plot functions

[Winnok H. De Vos]

Dear all

A small question on plotting values in imageJ. Is there a possibility of
adding labels to the plotted points (at the markers)?
Thanks in advance.
Kind regards,
winnok

Hi Winnok,

if you are writing a plugin (not a macro), you could use
   myPlot.addLabel(double x, double y, String label)
you have to scale x and y however, addLabel expects coordinates
between 0 and 1.
   x = (xdata-xmin)/(xmax-xmin);
and the same for y, where xmax, xmin is the data range of the
plot and xdata is the x-coordinate where you want the label.

To get xmin, xmax, ymin, ymax you could use
   ij.util.Tools.getMinMax(data)
with the data arrays that you submit to the plot function.

Hello Michael,

Thanks for your reply.
I am working with macro scripting. But, come to think of it, I could use the
Plot.addText command in an analogous way you described (coordinates
relatively scaled), although this seems a bit tedious. There is no direct
macro command for labeling data points?
Regards,

winnok
