Extension of Plot.add method

[CARL Philippe (LBP)]

Dear all,

For some applications I would need to have a Plot. add(java.lang.String
shape, double[] x, double[] y, , double[] z) method.

The idea is that this kind of plots gives a XY scatter plot where the Z
parameter is represented with a color coding applied on the shapes used for
the plot.

Which means either a grayscale levels coding or a color (I thought about the
Fire LUT) coding (thus the method could maybe even be declined by Plot.
add(java.lang.String shape, double[] x, double[] y, , double[] z, String
lut)).

Thus has somebody already done something similar (since it would be quite
stupid to reinvent the wheel if it is already made)?

Also as I see more or less how to modify the gray scaling of the shapes how
could I make their color follow a given LUT?

Finally (probably it is up to Wayne to answer this) once completed could
such a method be of common interest in order to be added within the native
methods of ImageJ?

I look forward for your answers and suggestions.

My best regards,

Philippe

Hi Philippe,

maybe you can sort the data into a few bins for the different z values and then plot each bin with a different color?

In the BAR suite (http://imagej.net/BAR) there is a script that fits a series of polynomials to a X,Y dataset.
The series of fits is colored according to a rainbow LUT, so you may find it useful.

There is an example here:
https://github.com/tferr/Scripts/blob/master/Data_Analysis/README.md#fit-polynomial

The source (with some annotations) is at:
https://github.com/tferr/Scripts/blob/master/Data_Analysis/Fit_Polynomial.bsh

Does it help?

Dear Michael and Tiago,
Thanks a lot for your answers and I will inspire from both of you.
Sometimes you are blinded by an idea so that you are missing much easier
ones.
My best regards,
Philippe
