Class RMGraphIntervals

java.lang.Object
  com.reportmill.graphing.RMGraphIntervals

public class RMGraphIntervals
extends java.lang.Object

Returns a list of graph intervals given a range and count. If count is zero, this class will determine a proper count.

Constructor Summary

RMGraphIntervals(float minValue, float maxValue, int aCount)
Return well-chosen intervals given a min/max value.

Method Summary

static RMGraphIntervals	getGraphIntervals(RMGraph aGraph) Returns graph intervals for a given graph.
java.lang.Float	getInterval(int anIndex) Returns the individual interval at a given index as a float value.
int	getIntervalCount() Returns the number of intervals for this filled graph.
java.lang.Float	getIntervalLast() Returns the last interval as a float value.

Constructor Detail

RMGraphIntervals

public RMGraphIntervals(float minValue,
                        float maxValue,
                        int aCount)

Return well-chosen intervals given a min/max value. For instance, (1,4) would return (1,2,3,4,5), while (17,242) would return (50,100,150,200,250). Useful methods for graphing.
