Vue PieChart - commonSeriesSettings

Use this object's properties to set properties for all chart series at once.

When defining a series, set the argumentField property to the corresponding field from the data source.

By default, the series arguments have the same type as the values of a corresponding data source field. If the data source field values are numeric, the series arguments will also be numeric, etc. However, you can convert the data source values to another type. In this instance, specify the required type using the argumentType property.

To set custom border settings for the series, use the border object within the series configuration object.

Use this property to paint all pie slices in one color.

The following values are available.

• onlyPoint
  Changes the appearance of the hovered point only.
• none
  The appearance of the hovered series is not changed.

To set custom properties for the 'hover' style (which is applied when a series is hovered over), use the hoverStyle configuration object.

To set a custom 'hover' style for the series, use the hoverStyle object within the series configuration object.

Each series point can be accompanied by a text label that represents data related to the point. These are called series point labels. Use the label object's properties to set label properties for the series.

When there is a series with a large number of points, the point labels may overlap each other and make a chart difficult to read. In this instance, it is better to display the point labels depending on their quantity. To specify the maximum amount of the labels to be displayed, set the required number to the maxLabelCount field. If the number of the points on a series exceeded the number assigned to the maxLabelCount field, the point labels for this series will not be displayed.

When you visualize data with small and large numbers, the small numbers are represented by very small pie slices. It makes them difficult to click, select or hover over. In this case, use the minSegmentSize property to set the minimal size of a displayed pie segment.

The PieChart UI component comes with an API that allows you to select a series or a particular point in code. Use the selectionMode property to specify which series elements to select when the series is selected.

• onlyPoint
  Changes the appearance of the selected point only.
• none
  The appearance of the selected series is not changed.

To set custom properties for the 'selected' style (which is applied when a series is selected), use the selectionStyle configuration object.

The PieChart UI component comes with API members that allow you to select the series in code. To set a custom 'selected' style for the series, use the selectionStyle object within the series configuration object.

If you need to group specific chart segments into one, use the properties of the smallValuesGrouping configuration object.

You can group segments in two different modes. Use a 'topN' mode to group all segments that have an index that is equal to or greater than the value of the topCount property. To group all segments with the value less than the value of the threshold property, use a 'smallValueThreshold' mode.

By default, the resulting segment is called "others". To change this name, specify the groupName property.

When setting a data source, you can pass extra information about a point. For this purpose, add a separate field to the data source in addition to the argument and value fields. To set specified data to the point instance, set the series' tagField property to the name of the field with the information. In this instance, when clicking/hovering/selecting a point in the chart, you can access the data associated with this point using the point's instance.

When defining a series, set the valueField property to the corresponding field from the data source.
