### Description

The line graph allows visualization of a datatable (by using a dataclip) on a dashboard. The control allows using a legend for data related explanations.

***

### Mappings

This control supports the following data related properties.

<table data-header-hidden><thead><tr><th width="162"></th><th></th></tr></thead><tbody><tr><td>Property </td><td>Note </td></tr><tr><td>Reference </td><td><p>Effectively delimits the shown data to a single column or row of a dataclip </p><p> </p><p>Usability of this mapping depends heavily on the linked fields </p></td></tr><tr><td>Segments </td><td><p>Effectively determines the pie segments that are displayed in the chart. </p><p> </p><p>Usability of this mapping depends heavily on the linked fields </p></td></tr></tbody></table>

### Default chart &#x20;

By default a chart will show table header as individual segments for a dynamic row. In most default situations the piechart needs to apply a row based filter to filter down a single row. The showed labels for each segment, by default, will show the unique values (occurrence) for each row, in most cases this value is not display friendly, to solve this an extended mapping can be made.

### Swapped charts

By default a chart will show table header as individual segments for a dynamic row. In some cases the reverse is needed, meaning a set of column values determine the segments.
