Grapher 6 is a 2-D and 3-D graphing package that allows users to create contours or a 3-D surface from any XYZ data file, an existing Surfer grid file, or a USGS DEM file. Users can color fill the plots, overlay contours on surface plots, or combine them with other graph types to effectively present 3-D data. This package automatically creates confidence intervals on line/scatter plots, as well as create 2-D vector plots. Users can also select any confidence interval necessary and display it automatically on the graph. Multiple confidence intervals can also be shown. The new vector plots display vectors of the data using an XY starting position and either magnitude and direction or an XY ending position.
