The Timeline Visualization requires a Date attribute for its X-Axis. It plots information to visualize when events took place. Each node shown in the timeline will be centered on the date/time value being for that record. A vertical red line shows the current date and time for reference.
Timeline configuration is broken out into four steps:
This step identifies the Date Field that will drive the Visualization.
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.
Timeline is based upon the concept of time, so this property is required in order for the Visualization to work. This field determines the X-Axis for the Visualization.
The input will only display attributes of type Date. If nothing appears in the drop-down, then there is no attribute of the appropriate data type that was found. Data from files are commonly brought in as STRINGs. An administrator can cast attributes to the appropriate data type using pipeline Transforms.
Point: single date field representing an event.
Range: two date fields representing an event duration.
Applicable only to item mode of point. This determines whether each Timeline item should be rendered inside a box or as transparent background without border. Set it to No if you only want to render each item as an icon.
Applicable only to item mode of range. This defines the end date of range’s duration.
Applicable only to item mode of range. If the rendered item content length is longer than the time duration block:
clip: item content is clipped
overflow: item content is flowed outside the block.
This step configures the attributes to display as part of each node in the Timeline. Each attribute has its own renderer, which determines how values for that attribute will appear in the end visualization. The process is identical to how list items are configured.
Selects an attribute from the underlying dataset.
Attribute Names can appear as labels inside of each node. This property allows you to override a dataset’s raw attribute name with something that is better suited for this particular display.
This property determines whether or not to display a label for the associated value.
This property determines how values for the specific attribute will be displayed inside each node on the Timeline.
See Renderers for more information about the options available with each renderer type.
The label formatter is a global setting for this Visualization. It applies to all of the labels that are displayed to the left of the values in each node.
Affects the colors of all labels.
Affects the size of all labels.
Affects the style of all labels (Bold, Italic, etc.).
This step determines the orientation and properties of the Timeline display.
Determines the orientation of the timeline axis.
Determines whether nodes are aligned to the top or bottom of the Timeline.
Determines whether dense collections of nodes can be offset along the Y-Axis for better visibility.
Determines the smallest zoom value that user can zoom down to. The input allows for numeric value, along with a pull-down containing units of measure for time:
Determines whether a Date slider control appears at the bottom of the visualization.
Determines the height of the slider control. Larger heights are typically used when “Show Sparkline” is enabled, giving more room to see the summary chart. This will cause the size of the footer element to grow.
Determines whether a Sparkline summary chart is displayed within the slider control area. The Sparkline aggregates data based on time intervals, and then displays counts based on a specified period of time.
This is only displayed when Show Sparkline is Yes. The aggregation method defined here will determine how values in the data are summarized on the Sparkline.
The bucket interval is used to aggregate records. Records are placed into buckets based on time stamps. The larger the bucket interval, the larger the bucket, which means they will each contain more records. Bucket Interval options include:
This step previews the end result based on the choices you made.
