The measurement points form a rectangular grid - in Labview I get a 2D array with the amount of counts from every measured point. To visualize the data I use an intensity graph like this one: http://cnx.org/resources/a8c66588021d0ead46885150c19c8340/intensitygraphexfp2.png Now I'd like to create a similar plot from the same data using Origin. I already know how to import data from Labview to a worksheet. What I'm struggling with is, how to create the plot, respectively which one I should choose. I found a video tutorial: https://www.youtube.com/watch?v=kSpGweGoXXw So I guess using a matrix and a contour plot somehow could work, but I would need a discrete value (in the shape of a rectangle) for every point of the grid without interpolation - how can I achieve this?
