Tim, Your thinking about this is just fine. The explorer mode changes the viewWindow of the chart's axes, but these changes are not reflected in any internal state of the chart. Consequently, when you draw the chart again, the viewWindow changes are lost, and reset to the default, or whatever you specify in the options. This is arguably the correct thing to do.
But there is also no way to find out (like with an event) that the explorer mode has been used. You can, however, find out more indirectly where the viewWindow has ended up as, using the getChartLayoutInterface method and related methods: https://developers.google.com/chart/interactive/docs/gallery/linechart#Methods Unfortunately, this is not as easy as it ideally should be, so we need to fix that. Hope this helps. On Sat, Nov 22, 2014 at 10:15 PM, Tim Havens <[email protected]> wrote: > I'm probably thinking about this incorrectly.
