Hello,
I understand that you are trying to plot the output on y axis and give the second input as levels in a contour plot.
The contour plot function plots a contour plot of the given data. The variables that are plotted on each axis are only determined by the order in which the variables are passed into the contour function call. There is no differentiation of input and output variable. It can be done like the code below.
If X and Y are the input variables and Z is the output variable. Then the normal contour plot is as follows:
[X,Y,Z] = peaks;%random data
contour(X,Y,Z,20)
To get Z on Y axis just rearrange the variables in function call as follows:
contour(X,Z,Y,20)
The “levels” and other properties of the contour plot can be adjusted to get required levels in the contour plot.
You can refer to the below documentation to learn more about contour plot:
