2D contour plot for 3 known variables
显示 更早的评论
I currently have 4 datasets with 3 variables
SPD = [37.3;37.1;4.9;165]
K = [810;2250;1311;8000]
Level = [4;4;5;1]
I want to plot SPD and K and have a contour of Level, I will obviously have more data points eventually . Level is strictly from 1-5 so I'd ideally like a noticeable change in colour between each value.
Is this possible at all?

SPD = [37.3;37.1;4.9;165] ;
K = [810;2250;1311;8000] ;
Level = [4;4;5;1] ;
[X,Y] = meshgrid(SPD,K) ;
val = repmat(Level,1,size(X,1)) ;
contour(X,Y,val)

This seems to only give me a contour of lines. The axes are what I am after but I was hoping for a 'fluid' contour around the points (SPD,K)

Show us any pictorial example..

This is similar to what I am after where the shades from green through to pink would represent level 1 - 5

Ohh..for this you need to have x, y and level data......do you have it?
