plotsparsemarkers

A function that adds only a few markers to lines in an existing plot rather than 1 per x-value.

[h =] plotsparsemarkers(hp, hl, markerStyle[, numberOfMarkers = 6 [,staggered = true]])
The function takes the handle returned from a plot call and adds a few markers along each line rather than the default of one marker per x-value.
The type of marker has to be given for each line you want a marker on.

The legend is also updated assuming that the handle to it is given.

For plots with multiple lines the markers are staggered between the lines so that they wont exactly line up (and possibly cover each other). This feature can be turned off if you want aligned values.

The function returns a handle to the new "lines" to allow further manipulation.

plotsparsemarkersdemo.m is a simple demonstration of the functionality. It should be very easy to get up and running with this.
