Gauge charts are a great way to display single values. By defining color intervals in your gauge charts, you can display zones within the gauge (like 'bad', 'average', and 'good'). For example, let's say that you have a course evaluation survey where you ask "How satisfied were you with the course?" and you want to display it as a gauge, it would look like this:
By adding color intervals, you can create the above zones so that your chart looks more like this:
To add color intervals, you have to:
- Click on the title of your chart to edit its settings.
- Enable the add intervals settings.
- Insert the number of intervals. For this example, we are adding 3 intervals.
- Define your intervals with a value. Interval 1 must be larger than the lowest value, interval 2 needs to be larger than interval 3, etc. Your last interval must be equal to or smaller than the largest value. In this example, the interval values look like this:
- Interval 1: 3. The question has a scale of 1 to 7, meaning 1 is the lowest value. This means that the first interval is from 1 to 3.
- Interval 2: 5. This means that the second interval is from 3 to 5.
- Interval 3: 7. The last value is 7. This means that the last interval is from 5 to 7.
- Now you can play around with the color theme for your intervals. Since this example displays a "bad", "neutral", and "good" zone, we have chosen the default color theme called "Net Promoter Score (NPS)"
