how to set height and width of nvd3 chart

Question

I'm trying to set the width and height of a nvd3 multi bar chart programmatically using

chart.width(600);
chart.height(400);

See the example here:

As you can see this really messes up the chart. I know I can do this is CSS with:

#chart svg {
  width: 600px;
  height: 400px;
}

but I thought this was also possible using the width() and height() functions on the chart. Am I doing something wrong here or am I mis-using the two functions?

Answer 1

Yes it is possible, like you have specified the width & height of the chart, you have to use the d3.select and set its width & height attribute.

Changes to the code are below and there is a version of the code here

function visualizeData(data) {
    nv.addGraph(function() {
        var width = 600, height = 400;
        chart = nv.models.multiBarChart().x(function(d) {
            return d.x;
        }).y(function(d) {
            return d.y;
        }).color(['#aec7e8', '#7b94b5', '#486192']).stacked(true)
        //.margin({top:150,right:150,bottom:150,left:150})
        .width(width).height(height);

        chart.multibar.hideable(false);

        chart.xAxis.showMaxMin(true).tickFormat(d3.format(',f'));

        chart.yAxis.tickFormat(d3.format(',.1f'));

        d3.select('#chart svg').datum(data).transition().duration(500).call(chart).style({ 'width': width, 'height': height });

        nv.utils.windowResize(chart.update);

        return chart;
    });
}

For the AngularJs version (angular-nvd3), I had to add the height either in chart options and as an attribute:

chart.html

<nvd3 options='vm.chartOptions' data='vm.chartData' height="250" config="vm.chartConfig">
    </nvd3>

chart.controller.js

vm.chartOptions = {
    chart : {
        height : 250,
        type : "pieChart",
        donut : true,
        showLegend : false,
        //The rest of the configuration
};

As it is told in the comments, first seems to control the height of the inner svg and the second does the global chart height.
