Visit dygraphs.com/tests/demo.html on an iPad and tap the chart. Nothing happens.

There's a pull request which addresses this: #244 Calling "g.mouseMove_(event)" in touchstart also fixes the issue but has the downside of generating select events even when the chart is being panned.

The ideal solution would check if the touch ever moved in touchend and do the selection there if it didn't. This would be analogous to the way we distinguish click/drag and click.
