## Histogram Options for Continuous Variables

Histogram

Shows or hides the histogram. See Histograms.

Replaces the histogram with a shadowgram. To understand a shadowgram, consider that if the bin width of a histogram is changed, the appearance of the histogram changes. A shadowgram overlays histograms with different bin widths. Dominant features of a distribution are less transparent on the shadowgram.

Note that the following options are not available for shadowgrams:

Std Error Bars

Show Counts

Show Percents

Vertical

Changes the orientation of the histogram from a vertical to a horizontal orientation.

Std Error Bars

Draws the standard error bar on each level of the histogram using the standard error. The standard error bar adjusts automatically when you adjust the number of bars with the hand tool. See Resize Histogram Bars for Continuous Variables and Standard Error Bars.

Set Bin Width

Changes the bin width of the histogram bars. See Resize Histogram Bars for Continuous Variables.

Histogram Color

Changes the color of the histogram bars.

Count Axis

Adds an axis that shows the frequency of column values represented by the histogram bars.

Note: If you resize the histogram bars, the count axis also resizes.

Prob Axis

Adds an axis that shows the proportion of column values represented by histogram bars.

Note: If you resize the histogram bars, the probability axis also resizes.

Density Axis

The density is the length of the bars in the histogram. Both the count and probability are based on the following calculations:

prob = (bar width)*density

count = (bar width)*density*(total count)

When looking at density curves that are added by the Fit Distribution option, the density axis shows the point estimates of the curves.

Note: If you resize the histogram bars, the density axis also resizes.

Show Percents

Labels the proportion of column values represented by each histogram bar.

Show Counts

Labels the frequency of column values represented by each histogram bar.
