Set the interpolation between data points in a visualization

You can set how data points interpolate in an area, line and column, or line visualization.

1. Select the area, line and column, or line visualization that you want to work with.
2. Click the Properties icon.
   

   If you don't see the Properties icon, click the Switch to edit icon.

   
3. To set the way how the data points connect in your chart, select an option from the Interpolation menu:

   Option	Description
   Basis	Interpolates with a curve that uses the data points as control points for the curve. The curve does not touch the points.
   Cardinal	Interpolates with a curve that uses the datapoints as points for the curve. The curve runs through all of the points (default for smooth).
   Linear	Connects all points with a set of straight lines.
   Step	Creates a discrete step up between successive points, where the vertical line starts at the midpoint between the two points.
   Step before	Creates a discrete step up between successive points, where the vertical line starts at the first point.
   Step after	Creates a discrete step up between successive points, where the vertical line starts at the last point.
