Click the Bubble chart icon
...
to visualise your data as a bubble chart. A Bubble chart is essentially the same as a scatter plot, in that you
...
can take two metrics (One on the Y-Axis and one on the X-Axis) and see if there is a relationship between them. However, unlike Scatter plots, the Bubble chart features an extra measure called Measure (Size) which determines the size of each bubble on the chart.
...
...
Example
In the example below, this bubble chart plot is being used to show if there is a relationship between
...
the number of questions in an assessment and the number of users completing an assessment, and whether or not this affects the pass rate.
...
Hovering over each bubble on the chart reveals details, such as the assessment ID, the number of questions in the assessment, assessment completion rate, and the number of users who have passed the assessment.
...
To recreate this example:
Drag the Number of Questions
...
in Assessment measure from the
...
Data Catalogue, into the Measure (X-axis) section. This section displays a measure on the Y-axis of the scatter plot.
...
Drag the Assessment Completion Rate measure from the Data Catalogue, into
...
the Measure (Y-axis) section. This section displays a measure on the X-axis of the scatter plot.
...
Drag the Assessment Id
...
attribute from the Data Catalogue, into the View By section. This section is used to display an attribute. This attribute determines the meaning of each point in the scatter plot.
...
Drag the Number of Users
...
Passed the Assessment measure into the Measure (Size) section. This section is used to determine the size of each bubble on the chart. If a bubble on the chart is larger, it means there is a higher number of users passing the assessment and if the bubble is smaller, less users are passing.
...
Drag the Assessment Type attribute from the Data Catalogue, into the
...
Filters section above the chart.
