The above is essentially the Several metrics per data point example from the Roassal book factored into two methods. Rather than just visualizing a static dataset I've been looking into ways of trying to add data as the program runs. I want to visualize the trace of the parameters for a tabular RL agent.
What happens when I display the graph in the inspector is that only the latest element shows up as a chart. There is some overlaying in the labels though that should not be there.
Originally I wanted to do something like pass an OrderedCollection of points, but the way RTVerticalMultipleData compiles them into Trachel elements makes such a scheme invalid, so I've thought to batch the data instead before adding it as an element.
The fact that the above does not work strikes me as a bug. Apart from fixing this, I am wondering if there is a better way to visualize dynamic data?
