  + <p>The plot on the left displays the average time per iteration for this benchmark. The shaded region shows the estimated PDF of the measurements, while each point represents one sample. Yellow points are mild outliers, while red points are severe outliers. Click on the plot for a larger view.</p>
  + <p>The plot on the right shows the linear regression calculated from the measurements. Each point represents a sample, though here it shows the total time for the sample rather than time per iteration. The line is the line of best fit for these measurements.</p>

  + <p>The plot on the left shows the probability of the function taking a certain amount of time. The red curve represents the saved measurements from the last time this benchmark was run, while the blue curve shows the measurements from this run. Click on the plot for a larger view.</p>
  + <p>The plot on the right shows the two regressions. Again, the red line represents the previous measurement while the blue line shows the current measurement.</p>
