my scatter plot def:

dc.scatterPlot(theChart)
.group(tempGroup, "Temp (°C)")
.ordinalColors([tempColor]);

My chart def

var theChart = dc.compositeChart("#theChart")
theChart
.width(1180)
.height(420)
.dimension(timeDim)
.x(d3.time.scale().domain([startTime, endTime]))
.y(d3.scale.linear().domain([0,1]))
.xUnits(d3.time.second)
.brushOn(false)
.margins({top: 10, right: chartRightMargin, bottom: 30, left: chartLeftMargin})
.compose([lineA, lineB, tempLine, lineD])
.legend(dc.legend().x(1100).y(10))
.mouseZoomable(false)
.renderHorizontalGridLines(true)
.renderVerticalGridLines(true)
.xAxis();

The _locator function access coordinateGridMixin keyAccessor() an valueAccessor() to get the x and y translate, those appear to be coming back NaN. Is this coordinateGridMixin not valid for a scatter plot?
