Incorrect number of input arguments

I wrote the following code, and I got a message error regarding the input arguments:

lgd_1 = legend(app.UIAxes,'dTdhw(°C)','VDHW(L/min)','SP_VDHW(L/min)','Location','northoutside','Interpreter','none','Orientation','horizontal');
title(app.UIAxes,lgd_1,'string(app.Appliance_Model_1) + " Buit by: " + string(app.Appliance_Manufacturer_1), "Test info: " + string(app.Test_info_1)','Interpreter','none')

I got the following error message and I don't know why?!

It doesn't make sense to pass your legend to the title() function. You can remove it:

lgd_1 = legend(app.UIAxes,'dTdhw(°C)','VDHW(L/min)','SP_VDHW(L/min)','Location','northoutside','Interpreter','none','Orientation','horizontal');
title(app.UIAxes,'string(app.Appliance_Model_1) + " Buit by: " + string(app.Appliance_Manufacturer_1), "Test info: " + string(app.Test_info_1)','Interpreter','none')

The problem is that I get the title under the legend, which I don't want to have it.

How about this?

lgd_1 = legend(app.UIAxes,'dTdhw(°C)','VDHW(L/min)','SP_VDHW(L/min)','Location','northoutside','Interpreter','none','Orientation','horizontal');
title(lgd_1,'string(app.Appliance_Model_1) + " Buit by: " + string(app.Appliance_Manufacturer_1), "Test info: " + string(app.Test_info_1)','Interpreter','none')

The following code worked

lgd_1 = legend(app.UIAxes,'dTdhw(°C)','VDHW(L/min)','SP_VDHW(L/min)','Location','northoutside','Interpreter','none','Orientation','horizontal');
title(lgd_1,[string(app.Appliance_Model_1) + " Buit by: " + string(app.Appliance_Manufacturer_1), "Test info: " + string(app.Test_info_1)],'Interpreter','none')

Thanks ;)

Great!

Might need to see more code, or simplify your example down to one that does not depend on "app".

Initial guess is that the title function can only accept an axis object or legend object as the first argument, so you cannot pass both of them as the first two arguments. Since you passed axes to legend in the first line, trying to use legend again may be unnecessary, as the legend would have been put in your axis object already.
