Annotations and Sub-graph ?

[pravin-d]

This is two part question. Both of them are related to my use case

1. Does fl_charts support point annotations ? If yes, would be able to make it clickable ?
   Use case:
   Lets say I have a graph of todays temperature. I would want to mark events like heavy rain, etc on the x-axis(time axis). When I click the annotation, it should give me a popup showing some details of the event.
2. Can I have another chart below the actual chart. Use case is same as above, except I would put the annotation in the sub-graph.

A good sample would be -> Please replace the candle sticks with a simple line graph
The main graph and the volume graph are in separate panels but have a common x-axis.
There an event annotation which when click shows a popup

We've something similar for annotations (but not exactly what you want). It doesn't support touch callbacks yet.

You can take a look at LineChartSample8 in our line-chart-samples

About your second question, yes you can hide the titles and put the charts in a Column to show them. Don't forget to provide a height for them, because fl_chart doesn't provide a height for you. (You can use AspectRatio too)
