We should be able to create histograms of a column of data just by selecting that column and creating a chart. The bin number and log/linear spacing of bins, etc can be set in the plot options window. Currently it's possible to make histograms using the FREQUENCY() command, but it requires extra plot-only things being added to the spreadsheet.
Please, could you elaborate a bit? I use histogram charts and I never used FREQUENCY() command. Set status to NEEDINFO. Please set it back to UNCONFIRMED once you have provided requested informations. Thank you for your understanding. Best regards. JBF
Can you please describe how to do it without FREQUENCY() command? For example, if data is 1 2 3 11 12 13 45 and the bins are 0-10, 11-20, 21-30, etc, then the histogram would have a height of 0-10: 3 11-20: 3 21-30: 0 31-40: 0 41-50: 1 51-60: 0 https://en.wikipedia.org/wiki/Histogram http://ask.libreoffice.org/en/question/17/how-do-you-plot-a-histogram-in-libreoffice-calc/?answer=10011#post-id-10011 http://ask.libreoffice.org/en/question/19816/ https://bugs.freedesktop.org/show_bug.cgi?id=81530
Ok, with complete information it is easier to understand what you mean. For many users who are not statisticians histogram could be understand as bar chart. Valid enhancement request. Best regards. JBF

For comparison, Google Sheets allows you to highlight a single column of data, click Insert -> Chart, and it creates a Histogram immediately, by default. You can then change the "bucket size" in the chart options, etc. (It doesn't allow you to specify differently-sized "buckets" though, as desired in bug 81530.)
Please also see bug 74665's attachment 192673 [details] for inspiration from Gnumeric's dialog. Devansh is currently working on this as part of GSoC, see work in progress on gerrit: https://gerrit.libreoffice.org/c/core/+/167068 Devansh, you can mark this report as "assigned" and add yourself to the "Assignee" field.

Created attachment 195283 [details] Patch 42 of Histogram Chart This is what we are able to have for the histogram chart, as can be seen in the screenshot. The bars seem to be much wider, which will be updated in an upcoming patch if needed. As of now, we are using the sqrt method to calculate the number of Bins - void HistogramChartType::computeBinFrequencyHistogram(const std::vector<double>& dataPoints) { //...code m_nBins = static_cast<sal_Int32>(std::sqrt(dataPoints.size())); //...code }
varshneydevansh committed a patch related to this issue. It has been pushed to "master": https://git.libreoffice.org/core/commit/07ae0e5ada7cb595eb4815413a5bdd442c32a6ab tdf#82716 Add initial implementation of the Histogram Chart It will be available in 25.2.0. The patch should be included in the daily builds available at https://dev-builds.libreoffice.org/daily/ in the next 24-48 hours. More information about daily builds can be found at: https://wiki.documentfoundation.org/Testing_Daily_Builds Affected users are encouraged to test the fix and report feedback.
I have opened the meta bug 162134 to track follow-up enhancements and bugs. Maybe this can be closed as "fixed" then, if you agree, Devansh and Quikee? Thanks for the initial implementation!

Please add to the release notes.

(In reply to Buovjaga from comment #19) > (In reply to Mike Kaganski from comment #18) > > Please add to the release notes. > > Renewing the request: https://wiki.documentfoundation.org/ReleaseNotes/25.2 I think, it should not be added to the ReleaseNotes for 25.2. The feature is in a state that it should not be published with 25.2. The main problem is, that the chosen design does not allow a simple, proper save/load with ODF and use of the chart wizard, and that the chart type itself belongs to an extension of OOXML, for which no code yet exists in LibreOffice. Thus there is currently no way to save/load a Histogram chart. That effects the clipboard as well. The time till rc1 of 25.2 is too short to proper fix the problems. The Histogram chart could be hidden from the UI, only enabled as experimental feature or be removed from the 25.2 release totally. I would prefer the latter, because that keeps is visible as having to be fixed for 25.8.

These two sentences seem to contradict. Can we, or can we not, save histogram charts to ODS, and load them from ODS? > and that the chart type > itself belongs to an extension of OOXML, for which no code yet exists in > LibreOffice. Well, the code exists if it's being considered for 25.2 ... can you clarify what you mean? Note that I'm not against your position; if the feature is indeed not well-baked enough that it should probably wait.

The code does not exist. We cannot save and load from xlsx.
