Improvements When Changing Data Source of Data Connector

Show Options dialog checkbox is added in Data Source File Path dialog

In older version, on a sheet with data connector, when clicking the connector icon and choose Data Source… to change data file, after clicking OK, new data wasn’t imported directly. The subsequence Import Options dialog always showed for user to confirm the settings but most of the time user just needed to click OK without any change.

In Origin 2025, Show Options dialog checkbox is added and by default unchecked so data can be imported directly after clicking OK.

Python supports setting parameter bounds in NLFit

Added following function to set parameter bounds in NLFit.

def set_lbound(self, p, ctrl='>', val=None)
def set_ubound(self, p, ctrl='<', val=None)

Example:

import originpro as op
wks = op.new_sheet()
fn=op.path('e') + r'Samples\Curve Fitting\Gaussian.dat'
wks.from_file(fn, False)
model2 = op.NLFit('Gauss')
model2.set_data(wks, 0, 1)
model2.set_lbound('y0','>','6')
model2.set_ubound('A','<','800')
model2.fit()
