Dynamic Y-Axis on Line Charts

The zoom slider is not available is you have multiple charts displayed for a line chart visual.

In line chart you can get mulitple charts in the canvas area by supplying another grouping measurement in the Small multiples field. What you end up with is multiple charts in the visual that have a common axis. The problem is that the Small Multiples field can have very disparate scales that make them unusable because the large scale will make the small scaled charts look like a flat line. See the inputs for the fields and formats

Please notice the grid layout that now appears where the zoom slide would appear for a single chart

The chart with values in the Millions complete skews the axis for the chart with values in the 10s

I would be nice to use the function on the y-scale to use the min and max of the individual chart and not the min and max of the overall data. The min and max should be determined by the small multiples grouping value.
