The Summary screen is designed to give you an overview of your dataset and is by default the first screen you will see when you open or create a new TSG dataset.  It is particularly useful for gauging the degree and type of variability within large datasets, and can now also summarise the broad mineral groups down hole in spatially related data sets.  This screen consists of two subscreens, the Overview Assemblage Histogram and the Spatial Assemblage Histogram.  By default these are presented in the upper and lower plots, respectively, but the user can change what is displayed in each plot using the Plot Type control drop down list.  To select one of the plots to make it the active plot, all you need to do is to click on it.

The Overview Assemblage Histogram is driven by the automated spectral analysis program The Spectral Assistant (TSA v 6.3) and displays histogram bars relating to the number of minerals identified in the data set as well as the frequency of the occurrence of those minerals.  TSA is designed to give you an overview of the mineral species or classes likely to be present in your dataset.  This plot can be a useful indication of the assemblages or suites of minerals present (e.g. phyllic, propyllitic, argillic, felsic, mafic, ultramafic, etc.), before launching into the detail analysis of a large number of individual spectra.

The Spatial Assemblage Histogram, also displays the results of TSA, but allows the user to control the x-axis scalar which can be any numerical scalar but makes more sense if it is a spatial scalar such as a Depth scalar or Index scalar.  If a "Depth (m)"  scalar is present in the data set (which would normally be automatically created on import of a HyLogging data set) then TSG will use this by default. If this scalar is not present, then the Index scalar is used by default.  The user can create a depth scalar at any time. For example, by importing the depth data for a set of hand measured spectra and then use this information in this display.
