The actual graph starts at the left edge of the image, below the title text. The Y (vertical) axis shows the percentage of thread usage, by 10s, between zero and 100. The X (horizontal) axis shows time increments. To the right of the graph is a legend that indicates which color applies to which attribute. Beneath the legend are two buttons labeled from left to right "Add" and "Remove". Under the buttons is a check box labeled "Freeze scrolling".
