Origin 2017 3D Graphing Improvements

JIRA	SUMMARY	DETAILS
ORG-3127 ORG-7365	3D Bar plot different shape for XYY and XYZ bars
ORG-14444 S1	Dropline Direction Control in 3D graphs
ORG-14444 S2	Origin doesn't support 3d bars in projected planes. But user can turn on dropline and set big line thickness to make the dropline looks like bars. But in previous versions, dropline end cap will show as semicircle. Orgin 2017 added system variable @lc3p to control it.	@LC3P=-1, Default. Old behavior. Semi-Circle @LC3P= 0, compatible with OLineCap. Round @LC3P= 1, Square @LC3P= 2, Flat With this feature, users are able to use thick dropline in projection plane as 3D bars on projection.
ORG-13301	Group plots in 3D	The following plot types are supported 3D XYZ Scatter 3D XYZ Bars 3D Matrix Bars So user can easily set group increments of plot attributes
ORG-8720	Support stacked XYY 3D bar graphs	The following plot types are supported Stacked XYY 3D Bars Stacked XYY 3D Bars plot with subgrouping Clustered XYY 3D Bars plot with subset https://dl.dropboxusercontent.com/u/69449127/WikiImg10/94_3D_Stacked_Bar.png Improve stack plots with the following features Display column/bar plot by sorted order; Normalize to Percent for Cumulative/Incremental; Error bar for stack and percent stack. Wall & Ribbon support stack as bar
ORG-14245	Support all 2D objects in 3D OpenGL graph, such as	Table, such as result table after fitting Image Rectangle, Circle Bubble Scale OLE object
ORG-14500	Enable Bubble Scale for OpenGL(3d Scatter)	Size formula not only works for 2D graphs but also works for 3D OpenGL graphs, user can specify symbol size using some math expression based on values in Size column.
ORG-14699	Enable Reconstruct Legend toolbar button for 3D plot	Users are able to add and edit legend for 3D plots using Reconstruct Legend toolbar button.
ORG-14629	Support 3D Stack Bars with multiple objects from matrix sheet	Support plotting all matrix objects together from active layer for 3D Stack Bars plot.
