new chart: 3D View specification line 26 differs from implementation
Last modified: 2013-02-24 21:20:46 UTC
in Line 26 you can read that "Leaving the 3D View dialog with OK-button makes the changes permanent" but that isn't true. If you enter -180 (X rotation),180 (Y rotation) and 100 (Z rotation) and press OK on a 3D chart ("realistic"). If you open with Format / 3D View the dialog again you see 0,0,-80 (X-, Y-, Z-rotation). - For A11Y a hard work because they won't be able also in the new chart to create a chart with values they can verify. - Usability is very unimpressive because the expectation differs totaly from that dialogs in the rest of the office application. + The view seems to be the same with the destroyed values in the dialog.
added keywords
As one issue should concentrate on one problem only I handle the difference of specification and implementation here and adjusted the keywords accordingly. After discussion with mmp I updated the specification thus it now explicitly allows the change of the angles after closing with OK and reopening the dialog ( see section 4.1.1 Note about the concrete angle values ). This is necessary as the ODF Fileformat does not allow to save the three angles separately. Instead only a resulting matrix can be stored. If the angles are recalculated from the matrix the solution is not unique, but the resulting visible rotation is the same.
-> Jogi: The updated specification is online: http://specs.openoffice.org/chart/Chart3DViewDialog.odt
Read "4.1.1 Note about the concrete angle values From the three angles a transformation matrix is calculated and stored. When recalculting angles from the matrix the solution is not unique, thus it can happen that you get different values for each of the angles when reopening the dialog. But the resulting transformation will have the same visible effect." OK
