Class ZoomBothAxis
java.lang.Object
de.laures.cewolf.cpp.ZoomBothAxis
- All Implemented Interfaces:
- ChartPostProcessor, java.io.Serializable
public class ZoomBothAxis
- extends java.lang.Object
- implements ChartPostProcessor, java.io.Serializable
A postprocessor for altering the domain and range of a chart, essentially creating a way to "zoom into" a chart.
The zooming cabilities for the range (y) axis works for all plots.
The capabilities for the domain (x) axis work only for x/y and timeseries plots (currently only has capabilities to define hours) only, not category plots.
(Note: in order for the set range capabilities to work properly, it is recommended that the "rangeIncludesZero" be set to false using a VisualEnhancer postprocessor.)
The following parameters can be used:
lowerRangeVal optional, default value produced by chart; the lowest value that will be graphed on the range (y) axis
upperRangeVal optional; default value produced by chart; the highest value that will be graphed on the range (y) axis
lowerDomainValN optional; default value produced by chart; the lowest value that will be graphed on the domain (x) axis for a numerical plot (xy plot)
upperDomainValN optional; default value produced by chart; the highest value that will be graphed on the domain (x) axis for a numerical plot (xy plot)
lowerDomainValD optional; default value produced by chart; the minimum time that will be graphed on the domain (x) axis for a time scale graph (timeseries plot)
upperDomainValD optional; default value produced by chart; the maximum time that will be graphed on the domain (x) axis for a time scale graph (timeseries plot)
zoomFactor optional; default 1.0; value to zoom in on the center point
anchorValueD optional; no default value; the domain axis (X axis) of xyplots is centered around this value
anchorValueR optional; no default value; the range axis (Y axis) of xyplots is centered around this value
Example usage:
<chart:chartpostprocessor id="zoom">
<chart:param name="lowerRangeVal" value="-3.2" />
<chart:param name="upperRangeVal" value="3.2" />
<chart:param name="lowerDomainValN" value="-6.0" />
<chart:param name="upperDomainValN" value="12.5" />
<chart:param name="lowerDomainValD" value="8:00" />
<chart:param name="upperDomainValD" value="15:00" />
<chart:param name="zoomFactor" value="1.5" />
</chart:chartpostprocessor>

- Description copied from interface:
ChartPostProcessor
- Processes a generated chart. This method is called by the ChartProducer
after a chart instance is generated and before it is rendered (if so).
The ChartProducer is responsible for post processing a chart dependant
on and only on the provided parameters. This means that the same parameters
should result in the same postprocessings.
- Specified by:
processChart
in interface ChartPostProcessor
- Parameters:
chart
- the chart instanceparams
- parameters passed to the postprocessor. These are defined in the JSP- See Also:
