Introducing column charts

The difference between column and bar charts is trivial. The data in column charts is aligned vertically whereas it is aligned horizontally in bar charts. Column and bar charts are generally used for plotting data with categories along the x axis. In this section we are going to demonstrate plotting column charts. The dataset we are going to use is offered by the U.S. Patent and Trademark Office. The graph just after the following code snippet shows a column chart for the number of patents granted to the United Kingdom for the last 10 years. The following is the chart configuration code:

            chart: {
                renderTo: 'container',
                type: 'column',
                borderWidth: 1
            },
            title: {
                text: 'Number of Patents Granted',
            },
            credits: { 
               position: {
                  align: 'left',
                  x: 20
               },
