Alongside the Log screen, the Scatter Screen forms the heart of TSG's data analysis capabilities. The Scatter Plot screen allows the user to assign any scalar values to X or Y axes and a third scalar to the colour scale (Z) in up to 16 simultaneously displayed  graphs. Graph windows can also display frequency histograms for any selected scalar.

As many TSG datasets are composed of a variety of data types including spectral data, geochemistry and coordinate data, the Scatter Plot screen is designed to allow you to display and analyse all of these data types as an integrated data set. In addition, each plot window in the Scatter screen is linked so that the selected data point/sample/spectrum in one screen is highlighted in all the other screens currently on display.

By assigning coordinate data to X and Y axes the Scatter Plot screen can be used to display sample spatial distribution in plan or section. This allows the spatial distribution of geochemistry and alteration mineralogy to be simultaneously investigated. This functionality combined with the Floater window also allows the simultaneous analysis of hundreds or even thousands of spectra while at the same time allowing you to keep track of individual sample spectral or mineralogical characteristics.  Similarly, using RL and Easting or Northing data for down hole samples can allow you to plot a section of holes in the Scatter screen with their data points coloured by a given scalar in your TSG file.

There are a number of advanced analysis tools available in the Scatter Plot screen such as the lasso option, which allows you to select a cluster of data points and view where these samples occur in all other displayed plots.  Plots can also be filtered using the Scope option, to display only those samples from a given class (such as a given lithology, mineral assemblage or section).

In the Scatter Plot screen shown in the figure, four plot windows have been set up. The top two plot windows are being used to display coordinate data with the data points coloured to show various geochemical and spectral data. The plot window at bottom left is being used to display a histogram while the window a bottom right is being used in scatter plot mode to investigate correlations between certain geochemical and spectral parameters.
