Constructor Detail

JRDesignMeterPlot

public JRDesignMeterPlot(JRChartPlot plot,
                 JRChart chart)

Construct a new meter plot by copying an existing one.

Parameters:

plot - the plot to copy

Method Detail

setDataRange

public void setDataRange(JRDataRange dataRange)
                  throws JRException

Sets the range of values that the meter can display. Before changing this for an existing meter you should clear any existing intervals to ensure that you don't end up with intervals that are outside of the new range.

Parameters:

dataRange - the range of values that the meter can display

Throws:

JRException

setValueDisplay

public void setValueDisplay(JRValueDisplay valueDisplay)

Sets the value display formatting options.

Parameters:

valueDisplay - how to show the textual representation of the value

setShape

public void setShape(MeterShapeEnum shape)
              throws JRException

Sets the shape of the meter. Must be one of MeterShapeEnum.CHORD, MeterShapeEnum.CIRCLE, MeterShapeEnum.PIE or MeterShapeEnum.DIAL.

Parameters:

shape - the shape of the meter

Throws:

JRException - invalid shape was specified

addInterval

public void addInterval(JRMeterInterval interval)

Adds an interval to the meter. An interval is used to indicate a section of the meter.

Parameters:

interval - the interval to add to the meter

clearIntervals

public void clearIntervals()

Removes all the intervals for the meter.

setIntervals

public void setIntervals(Collection<JRMeterInterval> intervals)

Sets the meter intervals.

Parameters:

intervals - the list of meter intervals (JRMeterInterval instances)

See Also:

addInterval(JRMeterInterval)

setMeterAngle

public void setMeterAngle(Integer meterAngle)

Sets the size of the meter face in degrees.

Parameters:

meterAngle - the size of the meter in degrees

setUnits

public void setUnits(String units)

Sets the units string to use. This string is appended to the value when it is displayed.

Parameters:

units - the units string to use

setTickInterval

public void setTickInterval(Double tickInterval)

Sets the space between tick marks on the face of the meter. The spacing is relative to the range of the meter. If the meter is displaying the range 100 to 200 and the tick interval is 20, four tick marks will be shown, one each at 120, 140, 160 and 180.

Parameters:

tickInterval - the space between tick marks on the meter

setMeterBackgroundColor

public void setMeterBackgroundColor(Color meterBackgroundColor)

Sets the color to use for the meter face.

Parameters:

meterBackgroundColor - the color to use for the meter face

setNeedleColor

public void setNeedleColor(Color needleColor)

Sets the color to use for the meter pointer.

Parameters:

needleColor - the color to use for the meter pointer

setTickColor

public void setTickColor(Color tickColor)

Sets the color to use when drawing tick marks on the meter.

Parameters:

tickColor - the color to use when drawing tick marks

setTickCount

public void setTickCount(Integer tickCount)

Sets the number of major tick marks on the meter scale.

Parameters:

tickCount - the number of major tick marks

setTickLabelFont

public void setTickLabelFont(JRFont tickLabelFont)

Sets the font to use when displaying the tick label.

Parameters:

tickLabelFont - the font to use when displaying the tick label
