Propiedades de liña suave

Nas gráficas que mostran liñas (tipo liña ou tipo XY) pode escoller mostrar curvas en vez de liñas rectas. Dispón de opcións que controlan as propiedades desas curvas.

Line properties

Line type

Seleccionar Spline cúbico ou Spline B

Estes son modelos matemáticos que influencian como se mostran as curvas. As curvas créanse unindo segmentos de polinomios.

Cubic Spline interpolates your data points with polynomials of degree 3. The transitions between the polynomial pieces are smooth, having the same slope and curvature.

B-Spline uses a parametric, interpolating B-spline curve. Those curves are built piecewise from polynomials.

Resolution

The Resolution determines how many line segments are calculated to draw a piece of polynomial between two data points. You can see the intermediate points if you click any data point.

A higher value leads to a smoother line.

Degree of polynomials

For B-spline lines optionally set the degree of the polynomials.
