Color Ranges in Gauge Charts

About Color Ranges in Gauge Charts

Frequency Charts can be displayed as gauges, which are a great way of visualizing single values, such as averages. By defining color ranges 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 respondents to evaluate their satisfaction with the course, and you want to display this as a gauge in your report, it would look like this:

By adding color ranges, you can create the above zones so that your chart looks more like this:

Add Color Ranges

To add color ranges, you have to:

1. Go to your report and click on the chart's heading to open the edit chart side menu.
2. Enable the add color ranges option.
3. Insert the number of ranges. For this example, we are adding 3 ranges.
4. Define your ranges by adding their end value. Range 1 must be larger than the lowest value, range 2 needs to be larger than range 1, range 3 must be larger than range 2, etc. Your last range must be equal to or smaller than the largest value. In this guide, for example, we have a chart based on a 5-point Rating Scale question and the range's end values look like this:
   1. Range 1: 3, which means the first color range is from 1 to 3.
   2. Range 2: 4, which means that the second color range is from 3 to 4.
   3. Range 3: 5, which means that the last color range is from 4 to 5.
5. Now you can play around with the color theme for your ranges. Since this example displays a 'bad', 'neutral', and 'good' zone, we have chosen the default color theme called 'Net Promoter Score (NPS)' to visualize these categories.
