Hi,
I am using a scatter3 to plot easting, northing and elevation data from a text file loaded in as a table. I have 1,520,371 points but only wish to plot every 10th point. Is there a function that will allow me to do this? Thanks in advance!

If I understand correctly what you want to do, this should work:
x = rand(1520371,1); % Create Data
y = rand(1520371,1); % Create Data
z = rand(1520371,1); % Create Data
T = table(x, y, z); % Create Table
plot3(T{1:10:end,1}, T{1:10:end,2}, T{1:10:end,3})
grid on
The approach will be the same even if the vector sizes are incorrect here.
