Hello everyone,

I am trying to plot two different plots in a single plot with two different Y- axis but on same same X axis. Is there any way to plot. I am attaching the data and an image of what i required. The data for the second plot is in plot2 excel file. Please kindly help me.

My code:

Z = readtable('Atq100_2.xlsx') ;

Y = readtable('plot2.xlsx') ;

data = table2array(Z) ;

N = size(data,2);

Nsp = N/2;

ttlc = {'x=10mm', 'x=250mm', 'x=500mm', 'x=1000mm', 'x=1500mm'};

xofst = [10 250 500 1000 1500];

figure

ylim([-1 1]*250)

xlim([0 1750])

hold on

for k = 1:Nsp

col = [2 1]+2*(k-1);

famp = 5; % Amplification Factor

datacol1 = data(:,col(1))*famp+xofst(k);

hp(k) = plot(datacol1, data(:,col(2)), 'LineWidth',2);

% plot(data(:,col(1))+xofst(k), data(:,col(2)), 'LineWidth',2)

% minx = min(data(:,col(1))+xofst(k));

% maxx = max(data(:,col(1))+xofst(k));

minx(k) = min(datacol1);

maxx(k) = max(datacol1);

plot([1;1]*[minx(k) maxx(k)], ([1;1]*ylim).', ':k', 'LineWidth',1) % Plot Vertical 'scale' Lines

% plot([1;1]*[minx], ([1;1]*ylim).', ':k', 'LineWidth',1) % Plot Vertical 'scale' Lines

plot([minx(1) maxx(1)]-minx(1)+minx(k), [0 0], '-k', 'LineWidth',1) % Plot Horizontal 'zero' Lines

Line_Coordinates = [minx(1) maxx(1)]-minx(1)+minx(k);

LineLength = diff(Line_Coordinates);

end

hold off

hl = legend([hp], ttlc, 'Location','northeastoutside');

Thanks in advance.

Have a look at the documentation and help for yyaxis. There you should find illustrating examples doing what you want. Possibly in combination with subplot or tiledlayout/nexttile to generate multiple axes to plot in.
