Hi,

I would like to ask why the contour plot graph did not appear when i plot the graph. Is it due to the readings?

I added data regarding excitation from 400nm to 800nm and emission data from 450nm to 800nm. The intensity results as Z.

Thanks in advance for those who can help me in this. =)

Hi happy54,

To create a contour plot from XYZ data, XY data points should be distributed on the plane randomly or regularly,
but your XY data seems spreading on a single line. That is the reason. Maybe what you wanted to make is a
"waterfall" plot, or its flattened version as shown here? http://blog.originlab.com/graphing/flatten-waterfall-plot

If so, you have to reorganize your data like in this sample.

I hope I didn't misunderstand what you wanted to achieve.

Hi Hideo Fujii,

I am trying to achieve something like this picture I posted


I am trying to draw excitation and emission wavelength contour plot. Thanks for your suggestion. I will look into XY to see how I can make the data into regular data.

Thanks.
