Issue Details

I'm writing data to an XY graph on my LabVIEW front panel, and when I run the program for a long time, writing over 10000 points to the XY graph, my code slows down and becomes laggy. How can I fix this issue?

Solution

A workaround for this behavior isĀ setting the plot point style to 0 (Nothing) and the plot interpolation to 2 (Linear Interpolation). This will make the graph have to draw less on the front panel, saving computer resources.
