== EM.Cube's Basic Graph Types ==
[[EM.Cube]] provides a Python-based graphing utility that is used to plot a number of 2D and 3D graph types:
# Cartesian Graph
# Bar Graph
# Polar Graph
# Polar Stem Graph
# Smith Chart
# Colorgrid Map
# Contour Plot
# Filled Contour Plot
# Surface Plot
Cartesian graphs are the most general type of graphs and can be used to plot real, complex and angular data. Any data file with a '''.DAT''' extension can be plotted as a Cartesian graph in EM.Grid. When you select a data file in the Data Manager's 2D tab and click the {{key|Plot}} button, it opens EM.Grid and plots the contents of the selected data file.
A bar graph is a special type of a Cartesian graph where the data points are not connected with continuous lines. They are rather represented by vertical bars stemming from the horizontal axis. Polar graphs are used exclusively to plot angular data. The independent variable is represented by an angle, while the dependent variable is represented by the radius from the origin of coordinates. A polar stem graph is a special type of a polar graph where the data points are not connected with continuous lines. They are rather represented by radial bars stemming from the origin of coordinates. Smith charts are used exclusively to plot complex data. If the complex data are normalized (with a unit maximum magnitude), then the entire graph will be enclosed inside of the Smith chart. Intensity maps are used exclusively to graph matrix data. A data point on an intensity map represents the value of a dependent variable for a certain (X,Y) coordinate pair corresponding to a(i,j) index pair in the matrix.
