A Small Multiples Visualization compares values over a normalized time period, so this Visualization requires a Date Attribute for its X-Axis. It then stacks a series of charts on top of one another, so that the information can be compared.
Small Multiples supports series information stored as values in a single column. In this structure, the series will be derived from unique values within the specified attribute (shown in red).
Small Multiples also supports series information stored as individual attribute names (shown in red)
Small Multiples data should be sorted by date (x-axis attribute). If it is not sorted by the x-axis attribute, then the d3 component will not generate its mouseover redline that helps compare values across all the charts based on the date.
Configuration of the Small Multiples Visualization is broken out into four steps:
This step defines the data structure and other basic properties.
A symbolic name used to represent this Visualization. This is the name that will show up in choosers when adding a Visualization to a page.
Determines how series information should be parsed from the underlying dataset.
(Applicable to Single Column data structure) This property requires you to select the attribute which contains series names. The Visualization assumes these names are STRINGs, so a STRING attribute is required. The unique values for this attribute will be rendered as individual rows within the Visualization.
(Applicable to Single Column data structure) This property requires you to select the attribute containing values for the series. The Visualization assumes these values are NUMBERs, and will plot these values over a normalized time period.
This property is limited to attributes of type DATE. It requires you to select the date field that will be used to determine the time range to use for the Visualization.
This step will change based upon the data parsing options that you selected in step one above.
This property determines whether the series information is manually defined, or should be derived based on what is in the data.
After selecting the Dynamic Series option, there are four different possibilities based upon the combination of Data Structure and Series Type:
This property provides additional ways to limit the series information that will be displayed, based on STRING rules.
This property only appears when the “All Unique Values” option is selected. This option allows a user to specify Attribute Names to exclude from the Visualization. This is typically used for attributes containing numeric IDs, which do not make sense to plot within the Visualization. All of the possible columns/values are shown in a pull-down list by clicking on the input field.
This pull-down allows you to select from a list of valid Attribute Names.
This is an optional text input that allows you to override the raw Attribute Name coming in from the data with a label that is more human readable.
This property allows you to toggle between the raw Attribute Name and the label override.
The Multiple Column Dynamic Series is already limited to Attributes of type INT. It will ignore all STRING and DATE Attributes when deriving the series. The series rules here provide some additional ways to limit attributes based on naming conventions.
This property only appears when the “All Columns” option is selected. This option allows a user to specify Attribute Names to exclude from the Visualization. This is typically used for attributes containing numeric IDs, which do not make sense to plot within the Visualization. All of the possible columns/values are shown in a pull-down list by clicking on the input field.
The renderer configured here for Small Multiples is applied to all of the charts in this Visualization.
The charts used in this Visualization are minimalistic in nature. They are designed with comparison in mind, and do not show a lot of detail in terms of axis labels.
Color applied to all of the charts.
Color of a chart on mouse over.
Width of the line for both Line and Area chart types.
Determines the height for each chart.
Color of the Series label, which appears as an overlay at the left hand side of each chart in the Visualization.
Size of the Series label.
Style (bold/italic) of the Series label.
This step previews the end result based on the choices you made.
