Hello
I have a confusing problem when writing a plugin. When I put numbers into the results table and plot as well, the list in plot dialog shows numbers with different precision than the results.
I have  in this example set decimal places to 9 and enabled Scientific Notation.
Here is what I get:
Results table 2. Column and List from Plot 3.rd column
1    1.695265623E0 1.695265651E0
2    1.741630384E0 1.741630435E0
3    1.996989389E0 1.996989369E0
4    1.756611630E0  1.756611586E0
5    1.594811512E0  1.594811559E0
6    1.329282159E0 1.329282165E0
7    1.114680459E0 1.114680409E0
8    9.434604256E-1 9.434604049E-1
9    9.000309046E-1 9.000309110E-1
10    7.652984144E-1  7.652984262E-1

Do anyone have any explanation? The correct values should be the 2. Column as I have checked by direct print.
I have no statements to set the precision an let ImageJ default rule.

Best regards
Knut Kvaal
