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=67852#comment-67852 ] Andreas Guelzow commented on OFFICE-3936: ----------------------------------------- My Suggestion for 20.27: 20.27 The chart:interval-major attribute specifies major intervals on an axis 11.8. If the axis is linear and the value of this attribute is x, major ticks are placed at n*x for n being any (positive, negative or zero) integer. If the axis is logarithmic and the value of this attribute is x, major ticks are placed at 10^(n*x) for n being any (positive, negative or zero) integer. (Note: if x = log(y), then 10^(n*x) = y^n.) > 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)
