Plot or mark a single point in App Designer
显示 更早的评论
Hey, i know how to plot lines and functions etc. and am struggling on a real simple step.
I'd like to mark or plot a single point like "y=0 x =100" in a certain color.
It would be even great to write a short Text over or under this point like (X_CP).
Hope someone can solve this Problem.
Have a nice day and best regards,
Ermanno

You have to add a second plot to your figure using hold on, and plot just the single point with your desired color and line style.
Using the x,y coordinates of that point, you can use the text function to add a custom label for that point to your figure.

The same way you plot a line, which you said you knew how to do, but with a single x and single y coordinate. If you need a refresher, check out the documentation for plot.

x = 0:pi/100:2*pi;
y = sin(x);
plot(x,y)
hold on
plot(1.5,0,'rs')
hold off
text(1.5,0.1,"x_CG","Interpreter", "none")
