/**
 * Quantile Distribution Chart.<br>
 * This chart displays the percentage of requests whose response time is less
 * than some thresholds. The number of thresholds is set by a ChartConfiguration
 * object. Thresholds range from zero to the maximum response time.
 * For example, such a chart makes it possible to visualize that 90% of response
 * times are less than some computed value.
