How can I programatically select a point in a Line Chart?

[palkatap]

I have a series of Line Charts (with the same number of points), and whenever I click on a point in a chart, I want to synchronize other charts (see https://github.com/palkatap/flutter_monitor).
How can I do this?

You would have to listen to the selection of the first chart and write a chart behavior that changes the value of the chart.

Listening to the chart is fairly simple:

However, we don't have a behavior that changes the selection of the chart other than the initial selection.
https://google.github.io/charts/flutter/example/behaviors/initial_selection

You could use that code as a jumping point to write your own behavior.

@palkatap - did you achieve setting selection programatically? I have (almost) identical issue - #208 and I would appreciate if you can help me with...
