Hello,
I use Labview to measure the element distribution in certain points of surfaces. 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:

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:

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? |

Thanks a lot,
I think that is what I need - so far I only have access to Origin9, that's why I didn't see this option. I should get a new license with Origin 2015 soon (in case someone is curious - Heat maps are only supported since Version 2015). |

Hi,
What you want is a graph type called Heat Map. Since Origin 2015, you can make such graph by going to menu Plot: Contour/Heat Map: Heat Map to make one.
Below is an example to show the data structure and heat map:
See if this is what you need.
Regards!
