jagged cumulative percent in Pareto chart

[Anonymous]

The cumulative percent line on my My Power BI Pareto chart presents as a jagged line. An Excel chart using the same data shows a smooth line. Is this unique to Power BI? The problem appears to be the way Power BI handles adjacent causes having the same counts. Anyone else seen this? Is there a fix? Thank you.

This is what I see in Power BI.

This is what I see in Excel.

Problem solved.
The Pareto chart was sorting by count in descending order.
The correction was to sort by cumulative percent in ascending order.
