Plot 3 scale graph
显示 更早的评论
Hi I need help with this code.
Weight=(37000:2000:74000);
CG=(16:1:42);
Index=(((Weight/1000)*(CG-25)*0.041935)+50);
I want to do a scattered plot with Weight on the Y axis, Index on the X axis(Bottom) and CG on X axis (Top). Please help.

Hi Anoop, you can do this
Weight=(37000:2000:74000);
CG=(16:1:42);
Index=(((Weight/1000)*(CG-25)*0.041935)+50);
figure
h = scatter3(CG,Index,Weight);
First you will need to make sure your Weight and CG are of the same dimensions. One is 1x19 and the other is 1x27 of which you cannot calculate index from. Once you do that, from there you can look at all the scatter3 plot options to change the graph or you can do this interactively with the figure edit tools.

You need to use meshgrid to get all possible combinations of Weight and CG:
Weight=(37000:2000:74000);
CG=(16:1:42);
[x, y] = meshgrid(Weight, CG);
Index=(((x/1000).*(y-25)*0.041935)+50);
h = scatter3(y(:), Index(:), x(:));

Hi I am trying to get a graph like the image below

I don't know if any graph like that is built in. It looks like you'll have to create something very custom.

I don't really know. Perhaps you can get it by manipulating the camera angle. Or else just create it at a very low level with calls to line().
