Average Multiple Curves with Different X Ranges Issue  

No extrapolation added when averaging multiple curves

Find solutions that minimize or maximize a function defined in a worksheet's cell.  

Optimization Solver app can be used to find solutions that minimize or maximize a function defined in a worksheet's cell. It can also be used for curve fitting by defining the residual sum of squares as the target function for minimization.

GCAS function has no abs  

abs in the GCAS function is not necessary and so it’s removed now.

HTML Report Assistant  

HTML Report Assistant app

Improvement on Operation Lock tooltip  

Improved info. shows when mousing over the green lock

Moving Average Functions NANUM (Missing value) Ignore or Zero Issues  

Moving Average Functions NANUM (Missing value) Ignore or Zero Issues

Need consistent way for date time data in grouping variable  

Improved tools that support group column with date time data so the output will be sorted by meaningful week, month, quarter, etc. order.

Peak Analyzer default theme setting changes  

Enable Linear Constraints Status and Constraints are checked by default

Perform detrended correspondence analysis.  

Detrended Correspondence Analysis App can be used to perform detrended correspondence analysis (DCA). It is a multivariate method that corrects for the major problems (the arch effect and compression of the ends of the gradient) of Correspondence Analysis.

Perform neural network fitting using Python.  

Neural Network Regression App fits data with neural network backpropagation.

Periodic Report app is capable of grouping data according to periodic date/time range using specified statistical value.  
  • Download Periodic Report app from the page and install the app.

  • With a worksheet window activated, click the app icon to bring up the dialog.

    1. Choose Input columns for grouping, and date/time column for periodic calculation.

    2. Select how to merge the input columns, including 1st point, last point, mean, sd, mean and sd

Pre-ship Fitting Function Library App and show it in appropriate tools  

In Fitting Function Builder and NLFit dialog, there is Fitting Function Library link to download extra fitting functions provided by our website.

Range String Builder dialog updates  

Makes it easier to build output range

Rank multiple fitting functions by their fit reports.  

Rank Models by Fit Reports app can be used to rank fitting functions by fit reports. It can find the optimal model by AIC, BIC, Adj. R-Square, Reduced Chi-Sqr or Residual Sum of Squares.

Set Sampling Interval in average multiple curves result  

If all input Y has same sampling interval, no seperate X column will be created

Significance Label for ANOVA Result Worksheet  

ANOVA Result Worksheet adds Grouping Letters Table in Means Comparison

Statistics on Rows support multiple sheets as input  

In Data Range box, user can enter (1:10)!A:B to do rowwise statistics of column A to B on sheets 1 to 10.

Support Open Book(s) buttons from Summary Sheet when Data Source is set to Use Existing Data  

Buttons on summary sheet will also work if the Data source is Use Existing Data in batch processing

Support set sampling interval on locked columns  

Support set sampling interval on locked columns

Use the apparent values for integration according to the current axis scales.  

Apparent Integration App calculates apparent integral in Cartesian and polar coordinates according to the current axis scales.

Vertical Cursor supports side by side layers  

In the past, Vertical cursor only worked for layers stacked vertically in same graph. Now it will work for layers even on the left or right side

Analysis

Do not modify output designation if column exists  

Output designation not modified if column exists. Meaning: After recalculation, column designations should not be changed.

Fitting result table is wrong if using the theme  

Fitting result table is wrong if using the theme for fitting.

No lock in source graph if using Dynamic input range  

No lock on source graph if using Dynamic input range and output to inputX newY.

Some bug fixes in Non-parametric text

Origin crashes when export ascii with script during batch processing  

Origin crashed when exporting ASCII via script during batch processing.

rowstats Issue with Filtered Data  

Output column pads top with missing values for those filtered out data

Some statistics tools failed on discontinuous ranges  

Some statistics tools failed if selecting discontinous ranges before open the dialog

Speed up Statistics on rows when do batch processing with large data  

Improved the speed of getting data for statistics on rows when doing batch processing with large source data.
