Is this a bug, or do I not understand chart.ymax?

It seems to be impossible to get a line chart with a _fixed_ vertical scale of 0.0 to 1.0.

Setting chart.ymax to 1 (or 1.0, or 0.9999, or 1.1) results in a chart with y-axis values labeled as ["0", "0", "1", "1", "1"] (That is, as the result of integer rounding of the interpolated fractional values). Note that the line chart itself is drawn correctly, it's just that the labels are messed up.

Experimenting with ymax values greater than 1, the labels come out how you'd expect, which is what leads me to think this might be a bug.

Either way how can I force a line chart to have a scale of 0.0 to 1.0, and labels of "0.2", "0.4", ..., "1.0"?

Never mind. I figured it out:

myChart.set('chart.scale.decimals', 1)
myChart.set('chart.ymax')
