Hi everyone.

Does anyone knows how to display a single point (x, y), for instance (2.899, -3.677), on a curve plot?

It´s possible to display points on plotting curves using getCursorInf( ) method but I prefer using other approashs.

I would simply do:

figure
plot(curve_x, curve_y, '-b')
hold on
plot(2.899, -3.677, 'r+')
hold off
grid

That would plot the curve with a solid blue line, and the single point with a red plus sign.

It´s work Star Strider.

Thank you very much indeed.
