If you then execute

[msg,warnID] = lastwarn

then what shows up for warnID ?

[Nitin Phadkule]

>> [msg,warnID] = lastwarn

msg =

'Marker input is ignored.'

warnID =

'MATLAB:graphics:constantline:IgnoredMarker'

Thanks for the reply, i got the reson of error but i want markers to be shown below. Please suggest how to supress warning.

[Walter Roberson]

I do not see any markers. I see line style '--'

[Nitin Phadkule]

ohhh yes it is line style, here is my code. please suggest the solution

This is my related code

            plot(app.UIAxes_2,theta,v1, ...
                theta,v2);
            legend(app.UIAxes_2,{'V','I'},'Location','northeast','AutoUpdate',"off")
            xlim(app.UIAxes_2,"tight");  
            yline(app.UIAxes_2,0, 'k_', 'LineWidth', 2);
           
            xline(app.UIAxes_2,c,'b--', 'LineWidth', 2);
            xline(app.UIAxes_2,90, 'k--', 'LineWidth', 2);

[Walter Roberson]

yline(app.UIAxes_2,0, 'k_', 'LineWidth', 2);

Underscore is a marker style that indicates a horizontal line. You want

yline(app.UIAxes_2,0, 'k-', 'LineWidth', 2);

[Nitin Phadkule]

Thanks after removal of yline warning disappeared.

[Walter Roberson]

Something in your code invokes either xline() or yline(), and specifies a marker in doing so. For example,

xline(4, 'r*')

However, xline() and yline() do not permit markers.
