Plot 3 variables on 2D plot

I have three variables that are stored like this:

The growth in rated power when adding EVs for the combination of 1,2,3...36 households

AAG: 36x1 cell that contains 36 1x1000 cells, every of these cells contains 1x1000 double

(This variable I want on the yaxis)

The number of households that are combined: 1-36

(This I want on the x-axis)

How many inhabitants in total the combination has

AAI: 36x1 cell containing 36 1x1000 double

(This I want represented as a color scale)

Hi Joel,

The “scatter” function in MATLAB has a functionality by which you can pass a third parameter along with the x-axis and y-axis variables. This third parameter is mapped to a colour scale and the plotted x-axis and y-axis values are coloured accordingly.

This example on the documentation page of “scatter” shows the same functionality - https://in.mathworks.com/help/matlab/ref/scatter.html#:~:text=Create%20a%20scatter%20plot%20and%20vary%20the%20circle%20color.

In your use-case, you need to set the following variables like so:

“x”: The number of households that are combined.

“y”: “AAG”

“c”: “AAI”

You can then use the “colorbar” command to display the colour scale graph on your plot - https://www.mathworks.com/help/matlab/ref/colorbar.html.
