Constructor Detail
XAxis
public XAxis(AxisChart axisChart, int numberOfScaleItems)(Code)

Parameters:
  axisChart -
Parameters:
  numberOfScaleItems -




Method Detail
computeAxisCoordinate
public float computeAxisCoordinate(float origin, double value, double axisMinValue)(Code)
Takes a value and determines the screen coordinate it should be drawn at. THe only difference between this and the y-axis is we add to the origin versus subtract from it.
Parameters:
  origin -
Parameters:
  value -
Parameters:
  axisMinValue - the minimum value on the axis float the screen pixel coordinate



computeLabelFilter
public void computeLabelFilter()(Code)
Method to compute the filter to use on the x-axis label display so labels do not overlap



computeMinimumHeightNeeded
public void computeMinimumHeightNeeded(String axisTitle)(Code)
Computes the minimum pixel height required for the X-Axis. Includes space, if needed, for: axis title + padding, axis values + tick padding, and tick marks.
Parameters:
  axisTitle -



computeScalePixelWidth
public void computeScalePixelWidth(AxisTypeProperties axisTypeProperties)(Code)
Computes the number of pixels between each value on the axis.
Parameters:
  axisTypeProperties -



computeShouldTickStartAtYAxis
public void computeShouldTickStartAtYAxis(IAxisDataSeries iAxisDataSeries, AxisTypeProperties axisTypeProperties)(Code)
Determines if we should start x-axis ticks at the y-axis or space it out a half a scale item width.
Parameters:
  iAxisDataSeries -
Parameters:
  axisTypeProperties -



computeTickStart
public void computeTickStart()(Code)
Computes the screen pixel location of the first tick mark



render
public void render(Graphics2D graphics2D, AxisProperties axisProperties, String axisTitle)(Code)
Renders the YAxis on the passes Graphics2D object
Parameters:
  graphics2D -
Parameters:
  axisProperties -
Parameters:
  axisTitle -



toHTML
public void toHTML(HTMLGenerator htmlGenerator)(Code)
Enables the testing routines to display the contents of this Object.
Parameters:
  htmlGenerator -
