question about plot API

Aryeh Weiss
I have not been able to figure out how to plot connected markers, other
than circles. For example:

plt.addPoints(range(1,14), dsum, None, Plot.CONNECTED_CIRCLES, "Total
Area")

adds a trace to plt. However, in another line, I have

plt.addPoints(range(1,14),[x/tmp[0] for x in tmp], None,  i%8 , "Track
"+ str(i))

where I use i%8 to cycle through the various markers (CROSS, DOT,
TRIANGLE, etc).
and I would like to plot these connected, just like the connected
circles, but I cannot find the option to do that.

A second question is how to use the labels that are in the last argument
of the addPoints command. I would like to put them in the legend, but I
do not see how to recover them in order to add them to the addLegend
command.

Thanks in advance for any help on these issues.

Hi Aryeh,
Which class does the plt object that you created belong to?

Thanks,
Avital

Hi Avital

Thank you for your response.

Belongs to Plot  .  I found the following:

1. I can draw a second trace with addpoints, using Plot.LINE, which
gives the correct appearance, except that the legend will not include
the line.

2. I can get the label into the legend if I put a null string ("") in
Plot.addLegend(). So that question  is answered.

Best regards

Re: question about plot API

Hi Aryeh,

currently, the ImageJ Plot class only has CONNECTED_CIRCLES, no
CONNECTED_TRIANGLES, CONNECTED_CROSSES or so.
I don't think that connected dots would make much sense (the line would
hide the dots).  One could think of connected boxes or diamonds [oops, I
just see that we even don't have plain diamonds yet!]
Beyond ImageJ, I have seen much more plots with connected circles
compared to other connected symbols, so I consider this not too bad a
choice.
Also, the CONNECTED_CIRCLES are still not as nice as those of some other
plotting programs; I think it would be nicer to have the lines end just
outside the circles, not go all the way to the centers (if I have much
time, maybe I'll change this).  But what we have is better than nothing.


If you want, e.g., connected squares, you could plot the same data set
twice, once as squares (BOX), then as a line.

In any case, ImageJ is not a full-fledged plotting program; if you need
advanced plots you will still need Gnuplot, Grace, Veusz, etc, or the
expensive solution named Origin.
