The bar chart version of the Overview graph shows you how many calls each day received scores based on the application's categories.

1. Choose "Hit/Miss" from the drop-down menu to display only hit/miss score data on the graph, or choose "Coverage" from the drop-down menu to display more-nuanced coverage data.

2. The key above the Overview graph assigns a color to each top-level category. Each day's vertical bar is divided into categories using these colors. Select a color in the key to hide that category's data so that it is not displayed in the graph.

3. Hover the pointer over a division to see a tool tip that displays the name of the category, the date represented by the bar, the percentage of files that received scores from that category on that day, the number of files that received scores from that category on that day, and the total number of files recorded that day.

4. The total height of each bar is measured against the vertical axis, and is the total of all the percentages that day. The relative heights of the bars over time enable you to compare the effectiveness of the application on each day.

The line graph version shows you the effectiveness of each category over time.

1. The key above the Overview graph assigns a color to each top-level category. Each category is represented as a line that follows the percentage of files each day that received scores from that category. Select a color in the key to hide that category's data so that it is not displayed in the graph.

2. Hover the pointer over a single-day point in the graph to see a tool tip similar to the one described for the bar chart.

Selecting a graph division in the bar chart (or a single-day point in the line graph) also filters the view below to only those files that match the same date and that received scores in the selected category.
