Hi rockstar49,
Here are few assumptions I have made based on the description provided:
- The data contains three values probably as columns in the excel sheet i.e., speed, torque & power.
- And you want to plot power on a X-Y grid where X is speed and Y is torque.
Few steps you can follow to achieve the desired plot are:
- Firstly, read the data from the excel-file using “readtable” function.
- Then, create a 2-D grid of speed & torque using “meshgrid” function of Matlab.
- Finally, you can plot the data using “contourf” function.
Here is a sample Matlab script you can refer to:
data = readtable("Book1.xlsx");
[speed,torque] = meshgrid(data.S,data.T);
contourf(speed,torque,power)
In the above script, "power" is a 9 * 9 matrix which we got by multiplying each element of "speed" with all the elements of "torque".
Please refer the following documentation for further understanding of the functions used:
