<p>A histogram of the sample cumulative distribution is computed dynamically without storing samples based on the <span class="inlinemediaobject"><img src="../../../images/accumulators/form_11.png"></span> algorithm. The returned histogram has a specifiable amount (num_cells) equiprobable (and not equal-sized) cells.</p>
