In the previous post, we showed a gallery of various area charts. In today's post, we'll see some examples of bar charts.
Bar charts use separated bars to render each data value. Negative values can optionally be rendered using an alternate style. High and low values can be highlighted. Multiple bar series can be rendered in the same chart and there are options to determine bar spacing and the bar orientation.
When rendering multiple bar series in a chart, you can set the bars to "stack", similar to how area chart stacking works. In this case the second series renders its values on top of the first series' values. This gives a good comparison of data between the two series.
Another option is for the series to stack 100%. In this mode, the series render to fill the chart height. At any given X-coordinate, the height of each rendered series indicates its value percentage relative to the total.
In the next post, we'll look at some scatter charts.
