Hi all,
I am thinking about a specific setting where I want to make a scatterplot that is somewhat
dynamic: I have collections of points coming in regularly and when a new collection has
arrived I want to remove the existing plot and show the new data. I thought I would be
able to do something with the existing Grapher infrastructure. My idea was to remove all
elements from the open RTView instance, then remove the dataset from the RTGrapher
instance, add the new dataset to the RTGrapher instance and call build again. But I cannot
remove a dataset from a RTGrapher, so apparently no go.
Is there a way to do something like this without making modifications to Roassal? I could
hack something together of course but prefer existing infrastructure, if present.
Also, I want to set max X and max Y beforehand because I know what the range of the
incoming points is.
Any pointers would be appreciated!

RTGrapher has not been designed for dynamically update.
However, this is an easy problem to solve. Currently, I have no idea whether the current
infrastructure can support this or not. So, I am inclined to build something from scratch
(i.e., a new builder).
But first, tell me more about your need. You need a scatterplot? Or you need a curve? If
you need a curve, then how many datapoint you need to have?
Cheers,
Alexandre

Cool :-)
I just need a scatterplot. Data will be a RTStackedDataSet, of always the same number of
points, and I know this number in advance. I know what min and max Y will be. I would like
to be able to set ticks at specific places at the X and Y axis, but if that is not
possible a number of ticks is OK **if** I can guarantee that one will be set at the median
of X. In Y this is not so important right now.
PS: It’s for robots! ;-)

I would like to have something similar for sensors outputs ;-)

You people are getting more and more demanding! :)
@Alex et co: it's all your fault because you keep teasing our imagination

Thanks everyone. These are exciting times.

Hi Johan!
We have produced the class RTDynamicGrapher. You can dynamically add elements. Here is a
try:
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
b := RTDynamicGrapher new.
b maxX: 100.
b maxY: 100.
b x: #x; y: #y.
b shape circle color: (Color red alpha: 0.3).
b view addMenu: '+ 10' callback: [
b addAll: ((1 to: 10) collect: [ :i | (100 atRandom @ 100 atRandom) ]) ].
^ b
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
Once you have set your instance of RTDynamicGrapher, then you can use #add:, #addAll: to
add elements. You can also change the shape if necessary.
I believe this should completely fulfill your requirements :-)
Cheers,
Alexandre

That’s great, thanks!
But … it does not fulfill my requirements. I need to be able to remove all of the drawn
points as well, the new data completely replaces the old data. Could you guys have a look
at that?
Thanks in advance :-)
