The “Name” column should contain the “Name” and “Class Name” information from your foci document
o Copy and paste the author names from the 1st Excel sheet

Add “csvf-section-end” to the last row in Column A (just as you did in the 1st Excel document)
Add “colors” to the last row in Column B
The following values should be entered for all values
o Point-Size: 255
o Line-Size: 2
o Symbol: 1
For each of the Authors entered: choose the colors you would like
o Caret → Layers → Foci →Edit Foci Colors → click “New Color” → Name the new color → shift the
Red, Green, and Blue bars to create your desired colors
To save your colors:
o File → save data file → change to desired name, file type should be “Area Color File (*.areacolor)
→ “Would you like to create a Spec File”→ No
Now match the colors you made in Caret to the values in the CSV sheet
o Helpful hint: create different colors for each author and use the same color for each category
 Thus, if you have “Logical Reasoning” coordinates and “Numerical Reasoning”
coordinates they category will have two distinct colors
This should be what a completed Color Foci File should look like:

First, make sure to open a Spec File
