I get a figure window popping up when I try to plot two graphs both on same gui window with two y-axes. Can anyone please tell me how can i stop figure window popping up. I am putting complete code below, please have a look. Thankyou for your time in advance.
classdef StaticPad_data < matlab.apps.AppBase

You should plot() first and set labels after that. When an axes does not have "hold on" then plot() will clear the axes, which would remove the labels and titles you just put in.

I tried what you told me but the figure window is still poping up. I want both graphs to be plotted in the gui window. How can I do that?

Hi Milind,
You are getting the second plot in the new figure because yyaxis adds second yaxis to the active axis. I assume a new axis is being created in the above case and hence the new figure. To ensure that the new axes are added to the UIAxes of App Designer, change the call to yyaxis into the below code where app.UIAxes are explicity mentioned for the axes.
elseif app.BothButton.Value
hold(app.UIAxes,'on')
yyaxis(app.UIAxes,'left');
xlabel(app.UIAxes,'Time');
ylabel(app.UIAxes,'Temprature');
plot(app.UIAxes,app.Time,app.Temprature,'o-r');
yyaxis(app.UIAxes,'right');
ylabel(app.UIAxes,'Thrust');
title(app.UIAxes,'Thrust vs Time');
plot(app.UIAxes,app.Time,app.Thrust);
legend(app.UIAxes,'Temprature','Thrust','*-k');
end
