I will give a summary of the problem first, and then some more details for those, who would like to reproduce my problem. Problem: ======== I refer to Origin 6.0 and 6.1. I have got an image matrix with a resolution of 64x64 dots to be plotted as a contour plot. Each time I try the contour plot, I get a diagram with an axis range of (1..10) x (1..10) units (s. below for steps to this diagram). So the original resolution information of the image matrix are not obvious at the diagram scale. Even worse, if I rescaled the diagram axis by a factor 10/64 (s. below: will restore original resolution 64x64 to scale), the grapics ended at 64 correctly, but started only at 6.4. Here's the question: ==================== How can I create a contour plot with the correct scale axis range (i.e. 1..64 x 1..64) and without any such distortions. Best regards & thanks in advance A.Krause ===================================================================== How I created the contour plot: =============================== I think it should work like this with a squared matrix of any size, just fill it with any positive values and adopt the scale values afterwards... my Source: 64x64 matrix object select in menu: Plot3D -> Contour-Colour Fill both scales should now have the range 1..10 How I rescaled the contour plot: ================================ Right klick on the Y-axis, choose: Properties select tab "Tick Labels" for left- and bottom-axis do set "Divide By Factor"=0.15625 (= 10/64) press "Apply"-button select tab "Scale" for horizontal- and vertical-axis do set "From" = 1 "To" =64 "Increment"= 8 press "OK"-button Now you should have the correct resolution showing at the axis, but the graphics will start only at 6.4 while between 1..6.4 should be a white area now. That is why the former starting point (=1) has also been rescaled by factor 6.4. I think some kind of scale offset could help here, but I could not find such option...
