how to prevent plotting more curve than the axis limit in app uiaxes

app.Curve_sim.XLim=[-(b1+2) 0];

app.Curve_sim.YLim=[0 (a1+2)];

one can find more plots below 0@Y while the YLim is still above 0

Put those data below your limit to NaN.

x=1:50;
y=randi([-5,25],1,50);
threshold = 0;
y(y<threshold)=NaN;         % Set those value below your limit to NaN
plot(x,y);

Thanks very much!

Your answer is available. However, X axis limit is effective, I wonder whether more direct solution can fix this problem.

At other code, the Y limit is also effective. I did not find a difference between this one and the other.

I finally find the Box style was missed Clipping check. Thanks all the same
