Would you mind pasting the code you use to assemble the google.visualization.Dashboard as well, if any?
I suspect you are using a google.visualization.Dashboard linking together the slider with the linechart, _and_ your own onControlStateChange callback. The former is geared toward performing row filtering (that's the way dashboards work by default), while your code performs the column filtering. The combination of the two is likely to generate the problem you describe. -- R.
