# Does my 3D surface plot look ok?

I have a feeling that my graph doesnt look right (not clear and concise enough), but it might well be, just need to settle my mind about it.
I am plotting Wind Chill against Temperature (Celsius) and Windspeed (m/s).
This is my code I have used
%My Matrixes, z2 is the windspeed, z3 is the temperature%
z2 = [0,1.50000000000000,3,4.50000000000000,6,7.50000000000000,9;10.5000000000000,12,13.5000000000000,15,16.5000000000000,18,19.5000000000000;21,22.5000000000000,24,25.5000000000000,27,28.5000000000000,30];
z3 = [-50,-45,-40,-35,-30,-25,-20;-15,-10,-5,0,5,10,15;20,25,30,35,40,45,50];
%my Meshgrid%
[X, Y] = meshgrid (z3, z2);
&Calculations to convert C to F and m/s to mph to fit into my formula%
TEST1TEMP = X * 9/5 + 32;
TEST2SPEED = Y * 2.23693629;
&Wind Chill Formula%
Z = 0.0817.*((3.71.*sqrt(TEST2SPEED))-0.25.*TEST2SPEED+5.81).*(TEST1TEMP-91.4)+91.4;
&My surf code%
surf (X, Y, Z) xlabel ('Temperature (C)') ylabel ('Wind Speed (m/s)') zlabel ('Wind Chill')
This is how my figure looks
I worry it looks a little all over the place, would appreciate guidance on if it looks ok, or if not how to sort it. Thankyou very much Phil

may be you can make it look better like this:
[X, Y] = meshgrid (-50:0.5:50, 0:0.5:30);
TEST1TEMP = X * 9/5 + 32;
TEST2SPEED = Y * 2.23693629;
Z = 0.0817.*((3.71.*sqrt(TEST2SPEED))-0.25.*TEST2SPEED+5.81).*(TEST1TEMP-91.4)+91.4;
surf (X, Y, Z), xlabel ('Temperature (C)'), ylabel ('Wind Speed (m/s)'), zlabel ('Wind Chill'), view([-120 45]), colorbar

You could turn off the 'EdgeColor' (black lines) of the surf by setting it to 'none' or use a mesh() instead of a surface (I typically recommend this for dense data.

Thanks Sean, will try that out when i get a moment
