Control of chart animation #27

Closed rubberbird closed 5 years ago

It would be great to have the ability to control the animation of the data being written to the charts. For example a line graph that would draw temperature in realtime while the use is watching it.

If you are using a stateful flutter widget, you should be able to maintain the data in your state and update it inside flutter's setState. The chart should animate to the new values you provide. Is this what you mean?

Hello, @thekeenant, first of all, thank you for your work! Probably not what the author meant, but let me elaborate on this issue: is there a way to control animation duration? Let's say I use LineChart, and I feed new data every second. I want the animation to go slow, and smooth so it doesn't seem like it stops between states, for that I would need to control animation time.

@thekeenant Just to clarify, I mean animation which happens on changing DoubleSpan.
