Histogram Scale, Limits and Options

The scale for each of the individual histograms is defined by choosing the type from the pull-down list.

Some of the scales need limits to be added. Text boxes will appear to indicate this when the type is chosen.

The scales available include :-

• Min to Max, Zero to Max and Zero to Min - The histogram is drawn to a calculated scale which depends on the values.

• Red/Black - Effectively two histograms are drawn; a black one if the value is positive and a red one if it is negative. Both are to the same scale.

• Log10 - 2 Decades and Log10 - 4 Decades - The histograms are drawn on a logarithmic basis.

• Fixed - Two fixed limits must be entered.

• Box Top and Box Bottom - Used together these two scales can be used to create a box or range.

  These might be used with the largest and smallest values of a field to create a box in say which other fields are shown.

The options can also be set to further modify how the histogram will appear.
