high-charts datalabel position needs to change whe

Question

Data labels (in this case cash) appear in the right place, just inside the bar on the right, most of the time. However if the value of the bar is low enough, it ends up overlapping with the axis label (as shown by the purple bar).

My first instinct was to set a max value and change the position of the data-label base on that. Something like, if value is less than $10 place the label outside just to the right of the bar. But there is a big problem with that approach. The size of the chart is variable and responsive, so that threshold needs to be variable.

Ideally the bar itself should be measured and compared with the width of the data label to determine position. Achieving that solution has me at a loss. I have had no luck in getting the phyiscal size of the bar out of high charts, or the datalabel for that matter.

Thanks in advance folks!

Answer 1

You can change X and Y position using attrin the High Charts.

By, Default data labels gets plotted outside the bar. So, I guess you should have set X and Y positions in the data Labels property.

You can do something like this

function(chartObj) {
    $.each(chartObj.series[0].data, function(i, point) {
        if(point.y <=10) {
            point.dataLabel.attr({x:point.dataLabel.x+30});
        }
    });

Call this method once chart is loaded.

Here is the fiddle link for the reference.

Can you try this,

var alignDataLabels = function() {
    var chartObj = window.chart || this;
    $.each(chartObj.series[0].data, function(i, point) {
        var dataLabel = point.dataLabel;
        // Get the current X
        var x = dataLabel.translateX;
        var y = dataLabel.translateY;
        // If the goes on LHS of the axis
        if (x < 0) {
            // Set the label's X to 5 px more than the bar's height(length) in pixels
            dataLabel.translate(point.barH + 5, y);
        }
    });
};
