Method Detail

setCoeff

void setCoeff(int coeff)

please see the derived classes for details

getCoeff

int getCoeff()

please see the derived classes for details

setTitle

void setTitle(java.lang.String title)

Sets the title for this data line

Parameters:

title - the title for this line used in the legend. If the title is null or unspecified, the default name is used as described above.

getTitle

java.lang.String getTitle()

Returns the title for this data line

Returns:

the title of the data line

useSecondaryValue

void useSecondaryValue(boolean state)

Set to use secondary value instead of primary value. This is valid only when the chart contains secondary axis (i.e. combo chart). Default is false.

Parameters:

state - set true to use secondary axis data value

isSecondaryValueUsed

boolean isSecondaryValueUsed()

Get the state of using subvalue data

Returns:

true if subvalue is used to plot data line

setValueColumn

void setValueColumn(int hlco_value)

This is used for HLCO and High Low chart only
For this type of chart you can specify which values : HIGH, LOW, CLOSE, OPEN to use. The default is CLOSE, if it is not defined, HIGH is used instead.

Parameters:

hlco_value - one of HIGH, LOW, CLOSE, OPEN

getValueColumn

int getValueColumn()

Get the value uses for fitting for HLCO and High Low chart

Returns:

one of HIGH, LOW, CLOSE, OPEN

setSeries

void setSeries(java.lang.String series)

This is used for charts with data series only. The data line is drawn for this particular series. If the series name is not defined or does not match the series name of data, the data line is not drawn. To get the series name, use the properties SERIES_ORDER.

Parameters:

series - data series name use to plot for this data line.

getSeries

java.lang.String getSeries()

Get the name data serie use of this data line for chart with data series.

Returns:

name of data series

setShowHintValue

void setShowHintValue(boolean bshow)

Set true/false to show the LineValue of data line in hint dialog box

getShowHintValue

boolean getShowHintValue()

Return true if the LineValue of data line show in hint box

getValueHint

java.lang.String getValueHint()

Return the string use in the LineValue hint

setValueHint

void setValueHint(java.lang.String hint)

Set the string use in the LineValue hint

setLineType

void setLineType(int lineType)

please see the derived classes for details

getLineType

int getLineType()

Get the line type

Returns:

line type

setColor

void setColor(java.awt.Color color)

Sets the line color. The default color is black.

Parameters:

color - line color

getColor

java.awt.Color getColor()

Get the color of the data line

Returns:

line color

setLineValue

void setLineValue(double line_value)

please see the derived classes for details

getLineValue

double getLineValue()

please see the derived classes for details

setTitleVisibleInLegend

void setTitleVisibleInLegend(boolean b)

Makes the data line title visible in the legend. The default is true.

Parameters:

b - if true, the title is displayed, hidden otherwise.

isTitleVisibleInLegend

boolean isTitleVisibleInLegend()

Returns whether the data line title being displayed in legend

Returns:

true if title is displayed, false otherwise

getThickness

int getThickness()

Gets the line thickness.

Returns:

line thickness.

setThickness

void setThickness(int thickness)

Sets the line thickness. The default thickness is 1.

Parameters:

thickness - the line thickness.

getLineStyle

int getLineStyle()

Valid for horizontal lines and vertical lines only Get the line style of this line Please see setLineStyles method in quadbase.util.IDataPointSet for the definition of line style

Returns:

lineStyle

See Also:

IDataPointSet

setLineStyle

void setLineStyle(int lineStyle)

Sets the line style. By default, the line style is SOLID_STYLE. Please see setLineStyles method in @see quadbase.util.IDataPointSet for the definition of line style.
IDataLine.SOLID_STYLE, IDataLine.DASH_STYLE and IDataLine.DOTTED_STYLE are pre-defined styles.
SOLID_STYLE = 0;
DASH_STYLE = (20 << 16 | 5 << 8);
DOTTED_STYLE = (5 << 16 | 5 << 8);

Parameters:

lineStyle - line style of this line

 A line style number, z, satisfies the equation:
        z = 256*fill + empty
 where fill is the number of fill pixels (solid part of dashed line)
 and empty is the number of blank pixels (empty part of dashed line)
 with fill < 256 and empty < 256.
 By setting well-defined numbers for z, users can create different
 types of connect lines.
