Solid Gauge is chart type available in StoryTeller. The main purpose of the Solid Gauge is to show KPI’s and similar values appealingly. The solid Gauge is a mix of a Gauge and a Donut. Below are a few examples of the Solid Gauge. As you can see, multiple series’ can be shown, but the value in the centre of the Solid Gauge can only be shown if the Solid Gauge shows one series.

With the Solid Gauge, there are a few limitations when compared to a normal line/column chart.

  • The series in a Solid Gauge can be Stacked or Full Staked. They cannot be side by side.
  • The following functions cannot be used: The “Analysis” functions Significance testing, Mean value series, and Percentiles.
  • The sorting of series’ is not supported, like in the normal Gauge chart.
  • A Solid Gauge always shows the “data value” in the centre of the chart, as you can see in the left chart below. If multiple series’ are shown, the value is not shown, as you can see in the right chart below. It uses the same logic as the normal Gauge.

How to create a solid gauge?

To create a Solid Gauge, select it from the ordinary chart selection list. Once you’ve selected the Solid Gauge, all items such as answers, questions, compare filters, time intervals, etc are automatically shown in the Legend. To define the shape of the Solid Gauge, select Gauge from the Layout tab, as shown in the image below. Use the ‘Start Angle’ and ‘End Angle’ to define the shape, from 0 to 360. You can see examples of different shapes in the second image below. The image below shows the special Gauge layout settings.

The charts below show a few different start and end angles.

Use the “Inner Radius” setting to define the thickness of the chart (see the setting in the setup image above).The two charts below show different inner radius settings.

In all examples above, the default behavior of the Solid Gauge is to start from 0 (and go to the actual result. If you work with negative numbers and would like to have the chart started from a minimum for example negative value, this can be achieved by changing the Threshold value function (from 0 to a negative number), with this function you can set the start point to for example -100. 


Note: when creating a new gauge, the items are sorted clockwise and at the same time following the sorting in the legend. This logic is applied to newly created Solid gauges only, existing Solid gauges are still sorted as before.

Here we see two solid gauges; the right gauge shows the old sorting and the left the new sorting. As shown the items in the 

left gauge are now following the legend order (the new logic).
