Highcharts: Ensure y-Axis 0 value is at chart bottom

Question

I\'m outputting a series of highcharts on a page. In some instances, all data for the specified time period may come back with 0 values.

In such a case, the chart looks

Answer 1

Just add "min" option

yAxis: {
   min: 0
}

Answer 2

I had also posted this to the HighCharts forum, where I got a response that seems to work. Unfortunately, it will involve me doing some pre-processing of the data prior to rendering the charts in order to check for all "0" data values... but it'll work. Just wish there was something more "built-in" to HighCharts.

So after summing up the "y" values, if I get 0, the y-axis properties should look like this:

yAxis: {
    minPadding: 0, 
    maxPadding: 0,         
    min: 0, 
    max:1,
    showLastLabel:false,
    tickInterval:1,
    title: {
            text: ""
    }
}

See: http://jsfiddle.net/KM2Jx/2/

The keys seem to be the "max" and "showLastLabel" properties.
