Using XY-Plot to plot Earth longitude and latitude

[minhhoang_65]

Hello everyone, I am new to LabVIEW and I am trying to use XY-Plot to graph Earth longitude and latitude (like the image below):

However, my code did not work well, nothing appeared except the scaling of x and y axis changed. I cannot see any problem here, could someone help me point out what I did wrong? 

Thank you very much!

You did not attach your VI, but just an image of the block diagram…

You use an ExpressVI just to create a plot.

You use matrix functions when they aren't needed.

You do stuff in a loop theat belongs outside the loop.

Example:

And if you don't like loops and the colors blue & pink, here's an alternative 😄

Thank you so much! Got it now!
