Concept: Chart Viz Mark Types
In a Chart visualization, Workday displays the data as a collection of marks. A mark is
the visual representation of a metric value calculated for a group of input rows.
The mark type controls the shape of data in a Chart viz, and how data points are visually
represented. When you create a Chart viz in a discovery board, you can select the mark
type from the
Marks
drop-down menu.How Workday renders a particular chart depends on the mark type along with the placements of
summarization and attribute fields in the drop zones.
Mark Type | Description |
|---|---|
Bar | Workday displays each mark as a rectangular bar with its length proportional to the
value it represents. |
Point | Workday displays each mark as a dot, with its position determined by the values on the
2 axes (Cartesian coordinates). |
Line | Workday displays each mark as an end point of a straight line, with a straight line
connected between marks. You might use a line chart to visualize a trend in
summarization data over time with the line drawn
chronologically. |
Area | Like a line chart, Workday displays each mark as an end point of a straight line, but
fills the space between the marks and the horizontal axis with a
color. Similar to a line chart, an area chart typically displays
summarization data over time, and is typically used to compare 2 or more
quantities. However, unlike lines, area charts are typically used to
represent cumulative totals rather than individual totals. You might
use an area chart to illustrate how the member of an attribute contributes
to an overall trend. |
Auto | Workday selects the best mark type based on the fields in the drop zones. |
