Check out the GDP chart under “The New Triad” here:
It’s supposed to compare GDP in China, India, and the US for three time periods but for my money, it’s composed wrong. The bars should be for the years, not the countries. That way we could see total GDP in each year and how it was composed of the respective GDPs. It would even be fairly easy to scan across and see how the country’s GDP grew or shrank. What’s there is just confusing.
I agree. Better to put time on the x-axis if possible. Then you don’t need a bar plot at all, you can use a line plot, which I generally prefer.
