Origin 2025b Bug Fixes

ORG-30289

Improve Merge Graph Windows exclude rule

Multi-layer graphs (e.g. multi-panel graph made by previous merging) were excluded in Merge Graph Windows Dialog.

The rule is improved in 2025b so that

• If the multi-layer graph is within same rectangle frame, it will be included.

• If all graphs are multi-layer graphs, so the number of graphs to include is 0, then all graphs will be included.

If the graph you want to merge is still not included in the dialog, please click > button in Graphs list box to manually add.

ORG-30686

Worksheet row size auto reduces if source data used in calculation is reduced

In older versions, after deleting input data still leaves a lot of empty rows in output column and will accumulate file size.

To see the issue:

1. In worksheet, fill column A with 1 million numbers (rows), e.g. run col(1)=data(1,1E6) in Script window.

2. → The workbook size will be 10MB.

3. Set Column B formula as A+1. The workbook size becomes 19MB.

4. Select row 10 to end in column A and press Delete

5. ==> Data are deleted in both column A and B but the empty rows still exists so workbook size is still 19MB.

Same issue if column is used in other worksheets. If saving project, the file size will be big and recalculation will be slow.

Fixed in Origin 2025b.
