Automatic X range. Select to use the entire range of values in the data along this axis. Deselect to use an explicit subset of values based on your specified Min and Max values. Either enter values or use the arrows. Automatic ranges are selected by default to enable rapid graph building.

• Select By width to create a graph with bars of a fixed width. The number of bins depends on the specified width and the range of values. Indicate the width of the bars in the Bin width option.

Normalize by color. Select to adjust all bars to the same height, displaying overlaid values as a percentage of the total cases in each bar.

Show normal curve. Select to add a normal curve to the graph showing the mean and variance of the data.

Separate bands for each color. Select to display each overlaid value as a separate band on the graph.
