Line graph

The Line graph control visualizes a dataclip on a dashboard, with support for legends, data zooming, and a time-based axis.

Mapping	Description
XItems	The content shown on the X axis.
YItems	The content shown on the Y axis: the displayed lines.
YMin / YMax	The upper and lower bound of the displayed data, for a dynamic view of ranged data.

Usability of these mappings depends heavily on the fields you link to them.

Default chart

By default, the chart shows table header values on the Y axis as lines, and the unique row values on the X axis. Since the default X-axis labels just show each row’s occurrence, they’re often not very display-friendly: use an extended mapping to fix that.

Time charts

Linking the graph using a start and end date range automatically switches it to time-chart behavior, showing time-based values on the X axis. To make actual time gaps visible as gaps, enable Properties → Axes → Use time axis: the displayed time labels can still be formatted when this is enabled.

Swapped charts

In some cases you need the reverse of the default layout: the dataset’s rows determine the Y-axis lines, and the individual data points come from the table headers instead.

Events
