Creating a "Stephen Few" bullet chart
Stephen Few designed the bullet chart as a replacement for a traditional gauge.
A traditional gauge takes up a large amount of space to encode, usually, only one value. A bullet chart is linear and can encode more than one value.
The main components of a bullet chart (from Stephen Few's perceptualedge.com) are as follows:
- A text label
- A quantitative scale along a single linear axis
- The featured measure
- One or two comparative measures (optional)
- From two to five ranges along the quantitative scale to declare the featured measure's qualitative state (optional)
There is no native bullet chart in QlikView. However, we can create one by combining a couple of objects.
Items 1, 2, 4, and 5 can be achieved with a linear gauge ...
