sim.util.gui.MiniHistogram
public class MiniHistogram
A very simple histogram class. Displays values as different colors left to right. Tooltips pop up describing the actual buckets and their densities.
This class can be used to describe any one-dimensional array of doubles: just provide an array of doubles to setBuckets and it'll show them on-screen. If you change the doubles in that array, no need to call setBuckets again: as soon as a repaint occurs, MiniHistogram will update them. You can also provide a set of bucket labels, one for each bucket, which get popped up in the tooltip along with the current bucket value.
As the class was created to describe histograms in particular, it has two functions
(makeBuckets and makeBucketLabels) which do just that.
Sample usage. The following values are placed into a histogram of four buckets.
MiniHistogram m = new MiniHistogram();
double[] d = new double[] {1, 1, 1, 1, 2, 2, 5, 1, 2, 3, 1, 2, 1, 1, 5, 4};
m.setBuckets(m.makeBuckets(d, 4, 1, 5, false));
m.setBucketLabels(m.makeBucketLabels(4, 1, 5));
