Addaxis (multiple y axis on left side)

I want to create a plot with multiple y axis on left side and only one y axis on right side. The data is attached.

I want a plot between x versus y and x versus z in left side and y versus z on right side of y axis.

Hi Kashif,

You can go through following utilities in matlab to achieve this -

- yyaxis to create chart with two y-axes - yyaxis

- subplot to create axes in tiled positions - subplot

After going through this I would suggest you to try it out first .

In case of any difficulties, you can refer to this code -

% Read data from the Excel file
filename = 'Data.xlsx';
data = xlsread(filename);

% Extract the columns from the data
x = data(:, 1);
y = data(:, 2);
z = data(:, 3);

% Create the plot with multiple y-axes
fig = figure;
ax1 = subplot(1, 2, 1); % Left subplot for x versus y and x versus z
yyaxis(ax1, 'left');
plot(x, y, 'b', 'LineWidth', 1.5);
hold on;
plot(x, z, 'r', 'LineWidth', 1.5);
ylabel(ax1, 'y and z');
xlabel(ax1, 'x');

ax2 = subplot(1, 2, 2); % Right subplot for y versus z
plot(y, z, 'g', 'LineWidth', 1.5);
ylabel(ax2, 'z');
xlabel(ax2, 'y');

grid on;

% Adjust the positions of the subplots
ax1.Position = [0.1, 0.15, 0.35, 0.7];
ax2.Position = [0.55, 0.15, 0.35, 0.7];

Result -
