 2007 Hello, I am using Labview 6.1 and I need to make an XYGraph draw and redraw itself faster. At the moment the graph draws itself as if it would show me every line, instead of making a quick refresh( instant refresh). Please help me. Thank you Quote Link to comment

Thank you As far as I can remember (that means not very far in fact) LabVIEW has never been really fast to draw graph, so you'd better limitate the amount of data to plot. A usual way to do that is to get the plot area size in pixel and not to plot more than 5 point (data) per pixel. To decimate your data I suggest taking min and max of a substract of your array. Hope this makes sense in your application, happy wiring. Quote Link to comment

If you're writing a lot of data often to the graph, you can "defer panel updates" <- do a help search for that. Quote Link to comment
