Sorry if there is already a thread for this, but I cannot find one.
I am trying to make a contour plot where each pixel contains two values. One will be linked to a colormap (i.e. parula, so that high values will be yellow and low values blue). The second value will be related to the darkness of the pixel (i.e. 1 = pixel is black, 0 = pixel is the parula color, 0.5 = dark version of the parula color). Is there a way to make this contour plot in Origin?
Thanks for any help! |

Could you make a black-white contour and uses it as a mask? Then merge the original contour plot and the mask contour plot (menu Graph->Merge Graph Windows). See the attached project file.

Yes, here are the two matrices. One should have values from -90 to 90. The other should be from 0 to 1. So, all of the 0's in the upperMatrix would be black and all the rest would be the parula colormap with varying darknesses.

Origin doesn't have the option to map darkness to a matrix. However, if the data contains only three values for darkness, a possible workaround could be to split the matrix into three separate matrices and then create a contour plot for each matrix using a different color palette. Finally, the three matrices can be merged together to form the complete plot (Stack the three contour layers). Could you share some sample data? Thank you.
