Nye grafiske funksjoner

Visually differentiate groups within your data and achieve the desired graphical aesthetic with more Line Types and Fill Patterns
New 3D Mesh Plots with Contour Projections enhance the visualization of three dimensional data coordinate values
SigmaPlot 10 automatically interpolates and graphs irregularly spaced three-dimensional data to quickly generate smooth and highly accurate mesh and contour plots from any 3D data sets
Polar Plot angular direction support allows users customize the angular direction that best fits the conventions for their data
New axis scales for two and three-dimensional graphs including Weibull axis scale, Reciprocal axis scales, and Arrhenius scales
Easier manipulation of the graph elements even with object is buried under other items
Quickly customize the size and position of multiple graphs and graph page object
