You might also be able to plot using a categorical() as the x axis. (It may work fine for you, but its impractical for me.) The following plot is produced by latlim = [39 47]; lonlim = [-81 -70]; figure ('Color','w'); usamap ('New York') shi = shaperead ('usastatehi', 'UseGeoCoords', true,. As I was trying for a linear increasing frquency, it works perfectly for me. You can also move the points and triangles of the mesh around by dragging these vertices to it. scale. Theme Copy x = 0:0.1:pi; y = sin (x); p = plot (x,y,'o-','MarkerIndices',10) You can also specify marker properties, such as the face color and edge color. The question we are working with now is how to figure this out with the data view. Just make sure you understand how it works before implementing! Line 8 does this, creating a variable (itimeArray) the same length as frequency, the 'zeros' function dictates that each value itimeArray will start as a '0'. 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. Matlabs GUI allows you to view this clearly: you can choose any of the faces from the mesh and you can click the triangle mesh to create a mask for the vertices and cells. For example: plot(1,2) returns simply a blank plot. Assuming the data you plotted is stored in a variable data, the following code should do the sort of thing you want. http://www.merallelmath.org, available here.
