Last Update: 3/16/2020
Origin 2020b newly supports plotting 3D side-by-side Bar graph by one-click: Plot: 3D: XYY 3D Side by Side Bars menu.
If you have already created a normal 3D Bar graph from XYY data, you can double click on the graph to open the Plot Details dialog, and select Side by Side Bar Style checkbox on Miscellaneous tab of Layer level to make bars side by side.
Please refer to Help: Learning Center > 3D Bar Charts - 3D XYY Grouped Bars from Non-Zero Base.opju for a detailed example.
