Run analysis then duplicate it for data in the other sheets.

Click the analysis lock on result to choose Duplicate Operation for Specified Sheets menu.

Note: not supported for analysis with matrix/virtual matrix/image.

In Origin2025b, only show long name of fit curve in fitted plot legend, if perform fitting on graph mulitple times and find the best model, it’s hard to figure out the function of the fitted curve, now show fitted curve legend to function name, e.g. Gauss Fit

Supports a new interactive tool, allow to creat plot with categorical data as group variable simply by drag and drop

1. Scatter (Line, Line+Symbol)

2. Histogram (Distribution Cuve, Probability Plot, QQ-Plot, CDF Plot)

3. Box (Interval, Bar, Violin)

4. Column (Bar, Pie, Doughnut)

Support Equal Variance Test for Two-Way ANOVA

Choose Statistics ? Regression ? Logistic Regression main menu to open app then click the Binary Logistic button.

Go to the Fits and Diagnostics tab and check the Predicted Value options. Click OK and it will generate FindYfromX sheet to predict.

Power and Sample Size: t test (1-sample, 2-sample, paired-sample):

• Tail ? Alternative Hypothesis

• 2 side ? Not Equal

• 1 side ? Greater than

• add one more option: Less than.

Support Interpolate/Extrapolate on Snapped X for All Plots checkbox to exclude the non-existent data in Gadgets: Vertical Cursor.

For different X range data in one graph layer, when Gadgets: Vertical Cursor it will Extrapolates non-existent data by default, can exlude the non-existent data by clear checkbox Interpolate/Extrapolate on Snapped X for All Plots
