Yes you can mix any series supported by a cartesian chart, just add the series and the chart wll handle it, charts are smart enough to scale according to the contained series.
|
||||
In this case we will only use ObservableClasses, so the chart updates automatically when a property changes, there are already some observable classes defined in thsi library, you
|
||||
can also build your own
