Select Stamps or Symbols or 2D Bar Chart

Charts may be displayed or printed using either stamps or symbols or bar chart. Use this menu to select your option. You may change to an alternative option at any time.

These options do not affect the way your fertility information is stored in the database. They are only a means to graphically represent fertility in a chart format.

The bar chart is a recent development in fertiltiy chart display. The vertical height of each bar of the chart depicts the level of fertility as recognised in the Billings Method rules. The horizontal dimension is the same as for the other charts, one column per day in seqence by date.

There four levels in the vertical height of the bar chart

  1. Infertile: infertile days;
  2. Wait: days following an interruption to the basic infertile pattern during the pre-ovulatory phase - early day rules apply (the day is either a wait day after intercourse (rule 2) or the days have the count of 1,2,3 attached to the bar corresponding to the wait days of rule 3);
  3. Possibly fertile: days during the pre-ovulatory phase (there has been a change from the basic infertile pattern) and for three days after the Peak;
  4. Peak: Peak day.

The colour of each bar is chosen from the five colours shown in the legend below. The colours represent the types of observations recognised in the Billings Method. The colours are applied in the order of precedence shown in the legend, blood has the highest precedence.

This symbol is supperimposed if intercourse occurs when advised against.

The legend for stamps and symbols is displayed below.

The letter I is superimposed on a stamp or symbol to denote intercourse on the day. If intercourse was advised against on the day (purpose declared in the corresponding fertility history was to avoid pregnancy) then the "I" has a warning triangle background.
