Field Detail

lastTickY

private float lastTickY

Constructor Detail

YAxis

public YAxis(AxisChart axisChart,
             int numberOfScaleItems)

Constructor

Parameters:

axisChart -

Method Detail

getLastTickY

public float getLastTickY()

Need this value as horizontal plots start from the top of the axis and go down

Returns:

computeMinimumWidthNeeded

public void computeMinimumWidthNeeded(String yAxisTitle)

Computes the minimum pixel width required for the Y-Axis. Includes space, if needed, for: axis title + padding, axis values + tick padding, and tick marks.

renderAxisTitle

private void renderAxisTitle(String axisTitle,
                             Graphics2D graphics2D,
                             AxisTypeProperties axisTypeProperties)

Parameters:

axisTitle -

graphics2D -

axisTypeProperties -

render

public void render(Graphics2D graphics2D,
                   AxisProperties axisProperties,
                   String yAxisTitle)

Renders the YAxis on the passes Graphics2D object

Parameters:

graphics2D -

axisProperties -

yAxisTitle -

computeAxisCoordinate

public float computeAxisCoordinate(float origin,
                                   double value,
                                   double axisMinValue)

Takes a value and determines the screen coordinate it should be drawn at. THe only difference between this and the x-axis is we subtract to the origin versus subtract from it.

Parameters:

origin -

value -

axisMinValue - the minimum value on the axis

Returns:

float the screen pixel coordinate

toHTML

public void toHTML(HTMLGenerator htmlGenerator)

Enables the testing routines to display the contents of this Object.

Specified by:

toHTML in interface HTMLTestable

Overrides:

toHTML in class Axis

Parameters:

htmlGenerator -
