Histogram Plots
Click the Home  New Graph  Statistical  Vertical Histogram or Home  New Graph  Statistical  Horizontal Histogram command to display data in groups or bins. Each bin represents a range of values on the X axis. The height of a bin represents the number of data points that fall within that binâ€™s range. If there is one Y value for each X value in the data set, use the bar chart rather than the histogram. Histograms can be oriented vertically or horizontally. The histogram discussion assumes a vertical orientation. Click the Vertical Histogram or Horizontal Histogram buttons to create histogram plots. 



Vertical histograms display data in a series of groups called bins. 
Horizontal histograms display data in a series of groups called bins.
