Negative Y Axis when data series is all zero

Hi,

if there some way to not show negative y-axis values when the data series is all set to zero?

I have tried setting

ticks: {
    beginAtZero:true,
    min: 0
}

for the y-axis scale but it doesn’t appear to do the trick.

$scope.chart_line_options = {
                scales: {
                    yAxes: [
                        {
                            id: 'y-axis-1',
                            type: 'linear',
                            display: true,
                            position: 'left',
                            ticks: {
                                beginAtZero: true
                            }
                        }
                    ]
                }
            };
