Namespace: GlobFX.SwiffChartGenerator
Assembly: GlobFX.SwiffChartGenerator (in GlobFX.SwiffChartGenerator.dll)

Specifies the color for the trendline associated with a series defined by its index in a chart.

Public Sub SetSeriesTrendlineColor( index As Integer, color As String )
Public Sub SetSeriesTrendlineColor( index As Integer, color As System.Drawing.Color )

public void SetSeriesTrendlineColor( int index, string color );
public void SetSeriesTrendlineColor( int index, System.Drawing.Color color );

Arguments

index

An integer value that specifies the zero-based index of the series in the chart object.

color

A string that specifies the color or a System.Drawing.Color structure.

Remarks

By default, a trendline takes its colors from the chart style.

This method does not add a trendline to a series. The trendline should have been previously added to the series with Swiff Chart.

If the index argument refers to a series that does not exist in the chart object, the series is created.

• index must be superior or equal to 0

The color string argument can be specified:

• As a named color.
  Example: "orange"
  

  For a complete reference of predefined named colors, consult the Predefined Colors Reference.
  Named colors are always opaque.
  

• As a hexadecimal value "#RRGGBB", where RR, GG and BB represent the hexadecimal values of the red, green and blue components.
  Example: "#FFA500" represents an orange color.
  

  An optional alpha component can be added at the end of the string: "#RRGGBBAA".
  Example: "#FFA50080" represents a semi-transparent orange color, "#FFA500FF" represents an opaque orange color, "#FFA50000" represents an fully transparent (invisible) orange color.
  

When generating several charts using a single chart object, the ClearAll method can be used between each generated charts.

Sample Code

The following code illustrates use of the SetSeriesTrendlineColor method.

Dim values As Double(2)

' Define the series #0
values(0) = 10.5
values(1) = 12.4
values(2) = 15.9
chart.SetSeriesValuesFromArray(0, values)

' Define the series #1
values(0) = 13.1
values(1) = 15.6
values(2) = 19.2
chart.SetSeriesValuesFromArray(1, values)

chart.LoadStyle("C:\\my-style-with-trendline.scs")

' Set the color of trendline associated to series #1
chart.SetSeriesTrendlineColor(1, "tomato")

double[] values= new double[3];

// Define the series #0
values[0] = 10.5;
values[1] = 12.4;
values[2] = 15.9;
chart.SetSeriesValuesFromArray(0, values);

// Define the series #1
values[0] = 13.1;
values[1] = 15.6;
values[2] = 19.2;
chart.SetSeriesValuesFromArray(1, values);

chart.LoadStyle("C:\\my-style-with-trendline.scs");

// Set the color of trendline associated to series #1
chart.SetSeriesTrendlineColor(1, "tomato");
