Scatter Plot Analysis

The Scatter Plot tool plots one channel against another channel. Using the Scatter tool you can select a predefined template and/or overlay file, select the channels to be displayed, the masked channel to use, the scaling method for the data and the symbol and symbol attributes to use for plotting. The Scatter Plot tool enables you to interactively interrogate the data contained within your database and plot to a map.

The Scatter Plot tool implements dynamic linking between itself and the current database, and through it with any other Scatter or Triplot tool open in the project

A ‘mask’ channel can be used for selecting a subset of data values from the database. When a mask channel is selected, it will be used and updated by the dialog as selections are plotted. A data value is highlighted in red if its corresponding mask value is not a "dummy" value.

You can also categorize the Scatter Plot data with the colour based on a Classification channel.

The Scatter Plot Template (and/or Overlay file) is used to store specific configurations of the scatter tool. Each Template consists of three files:

  1. The Template file, which is a text file that contains information on the channels, scales, titles, etc., as well as the name of the associated overlay file.

  2. The Overlay file is a text file that contains either (i) line/text commands to draw an overlay or (ii) the name of a map file to use as the overlay. In this case, it refers to a map file.

  3. The Map file, which is a Geosoft map containing the overlay map items.

These files are stored in the "…/Oasis montaj/etc" directory. New or modified Templates and Overlays are stored in the "…Oasis montaj/users/etc" directory.

Once the Scatter Plot Analysis tool has been created it is stored as Tools (Geostats/ Geochemistry) in the Project Explorer (on the Tools tab). The Tools (Geostats/ Geochemistry) can be hidden/displayed as necessary (right click on the tool in the Project Explorer and select ‘Hide’ or ‘Show’ from the popup menu). TheTools (Geostats/ Geochemistry) are saved in the project when you close Oasis montaj and will be available automatically, with the same settings, the next time the project is opened.

  • The Scatter Plot Analysis tool can be docked at the top/bottom or sides of the current project window and resized, up to the full size of the screen.
