Chart from dynamic array challenge
Hi (Excel 365 v2512 b19530.20144 Current Channel / Windows 11 25H2) Charts are definitively not my thing. Spent hours on the following, searching, testing… to no available The below chart data range is a dynamic array (could be wrong for the desired chart) - named GRAPH_Series on sheet GRAPH_Ranges - similar to the array on the left side of the pic. The arrays dynamically resize according to the 'START Year' & 'TOPN Cat' variables - so far so good Setting the Chart data range as =GRAPH_Ranges!GRAPH_Series and changing nothing else the chart updates as expected according to the 'START Year' & 'TOPN Cat'. On the other hand if I change anything in the Select Data Source dialog box the chart won't update properly anymore The expected chart is the same as above with 2020, 2021...2025 (instead of 1, 2,...6) horizontally & D, F, B, A as legend (instead of Series1, Series2...Series4) Thanks & any question please let me know Lz.
Excel pads dynamic array output with #NV values
I have come across a couple of instances, where Excel 365 pads the output (of lambdas) or in this case of a specific formula within a lambda with #NV values (or errors if you like to treat them so.) The following snippet: = LAMBDA(assemblyName; LET( filteredParams; {"a";"b";"c"}; mappedValues; {1;2;3}; transposed; MTRANS(HSTAPELN(filteredParams; mappedValues)); return; WENN(filteredParams = ""; "NV"; transposed); return ))("fake") Gives me the following output: a b c 1 2 3 #NV #NV #NV At the same time, the following slightly different code (letting alone the output of WENN): = LAMBDA(assemblyName; LET( filteredParams; {"a";"b";"c"}; mappedValues; {1;2;3}; transposed; MTRANS(HSTAPELN(filteredParams; mappedValues)); return; WENN(filteredParams = ""; "NV"; transposed); transposed ))("fake") Spits out: a b c 1 2 3 This is not the only case, but is the simpliest, I can reconstruct this kind of error with. Do not mind the logic, it is an edited excerpt, just for illustration. P. S. It is German syntax. English would have TRANSPOSE, HSTACK, IF,... instead. Maybe a little difference in punctuation.

Hi everyone, I recently wrote a blog post on some simple, yet powerful, techniques for anyone who works with Excel spreadsheets, especially those with complex data. I wanted to share a summary of it with this community, as it might be helpful to others who are looking to understand and protect their work. The post covers two main things: Quickly Revealing All Formulas: A simple keyboard shortcut (Ctrl + `) or the "Show Formulas" option can instantly reveal all formulas in a worksheet. This is a great way to quickly see how a spreadsheet is structured. Permanently Highlighting Formulas: The article shows how to use the "Find & Select" > "Formulas" feature to select all cells containing formulas and then permanently highlight them with a fill color. This visual cue can help prevent accidental edits and protect your data.

Charting help needed
Dear Experts, I have a data as below, So , in Column "G" we have 2 Rntis( 21,8,66 & 53714), and I need to plot the time difference for report of each rnti, which is calculated by subtracting the consecutive - SFNs, for that rnti. Now , the problem here is that in below for example , for the rnti-53714, it's not correct, for example at row-244, my last report for rnti=53714 came at row 241, so the difference should be (821-789) * 10, while in my case it's doing the subtraction in consecutive SFNs, which basically messes up my analysis. I tried to do something like below from column W to AF, but not sure how to achieve this properly( X axis should be my time, Y axis should be my average-ms and distribution should be based on the RNTI. Attached is the worksheet..(anything in -ve and above 400 is Outliers and need to be removed) in ms column also. Thanks in Advance! Br, Anupam
