Do one of the following:

• Right-click anywhere on the Hits graph and choose Set Graph Display from the shortcut menu Also known as a contextual menu, acessed by right-clicking (or pressing Ctrl+Click, Mac only) over a screen element that appears.
• Press Ctrl+T.
• On the Display menu, choose Set Graph Display.

• Grid spacing harea: These options affect the graph content.
• The Words per hit box allows you to change the sample size of the frequency graph. You can enter any number between 100 and 10,000. An entry of 100 means that each bar represents the number of hits in the 100 words surrounding that point in the search range. A lower number shows more detail and is useful for smaller search ranges. A higher number is better for showing trends across the entire text.

Note To display the frequency of hits at each point in the search range, the graph uses overlapping samples from the search range. Thus, you cannot count the number of hits in an entire book or section from the graph. Rather, the graph should be used to spot trends in usage through the search range. In the Set Graph Display for Reference tools, this item is Verses per hit with limits of 5 to 2000.

• Display items: These items affect how the graph is drawn, and make the most difference when there are fewer sample points.
• Bars displays a vertical bar at each sample point.
• Lines draws a line connecting the sample points.
• Areas fills in the shape under the line.
• Superimpose as items: These items apply to display of multiple graphs.
• Overlay uses the same baseline for each graph with the oldest graph appearing behind newer graphs but still visible through the transparent colors.
• Stack creates a separate graph for each result, one above the other.
• Show sum of hits adds another graph with the totals of the graphs currently showing. This item can be selected with Stack or Overlay.
• Graph appearance area
• Show grid adds a light gray grid to the background.
• Use black background changes the graph background to black; this looks particularly good in presentations or a slide show.
• Graph colors area: Color pop-up menus let you customize the color of each displayed graph. Up to seven different graphs (and the sum of the hits) can be kept in the Graph tab at one time, with the color of each graph set by a numbered color pop-up menu item.
  
  To change the color of one of the graphs, simply choose a new color from the corresponding pop-up menu.

Note The numbers beside the color pop-up menus refer to the current number of each graph. Therefore if you have two graphs showing, and you clear the first (earliest) graph, the color of the second graph changes to the color of the first pop-up menu setting.
