<div>I don't think there is any built in function in ParaView, but you can convert a histogram to a cumulative distribution by applying the Python Programmable Filter with the following script:</div>

</div>
<div>I noticed that when you apply the filter, ParaView wants to show it in a spreadsheet view. However, it works if you make it visible in the bar chart view created for the histogram. You can also create a line chart view and display it there.</div>

<div>Hope that helps.</div>
