Sample Description

How to use this sample?

Change visible range using chart scroller, presets picker or via chart drag to get onSelectedRangeChange event and retrieve Y-axes information

to top

How it works

AnyChart Stock offers a number of ways to change range shown on the chart: using chart scroller, presets picker or chart drag. Every time the shown range changes, Y-axis scale is recalculated and onSelectedRangeChange event is fired. This event handling allows to call getCurrentYAxisInfo each time the scale is recalculated. And the getCurrentYAxisInfo method allows to get recalculated Y-axis info.

This sample shows how to use getCurrentYAxisInfo method to get Y-axis info.
