Hello,

Consider I have a smple line. I want to add arrow (for example 4 arrows to this line) and show it in plot. Is it possible?

plot(x,y)

You may add marker ‘>’ to your plot. The below command plots the line with markers.

plot(x,y,'->')

If you specify only a marker symbol without a line style (as shown below), then plot displays only the markers with no line connecting them

plot(x,y,'>')

You may refer the following documentation to add markers

This does not draw an arrowhead pointing in the direction of the line. It only adds a right-pointing triangle symbol marker at each datapoint.

See my function arrowed_line, which adds arrowheads to the data of the line plot.
