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

[sixwwwwww]

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

Fantastic thankyou so much :) So much clearer now. Thanks again

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
