In a chart that displays lines (Line type or XY type), you can choose to show curves instead of straight lines. Some options control the properties of those curves.
To access this command... |
Select Cubic Spline or B-Spline.
These are mathematical models that influence the display of the curves. The cubic spline line passes through all points, while the B-spline line connects the first and last point and passes by the intermediate points.
Optionally set the resolution. A higher value leads to a smoother line.
For B-spline lines optionally set the data points order.
