Hoping someone can assist with using this node. Not sure how Epsilon relates to this function (evenness of distribution?)

Was expecting the node to return values similar to the 3rd column, but am only getting values from ~ 85% onwards.

ID Value Percent Rank
1 2 5%
2 3 10%
3 3 15%
4 13 20%
5 16 25%
6 19 30%
7 23 35%
8 24 40%
9 27 45%
10 28 50%
11 30 55%
12 32 60%
13 34 65%
14 37 70%
15 39 75%
16 50 80%
17 63 85%
18 75 90%
19 99 95%
20 102 100%

Avg = 35.95

Median = 28

How have you configured the Percent Rank node?
Can you provide a sample graph?

The Epsilon value is used for comparison of the values, if the field referenced by the InputExpr is a floating point (double) value.
For more information, you can see the help for each of these parameters if you hover over the parameter name (a tool-tip will popup).
Alternately, you can click on "Node Help" when in the Node editor, and the full help for the node will be displayed in a browser window.

I have tried configuring the node myself, and the output seems to be as expected - i.e. pretty similar to the values in your "Percent Rank" column above (where 5% would be represented as 0.05 etc).

I have attached the graph with this configuration.

Let me know if this helps, or if you have additional questions.

Tim.
