Hi All

I have a listbox from which I choose some signal names and plot them on my UIAXES. now wanted to make a filter button. how could I transfer those signals to the filtering button ?

maybe assuming I have 3 signals already plotted

Please check the attached file. It gives a general idea of how to apply a filter on the current line plotted on a UIAxes. You can modify it according to your requirements.

Your if-statement is returning only one option. Try the following way:

function GraphbButtonPushed(app, event)
            x = str2num(app.Valuesx.Value);
            cla(app.UIAxes);
            hold(app.UIAxes,'on')            
            if (app.Plotb.Value == true)
                if (app.sinBox.Value == 1)
                    plot(x,sin(x),'Parent',app.UIAxes)
                end
                if (app.cosBox.Value == 1)
                    plot(x,cos(x),'Parent',app.UIAxes)
                end
                if (app.tanBox.Value == 1)
                    plot(x,cos(x),'Parent',app.UIAxes)
                end
             end
        end
    end
