It does look like the scale in the pareto plot platform is locked to linear, as it is in distribution like you mentioned. If you're interested in the plot itself (rather than the additional functionality of the Pareto plot platform), and you're willing to give up the cumulative percentage line, you could use graph builder with the following steps:
- Drag Class to X
- Drag N Rows to Y
- Select Bar Chart
- To order bars by count, drag "N Rows" on top of "class" on x-axis
- To select descending order, right click X-axis label on top of "(ascending)" and then uncheck Ascending
- Double click Y axis and set scale to Log
Below is also a video with these steps. I hope this helps at least a little bit!
