Hi, I am trying to draw a 2D contour plot in Excel. I have attached my data and the color contour I am expecting to draw (I used another software for drawing this contour: Origin). TIA

Unfortunately that type of chart is not easy to make in Excel as it requires your x and y data to be spaced with the same gap between each set of two points, so for example:
x: 1,2,3,4,5
y: 2,4,6,8,10
I see. Thanks, Jan.
