Hi,

There is a nice feature in Origin that takes a 2-column worksheet and makes 2D binning with color-coding proportionally to number of data in bins. Is it posible to do the same but to color-code with data from the 3th column - for instance to color-code with the average value (in bins) of the 3th column?

thanks
oliver

Hi oliver,

Plot the second column, open Plot Details and set Symbol Color to Indexing> Col(C) or Color Mapping> Col(C).

Not sure what you mean by "average of column C in corresponding bin" but I'm guessing that Color Mapping> col(C) is what you want.

how to say .... hmm ... I mean, to bin A(x), B(y) first. This is somthing I do in Origin with

Edit> Convert to Matrix > 2D Binning

Az a result I have a Matrix with number of data in bins. When I plot it, the color-coding is according to this numbers

I would like to do similar thing now like:

1. to bin A(x) and B(y) like above
2. to calculate average of C(y)in each bin
3. color-code NOT using the number of objects in bins BUT the calculated average from step 2.


What you suggest is to plot all data and color-code with the 3th column C(Y) no? But I would like to bine the data first and then to color-code with the average of C(y)s in bins.
