Unless you’re working with dates, you can greatly improve the readability of the chart by sorting the series either ascending or descending. This applies mainly to bar/column charts.
…, such as a Streamgraph, but users shouldn’t have to learn how to read the chart you just invented. In most cases you should use one of the more common charts: area, bar/column, line, or pie/donut.
