I need to increase the size of columns width in my Chart. Does anyone know if this is possible?
The Charts are responsive. Can you place your chart in a grid with a minimum size? This will make the bars larger.
If you have limited screen real estate, then you can consult the Highcharts API documentation (http://api.highcharts.com/highcharts). It looks like ‘pointWidth’ is what you want to set via a Before Render Snippet (http://api.highcharts.com/highcharts/plotOptions.bar.pointWidth).
