Plotting Only the Data Points

To plot a marker at each data point without connecting the markers with lines, use a specification that does not contain a line style. For example, given two vectors,

• x = 0:pi/15:4*pi;
  y = exp(2*cos(x));
  

calling plot with only a color and marker specifier

• plot(x,y,'r+') 
  

plots a red plus sign at each data point.

See LineSpec for a list of available line styles, markers, and colors.
