How to draw 30000 points in a 2D picture quicklly

[墨轩]

     I have 30000 points,each of which has different color. When drawing,it is desperately time consuming, though I have used the property of delaying updating the front panelmand it is MUCH better than I first complete,but it is not enough and I still can not stand it! 

 Any reply or help will be appreciated! I am waiting for you!

 See the attachment! Thank you!

try the attached.

If you can send all of your 30k points at once, you can do the various operations as 2D arrays instead of using a FOR loop to draw discrete points.

If you need to do chunks of 300 columns at a time, I have ideas of how to do that too.  Let me know.

here's a version that better emulates the original VI operation.

Thank you so much first of all ! Using arrays is really much better than drawing every point,your idea inspires me a lot!  Could you give me your  an E-mail?
