How do you interpret the bar graph?
For list questions, the bar graph is the easiest graph type to use and it is also set as default when you add a list question to a board (learn more about how to change graph type here). By using the bar graph, you get a quick overview of the distribution of the responses:
The alternative with the most responses have the longest bar, and they get shorter in descending order. If an alternative is not showing, it is because there are no responses for that alternative. You can add alternatives without responses by clicking the "dit" button in the top right corner of the card, and then selecting "show rows without result":
If you hover the cursor above a bar, you can see an internal benchmark:
In the example above, the Stockholm office (which the card is filtered on) has 74.9.2% answering "Yes, via e-mail" on the question, while the company average for that response is 74.4%. You can also see how many responses there are.
