Subject: [OASIS Issue Tracker] Commented: (OFFICE-3731) Public Comment: polynomial regression curve in charts
[ http://tools.oasis-open.org/issues/browse/OFFICE-3731?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=30688#action_30688 ] Andreas Guelzow commented on OFFICE-3731: ------------------------------------------ Gnumeric is currently saving polynomial regression info into ODF files using foreign elements, eg.: <style:chart-properties chart:regression-type="gnm:polynomial" gnm:regression-polynomial-dims="2" gnm:regression-affine="true" chart:lines="true"/> Note that specifying a minimum degree as suggested in the proposal attached to the message would destroy any chance of a unique regression curve. (For example for data that lies on a straight line there is no unique best fit truly quadratic regression.) > Public Comment: polynomial regression curve in charts > ----------------------------------------------------- > > Key: OFFICE-3731 > URL: http://tools.oasis-open.org/issues/browse/OFFICE-3731 > Project: OASIS Open Document Format for Office Applications (OpenDocument) TC > Issue Type: Bug > Components: Chart > Affects Versions: ODF 1.2 > Reporter: Robert Weir > Assignee: Andreas Guelzow > > Copied from office-comment list > Original author: Regina Henschel <rb.henschel@t-online.de> > Original date: 2011 11:42:56 -0800 (PST) > Original URL: http://lists.oasis-open.org/archives/office-comment/201111/msg00001.html -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://tools.oasis-open.org/issues/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
