/**
 * Adjusts the Y-axis so that abnormally large value won't spoil the whole chart
 * by making everything look virtually 0.
 *
 * <p>/* w  w  w .j a  v  a 2 s.c  o  m*/
 * The algorithm is based on <a href="http://en.wikipedia.org/wiki/Chebyshev%27s_inequality">Chebyshev's inequality</a>,
 * which states that given any number sequence, nore more than 1/(N^2) values are more than N x stddev away
 * from the average.
 *
 * <p>
 * So the algorithm is to set Y-axis range so that we can see all data points that are within N x stddev
 * of the average. Most of the time, Cebyshev's inequality is very conservative, so it shouldn't do
 * much harm.
 *
 * <p>
 * When the algorithm does kick in, however, we can kick out at most 1 in N^2 data points.
 * (So for example if N=3 then we can "fix" the graph as long as we only have less than 1/(3*3)=11.111...% bad data.
 *
 * <p>
 * Also see issue #1246.
