I have about a days work left and the plot is ok. The performance issue means I have limitations, but for most applications this will be more than ok. More important is that coding up the rest of the plot is about re-using components from the linear bar. I need to modify range to support time and to auto-scroll with the plot(s). I will add a simulator function allowing designers to see example data in the plot.
And then comes the more difficult issue – user controls on the plot. I will add the components separately for those who want to build their own custom plots, but I will also add a few standard ones. Stay tuned.
