Constructor Detail

ErrorBar

public ErrorBar(AxisXY axis,
                double[] x,
                double[] y,
                double[] low,
                double[] high)

Creates a set of error bars centered at (x[k],y[k]) and with extents low[k],high[k]. If the attribute "DataType" has the bit DATA_TYPE_ERROR_X set then this is a horizontal error bar. If the bit DATA_TYPE_ERROR_Y is set then this is a vertical error bar. If neither bit is set then no error bar is drawn.

A Data node with the same x and y values can be used to put markers at the center of each error bar.

Parameters:

axis - an Axis object

x - a double array which contains the x coordinates of the points at which the error bars will be centered. This is used to set the "X" attribute.

y - a double array which contains the y coordinates of the points at which the error bars will be centered. This is used to set the "Y" attribute.

low - a double array which contains the values which define the minimum extent of the error bars. This is used to set the "Low" attribute.

high - a double array which contains the values which define the maximum extent of the error bars. This is used to set the "High" attribute.

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}

getHigh

public double[] getHigh()

Convenience routine to get the "High" attribute.

Returns:

the double array which contains the value of the "High" attribute

getLow

public double[] getLow()

Convenience routine to get the "Low" attribute.

Returns:

the double array which contains the value of the "Low" attribute

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

setHigh

public void setHigh(double[] value)

Convenience routine to set the "High" attribute.

Parameters:

value - an double array which contains the "High" values.

setLow

public void setLow(double[] value)

Convenience routine to set the "Low" attribute.

Parameters:

value - an double array which contains the "Low" values.
