    I can't seem to get the selection event to work on an iPad. Your Master-detail demo isn't working with an iPad either.

    Hi Torstein, I couldn't find any info about this in the release notes to the newest release - has it been incorporated?

    I need users to be able to zoom into a chart, pan around and then make multiple selections for section of data to be analyzed. I'm successfully using plot bands for making the selection based on the selection events, so I need a separate mechanism for zooming and panning.

    It is still under development.

    Technically you don't need it for selecting a range, you already have the chart.events.selection event for that. It currently works by dragging the finger across the chart.

    This is listed on the current Roadmap ("Implement pinch zooming and panning for touch devices and dont let single touch dragging move the tooltip."). http://www.highcharts.com/support/roadmap

    Do you have any details on the ETA? I'm right now evaluating Highcharts and being able to easily select a range of values from a chart is a core requirement for my application.
