Is it possible to add new data to a plot from a macro?

Dear all,
I am making certain measurements as i go through a macro and would like to
add these data to a single plot.
I am I correct in thinking that to create a plot and modify it all plot
commands must be in a single group?

For example this works
Plot.create("event profile", "Slice", "Intensity");
Plot.setLimits(0, nslices, gmin, gmax);
Plot.add("line",x, y);
Plot.show();

but if i then repopulate y

Plot.add("line",x, y);
Plot.show();

This will not work.

Is there a simple work around?

Thanks in advance,
James

Hi James,

You have to use Plot.show() at the end, after adding all data with
Plot.add().
Once shown, the graph can't be updated.

But, the ImageProcessor which is displaying the plot can be updated with a new Plot's data.

It might not be so simple for you to implement but that is the approach we took in BoneJ's Anisotropy plugin, which shows a live updating line plot with error bars and auto-scaling x axis. See createGraph() and updateGraph() here:

https://github.com/mdoube/BoneJ/blob/master/src/org/doube/bonej/Anisotropy.java#L365
https://github.com/mdoube/BoneJ/blob/master/src/org/doube/bonej/Anisotropy.java#L634

Not sure how you would do this in the macro language, however.

Awesome, I am now creating beautiful multi-colour graphs.
Much appreciated.
Do you know what the difference then is between
Plot.show();
Plot.update();
Cheers,

Thanks Michael,
If I ever move beyond macros, I am sure this will prove useful.
