'0' should not Refer to Last Index if By X

1. Open the integ1 XF then expand Input: Range1: Rows node, set Rows by X.

2. Set To’s value as 0 and click OK.

==> 0 in here will refer to last row and it will generate wrong result.

Issue existed since Origin 2021b and fixed in Origin 2025.

PA does not report baseline fit parameters

When perform a baseline finding or baseline subtraction using a fitting function (such as poly5).

==>The fit parameters of the baseline are not stored anywhere for user to access.

Fixed in Origin 2025.

1. When goal of PA is Create Baseline or Subtract Baseline, if baseline is fitted curve, will add function name and function parameter to comments of Y.

2. When goal of PA is other option, will add function name and function parameter to Baseline_Data result sheet.

ORG-29418

Correlation Coefficient Spearman shows wrong results when Kendall unchecked

1. This issue happened if input data has too may duplicate values, e.g. one value repeated more than 1024 times in one column.

2. Open Correlation Coefficient dialog. Check Spearman checkbox, keep Kendall uncheck. Click OK.

==>Spearman table shows wrong results.

Fixed in Origin 2025.

ORG-29416

Improve speed of range interpolation

Origin 2025 improved issues as below:

1. Improve speed of range interpolation for large dataset

2. Fixed the issue about Range interpolation wrongly calculating -NAN(IND)

3. Fixed the issue about X-Function Interp1 Output Result to Hidden Row

ORG-28116

Improve two-sample t-test for special case

Origin 2025 improved One-Sample T-Test, Two-Sample T-Test, Pair-Sample T-Test.

When at least one of column’s SD is zero, Origin will show the footnote text in “t-Test Statistics” table like below.

ORG-29816

Wrong X result data if smooth on different partial ranges

Bug since multiple input are supported in smoothing tool in Origin 2024.

To see the issue:

1. Highlight two Y column to smooth.

2. In Input node, expand Range1 and Range2 subnodes and set different rows to smooth.

3. Set output to new workbook.

4. ==> Same X column is used in output which is wrong. Each smoothed data should have its own X column.

ORG-29886

No lock in graph if plot from image matrix with lock

Plot graph from the image matrix window with analysis lock.

==> No analysis lock in the plotted graph.

Note: this issue existed since Origin 2021 and fixed in Origin 2025.
