Neat and potentially useful data vis but copy like this makes me barf: “Bullet charts have proven to be ideally suited for any business dashboard data visualization.”
Proven? How? By what standard or metric? And for any business dashboard data vis? What does that even mean?
There is an example on creating a bullet chart in Excel. It starts with bar chart, which simple and easy to do and read. It then go through many steps to abstract and obscure some the information, to get to a chart that the author find more appealing. I don’t. I think a bar chart as more space and is more zen, while his chart feels crowded. Unless you start with only 3 bars, in which case it looks fine and doesn’t obstruct any information.
An unusual chart to convey simple information, and requires explanation, is a poor way to visualize your data. Only make a unique visualization if necessary to convey unique data. So, as you said, here just stick with the bar chart!
If it's ideally suited for everything then either it's a significant gain across the board and should be used in every situation ever, or it's got no particular advantage in any specific domain.
> To create a comparison range, you’ll have to pick a colour and make use of four different shades of colour. To help you do this, you’ll have to select the colours one after the other.
> Bear in mind that a bullet graph can either be horizontal or vertical in shape. As clearly mentioned above, the target of the organization must be feasible, and the right tools to reach the target should be provided for employees.
How did that last sentence end up in that paragraph?
Immediately below that, the final Excel output is unreadable: it shows the left axis scale ending at 450 and right axis scale ending at 400, with both values corresponding to the same grid line.
Below that, it says you can draw these charts in JavaScript with a <chart> element, as if browsers natively supported it.
