Bug ID: 386800
Summary: Custom fitting often fails
Product: LabPlot2
Version: latest
Platform: MS Windows
OS: MS Windows
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: general
Assignee: alexander.se...@web.de
Reporter: uwesto...@web.de
Target Milestone: ---
Created attachment 108818
--> https://bugs.kde.org/attachment.cgi?id=108818&action=edit
fit parameter b is red
- create a new table with 2 columns
- fill the table columns with row numbers
- create a new custom fit
- use as fit function this one
exp(b*sin(a*x))+c
- set fit interval x:10 - 25
- set as start value for all parameters "1"
result:
1. the fit parameter b gets red, see attached
2. one cannot see the fit functions using the given parameters. Therefore one
doesn't know is the parameter "1" is sensible.
- Now press the recalculate button
result: one doesn't get a fit curve nor sensible values for the fit parameters,
see attached.
But this fit is possible without problems, see the attached screenshot from
MagicPlot.
