You can choose the offset type in the Stack tab, when the layer is selected in the left panel.     View larger image If the individual offset is selected, the offset for each data plot can be specified when the plot is selected in the left panel of the Plot Details dialog.

By default, a Stack Lines by Y Offsets graph employs the "Individual" data plot offset type. Each data plot is given its own individual offset setting that can be easily modified in Origin's Plot Details dialog. In addition to this offset type, Origin also supports other types of data plot offsets in multi-curve plots. All supported offset types are listed as follows:

• None
• Cumulative
• Constant
• Auto
• Individual (the default type for Stack Lines by Y Offsets plots)

The ability to adjust the distances between each curve using this offset feature eliminates the need to change the original data. Another benefit of the offset feature is that it can be used to avoid overlap of the curves and to ensure that each curve can be viewed clearly.

The Stack Lines by Y Offsets plot uses a line plot for each set of data. All of the basic properties of the line plots are available in Origin, such as:

• connection type
• color
• width
• style
• pattern fill area

All of these properties can be updated quickly and easily through Plot Details, an intuitive tab-based dialog (details... *).
