Highcharts vertical stacked bar chart with negativ

问题:

Is it at all possible to be able to have a vertically stacked bar chart with negative values (using highcharts).

Like this: http://jsfiddle.net/gh/get/jquery/1.9.1/highslide-software/highcharts.com/tree/master/samples/highcharts/demo/column-stacked/

        series: [{
            name: 'John',
            data: [5, -3, 4, 7, 2]
        }, {
            name: 'Jane',
            data: [2, 2, -31, 2, 1]
        }, {
            name: 'Joe',
            data: [3, 4, 4, 2, 5]
        }]

Unfortunately negative values don't register.

This seems to be a solution: http://jsfiddle.net/gh/get/jquery/1.9.1/highslide-software/highcharts.com/tree/master/samples/highcharts/demo/bar-negative-stack/

But for visual reasons I need the bars to be vertical.

Any thoughts on a fix would be greatly appreciated!

Thanks,

Tom

I was trying to achieve the same results. Check this fiddle and let me know =] I used:

chart: {
    type: 'column'
},
plotOptions: {
    series: {
        stacking: 'normal'
    }
}

EDIT: try changing the type to 'bar'. This will make the chart "columns" go horizontal =]

The Highcharts demo code for a 'Stacked column' does not work for negative values for the simple reason that the y-axis range is limited in the example code. The answer lies in removing the min=0 argument from the yAxis options.

The yAxis options should read

    yAxis: {
        title: {
            text: 'Total fruit consumption'
        },
        stackLabels: {
            enabled: true,
            style: {
                fontWeight: 'bold',
                color: (Highcharts.theme && Highcharts.theme.textColor) || 'gray'
            }
        }
    }

With these options in place the example code for the 'Stacked Column' chart will display negative values correctly.

You can use stacked column and then set inverted parameter as true, then chart will be rotated.
