multichart line starting points

[rjangid1]

I'm using multiline charts in my angular application and noticed that the starting point is sometimes inconsistent.

chart options are

$scope.chartOptions =
            title: '',
            x_accessor: 'date'
            y_accessor: 'value'
            small_text: true
            legend: []
            legend_target: '.legend'
            area: false,
            aggregate_rollover: false
            full_width: true

This is likely a MetricsGraphics issue but I'm happy to look at it anyway. Can you post some sample data so that I can take a look at this?
