"Extract Pulse Feature" display rounded value in legend

[ThomasMalletCodra]

Describe the bug
Inconsistent legend values

When running "Extract pulse feature" , the values displayed in the result legend are not consistent with the actual measured values on the curve. This appears to be a display formatting issue (Significant figure/Scientific writing).

To Reproduce
Steps to reproduce the behavior:

1. Open DataLab
2. Import the attached CSV signal file (extract_pulse_issue.csv)
3. Run Computing → Extract pulse feature on the imported signal
4. Observe that:
   • The legend values do not match the values visually measured on the plot

Expected behavior

• The legend should display values consistent with the curve data table
