Method Detail

dataRange

public void dataRange(double[] range)

Update the data range, range = {xmin,xmax,ymin,ymax}. The entries in range are updated to reflect the extent of the data in this node. The argument range is an input/output variable. Its value should be updated only if the data in this node is outside the range already in the array.

Overrides:

dataRange in class Data

Parameters:

range - a double array which contains the updated range, {xmin,xmax,ymin,ymax}

getClose

public double[] getClose()

Gets the value of the attribute "Close". return a double array of closing stock prices.

getHigh

public double[] getHigh()

Convenience routine to get the "High" attribute.

Returns:

the double array of high stock prices.

getLow

public double[] getLow()

Convenience routine to get the "Low" attribute.

Returns:

the double array of low stock prices.

getOpen

public double[] getOpen()

Gets the value of the attribute "Open". return a double array of opening stock prices.

paint

public void paint(Draw draw)

Paints this node and all of its children. This is normally called only by the paint method in this node's parent.

Overrides:

paint in class Data

Parameters:

draw - the Draw object to be painted

setClose

public void setClose(double[] value)

Sets the attribute "Close".

Parameters:

value - a double array of closing stock prices.

setDateAxis

public void setDateAxis(String labelFormat)

Sets up the x-axis for high-low-close plot. This turns off autoscaling on the x-axis and sets the Window attribute depending on the number of dates being plotted. The Number attribute determines the number of intervals along the x-axis.

Parameters:

labelFormat - is used to format the date axis labels. It sets the TextFormat attribute in the AxisLabel node.

See Also:

AbstractChartNode.setTextFormat(String), AxisLabel

setHigh

public void setHigh(double[] value)

Convenience routine to set the "High" attribute.

Parameters:

value - an double array of high stock prices.

setLow

public void setLow(double[] value)

Convenience routine to set the "Low" attribute.

Parameters:

value - an double array of low stock prices.

setOpen

public void setOpen(double[] value)

Sets the attribute "Open".

Parameters:

value - a double array of opening stock prices.
