A Line Chart displays a sequence of line segments that are sequentially connected. Line charts are usually used to show a trend or how a value contributes to a trend total (stacks), usually over time or other X measurement. Following is a description of the line chart settings:

Classical  Displayed in both 2D and 3D. The X dimension type is always Categorical.

Piles series on top of each other and scales each pile to 100%. 
XY Scatters  Displayed in both 2D and 3D. The X dimension type is always Numeric.

The first in chart defines the stack X position. Next in chart are piled on top. Each pile is scaled to 100%. 
XYZ Scatters  need 3D to be displayed correctly. The X and Z dimension types are always Numeric.

The first in chart defines the stack XZ position. Next in chart are piled on top. Each pile is scaled to 100%. 
Shape  defines the shape of the line segments. Possible values are: Line, Tape, Tube and Ellipsoid.
Depth Percent  controls the size of the tape shape in all subtypes except for XYZ scatter.
Size  controls the size of the shape in all XYZ scatters.
Sampling Mode  controls whether the line uses sampling. When using sampling the line will filter very close individual line segments and display a single line segment instead. This reduces the number of visual line segments and therefore leads to improved performance. When using sampling the line series will not regard settings for markers and data labels, individual appearance styles and shadow. Possible value are:
Auto  The line series uses sampling only when the number of data points is large.
Enabled  The line series always uses sampling.
Disabled  The line series does not use sampling. This is the default.
Sample Distance  controls the precision of the line series when it aggregates adjacent line segments. The precision is specified in points.
