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

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!
