Introducing bar charts

In Highcharts, there are two ways to specify bar charts—setting the series type to 'bar' or setting the chart.inverted option to true with column series (also true for switching from bar to column). Switching between column and bar is simply a case of swapping the display orientation between the y and x axes; all the label rotations are still intact. Moreover, the actual configurations still remain in the x and y axes. To demonstrate this, we will use the previous example along with the inverted option set to true, as follows:

            chart: {
                .... ,
                type: 'column',
                inverted: true
            },

The preceding code snippet produces a bar graph, as follows:

The rotation of the country name and the logarithmic axis labels still remains the same. In fact, now the value labels are muddled together and the category names are not aligned properly with the bars. The next step is to reset the label orientations to restore the...
