Charts

Whilst there are a variety of chart types, all charts have some common properties:

• Title
• Provider
• Label Column
• Data Column(s)
• Width & Height
• Margin
• Custom CSS
• Conditions

Providing data

Charts allow you to visualise data from a Data Provider, which can have datasources such as:

Label Column Provides the name of each categorical variable.
Data Column(s) Provides the value or range of values for each label.
