FunnelSeries2D.HeightToWidthRatio Property

Gets or sets a value that specifies the height-to-width ratio of a Funnel Series series.

Namespace: DevExpress.Xpf.Charts

Assembly: DevExpress.Xpf.Charts.v18.2.dll

Declaration

C#

public double HeightToWidthRatio { get; set; }

VB.NET

Public Property HeightToWidthRatio As Double

Property Value

Type	Description
Double	A double value that specifies the height-to-width ratio of a funnel.

Remarks

Use the HeightToWidthRatio property to manually set the height-to-width ratio of a Funnel series. To enable auto-calculation of this ratio, use the FunnelSeries2D.HeightToWidthRatioAuto property.

The following images demonstrate the HeightToWidthRatio property in action.

HeightToWidthRatioAuto = true	HeightToWidthRatioAuto = false HeightToWidthRatio = 2

Example

The following example demonstrates how to create a 2D Funnel chart.

For this, it’s necessary to create a ChartControl, choose a SimpleDiagram2D object as its diagram and put FunnelSeries2D into its SeriesCollection. Each point of a funnel series should contain an argument and a value.

Note that in this sample the label’s SeriesLabel.TextPattern and Series.LegendTextPattern properties are set to “{}{A}: {VP: ##.##%}”, which allows showing a point’s argument and its percentage value separated by a colon. The available placeholders are detailed below.

• {A} - Use it to display a series point’s arguments.
• {VP} - Use it to display a series point’s values as percent.
• {S} - Use it to display the series name.
