Histogram – Options

Use this to set attributes to control the appearance of a histogram.

Graph title

Lets you enter a title for the graph. The title appears centred at the top of the graph.

Title position

You can position the title by selecting the Centre, Left or Right option.

Enclose histogram in box

Select this to draw an enclosing box around the graph.

Title font

This opens the Edit Font dialog that lets you control the font for the title.

Boundaries

Lets you define the boundaries for the bars in the histogram. You can specify the boundaries of each of the bars by selecting Limits and entering a list of the values in the space provided. Similarly, you can specify the width of the individual bins by selecting Bin width and entering the values into the space provided there. Alternatively, you can specify the number of groups by selecting Number of groups or let Genstat define the boundaries by selecting Use data values. In this case the number of groups is either set to be 10, or the integer value nearest to the square root of the number of values in the first data variate if that is smaller.

Lower limit

This specifies the lower limit of the first bar. The default takes the minimum value of the data as the lower limit.

Upper limit

This specifies the upper limit of the last bar. The default takes the maximum value of the data as the upper limit.

X Scale

Specifies what proportion of the space allocated along the x-axis each bar should occupy. The default is 1.0, i.e. no space between the bars.

Y Scale

Specifies the width of the bars for which one unit of bar length represents one unit of data. The default uses the width of the narrowest bar.

Orientation

Lets you specify the orientation of the plot. You can select either Horizontal or Vertical.

Fixed bar width

Specifies whether to plot the histogram with bars of equal width.

Position of bars (Multiple histograms)

For multiple histograms you can control the appearance of the groupings of the bars using this option. Select Stacked if you want the bars to be stacked on top of each other, or Parallel if you want them to be displayed side by side.
