Interface IHorzVertLine

All Superinterfaces:

java.lang.Cloneable, IDataLine, IReferenceObj

All Known Subinterfaces:

IControlLine

public interface IHorzVertLine

extends IDataLine

This class is used to draw horizontal/vertical lines in a chart. You may call newHorzVertLine(...) of IDataLineSet interface to get a new object. For instance,
QbChart chart = new QbChart(...);
IHorzVertLine line = chart.gethDataLineSet().newHorzVertLine(...);

Field Detail

HORIZONTAL_LINE

public static final int HORIZONTAL_LINE

VERTICAL_LINE

public static final int VERTICAL_LINE

CIRCULAR_STYLE

public static final int CIRCULAR_STYLE

SEGMENTED_STYLE

public static final int SEGMENTED_STYLE

Method Detail

setLineType

public void setLineType(int lineType)

Sets the line type. The default type is HORIZONTAL_LINE.

Specified by:

setLineType in interface IDataLine

Parameters:

lineType - the type of this data line.

getLineType

public int getLineType()

Get the line type

Specified by:

getLineType in interface IDataLine

Returns:

line type

setLineValue

public void setLineValue(double line_value)

Set the value for the horizontal line or vertical line. For horizontal line if the Y-axis is of numeric value then the line is drawn using line_value, otherwise (i.e. Y-axis contains category name as in bar chart) the value is interpreted as :
1 - draw a line between 1st and 2nd category,
2 - draw a line between 2nd and 3rd category,
etc...
Similarly, line_value = 1.5 will draw a line on the 2nd category.

For vertical line if the X-axis is of numeric value then the line is drawn using line_value, otherwise the value is interpreted as above.

Specified by:

setLineValue in interface IDataLine

getLineValue

public double getLineValue()

Get the line value used by horizontal/vertical line type

Specified by:

getLineValue in interface IDataLine

Returns:

line value

setColorAboveLine

public void setColorAboveLine(java.awt.Color color)

Set the color of all chart data line segments that are above this line value (threshold value) to the desired color. Note that setColorAboveLine has a higher precedence than setColorBelowLine. The method has no effect if data connection lines are not shown. If the chart is not a line chart, the program should call gethDataPoints().setConnectLinesVisible(true) before setting the color. The default value is null. For 2D charts only.

Parameters:

color - the desired color

getColorAboveLine

public java.awt.Color getColorAboveLine()

Return the value of setColorAboveLine(Color). The default value is null. For 2D charts only.

Returns:

The color

setColorBelowLine

public void setColorBelowLine(java.awt.Color color)

Set the color of all chart data line segments which are below this line value (threshold value) to the desired color. Note that setColorAboveLine has a higher precedence than setColorBelowLine. The method has no effect if data connection lines are not shown. If the chart is not a line chart, the program should call gethDataPoints().setConnectLinesVisible(true) before setting the color. The default value is null. For 2D charts only.

Parameters:

color - the desired color

getColorBelowLine

public java.awt.Color getColorBelowLine()

Return the value of setColorBelowLine(Color). The default value is null. For 2D charts only.

Returns:

The color
