Step
1 Data option is selected in Systat. |
Step
2 Input file is selected (rockbox.txt). |
|
Step
3 Data window opens automatically so data can be viewed and checked (NOTE: “Ag” in the first column refers to a rock unit; “AG” in the second column refers to an element (silver). All values are percentiles of total data set, previously calculated). |
Step
4 The Box Plot option is selected. This could also have been selected using the icon circled in the previous frame. |
|
Step
5 As(1) is selected as the y-axis (number 1 in parentheses indicates initial (1978) analyses by AAS; samples were subsequently reanalyzed by INAA). Unit is selected as the x-axis (dollar sign indicates alphanumeric or “string” variable) |
Step
6 Preliminary result. Double-clicking on the image will open the graphics window (next frame). |
|
Step
7 Graphics window. Image can now be saved for future use. |
Step
8 File saving options. In this case, a Windows metafile gave the most satisfactory image when imported into MS-Word. |
