Subject: [OASIS Issue Tracker] (OFFICE-3936) logarithmic scale misses information about basis
[ https://issues.oasis-open.org/browse/OFFICE-3936?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=67861#comment-67861 ] Regina Henschel commented on OFFICE-3936: ----------------------------------------- The major grid is different too. With chart:minimum="2" chart:maximum="2048" chart:interval-major="0.602059991327962" [= log10(4)] chart:interval-minor-divisor="4" LibreOffice has major grid at 2, 8, 32, 128, 512, 2048. That means, that LibreOffice always starts with grid at minimum. So LibreOffice places the major ticks at minimum*10^(n*x) and does not use negative n. Example file is https://beta.opendocumentformat.org/upload/de/263. > logarithmic scale misses information about basis > ------------------------------------------------ > > Key: OFFICE-3936 > URL: https://issues.oasis-open.org/browse/OFFICE-3936 > Project: OASIS Open Document Format for Office Applications (OpenDocument) TC > Issue Type: Improvement > Components: Chart > Affects Versions: ODF 1.2 > Reporter: Regina Henschel > Fix For: ODF 1.3 > > > http://docs.oasis-open.org/office/v1.2/os/OpenDocument-v1.2-os-part1.html#property-chart_interval-major > Although the basis 10 is widely used, others a common too, e.g basis 2 for audiogram. > This proposal adds not only the basis but additional details to the description of chart:interval-major and chart:interval-minor-division. > Specifications are not only read by developers but by authors of guides and tutorials too. For those the mathematic impact of the attributes values might be not obvious. > Formulas in the proposal are written StarMath. > I think, that logarithmic scale should only be allowed for a value-axis, but have not included that in this proposal. -- This message was sent by Atlassian JIRA (v6.2.2#6258)
