This illustration shows the Heap Graph. It is a two-dimensional graph that plots heap information in real time. At the top of the image is a arrow that controls displaying and hiding the graph. In this example, the arrow points down indicating that the graph is diplayed. To the right of the arrow is the title text, "Heap". The actual graph starts at the left edge of the image, below the title text and arrow. The Y (vertical) axis shows the percentage of heap 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 biitons is a check box labeled "Freeze scrolling".
