Scatter (2 dimensions) and Bubble charts (3 dimensions) are available in StoryTeller which makes it possible to show even more data in single charts. The dynamic setup procedure makes it possible to cross variables of any type (mean, numeric and categorical.)
Here are some examples of these types of charts. In first example a top 2 box of brand familiarity (multiple questions) crossed with Awareness (single question and multiple answer alternatives) in a Scatter chart. The data point explanations are shown in the legend and circles used as symbols.
In the following chart it's the same example but the legend is shown in the chart. Square symbols are used for all brands except one.
In third example you'll see a bubble chart. The explanation text is shown in the legend and circles used as marks.
And the last example shows the same bubble chart, but squares are used as marks in the chart.
As shown in the example images above, variables of different types can be crossed with each other, for instance mean value variables can be crossed with categorical variables.
How to set up a scatter chart?
A scatter chart requires 2 data series in the chart, one for X and one for Y axis. The “Main series” in the chart acts as X axis and the “Sub series 1” acts as Y axis. So prior to adjusting settings you need to create two data series, the main which you probably already have and sub series, as shown in the image below.
How to set up a bubble chart?
A Bubble chart requires a third series as well for the Z value. When selecting Scatter or Bubble in the chart setup a new Tab will be shown in the setup interface named “Custom chart settings”, see the image below. In this chart the mapping between variables is done as each variable in the X- axis must be mapped to a variable on the Y axis (and Z in the Bubble chart). The image shows the Custom chart settings Tab and the settings are described further down.
The following steps are performed in the Custom chart setting Tab;
1. Map variables
2. Define labels
3. Define Symbols
4. Define Colors
The image below highlights the mapping area.
The labels shown in the Scatter/Bubble are picked from the X axis variables as a default. The labels can be picked from Y and Z axis as well by clicking the “Use as labels” button (highlighted in image below). The labels can be freely defined as well, just enter the desired text in the “Labels in chart” column. The image below highlights the label setup.
As shown in the example charts below, the explanation text of each data point can be shown in the legend or within the chart area. Though, no smart labelling exists, so if the texts are placed within the chart area it might be hard to read the text if the data points are too close to each other. The image below highlights the mark/symbol setup.
Colors can either be defined manually (per data point) or automatically be picked from the variables used in the X or Y (or Z) axis. To set the colors use the selection list shown in the image below.
Note: Scatter and Bubble Charts do not support the following features:
- Warn for low base
- Hide result with low base
- Show Top/Bottom X series (Top lists etc)
- Time intervals-only Full period can be used, Day, week, Month, Quarter and Year cannot be selected
- Significance testing
- In Hierarchical Filter projects unit comparison cannot be done. Only one unit at the time can be shown in the Bubble/Scatter.
