Scatter plot with colormap and colorbar based on one of the parameters plotted

Hello everyone,

I want to plot three parameters using colored scatter plot where the colormap/colorbar represents the values of one of them. Attached file is the example of the datasets containing data_x, data_y, data_z. My intention is using the data_z as the colormap as well as colorbar of the scatterplot.

Thank you!

Hi,

I understand that you want to plot a colored scatterplot with 'data_z' represented on the color map, and 'data_x' and 'data_y' on the other axes.

Here is the code implementation:

% Load the data from the .mat file
data = load('data_xyz.mat');

% Extract the variables
data_x = data.data_x;
data_y = data.data_y;
data_z = data.data_z;

% Create the scatter plot
figure;
scatter(data_x, data_y, 5, data_z, 'filled'); 
colorbar;
xlabel('Data X');
ylabel('Data Y');
title('Colored Scatter Plot with Z as Colormap');
colormap(jet)%optional

The above figure is the output of the code.

Here is the documentation link for Scatter plot:

Hope this solves!
