Control Placement of Markers Along Line
Create a line plot with 1,000 data points, add asterisks markers, and control the marker positions using the MarkerIndices property. Set the property to the indices of the data points where you want to display markers. Display a marker every tenth data point, starting with the first data point.
x = linspace(0,10,1000); y = exp(x/10).*sin(4*x); plot(x,y,'-*','MarkerIndices',1:10:length(y))
