getpts

Select points with mouse

Syntax

• [x,y] = getpts(fig)
  [x,y] = getpts(ax)
  [x,y] = getpts
  

Description

[x,y] = getpts(fig) lets you choose a set of points in the current axes of figure fig using the mouse. Coordinates of the selected points are returned in X and Y.

Use normal button clicks to add points. A shift-, right-, or double-click adds a final point and ends the selection. Pressing Return or Enter ends the selection without adding a final point. Pressing Backspace or Delete removes the previously selected point.

[x,y] = getpts(ax) lets you choose points in the axes specified by the handle ax.

[x,y] = getpts is the same as [x,y] = getpts(gcf).
