This graph show the daily results of the haem tests for 2009 until Aug 31st

Half monthly averages with a ‘Power’trend line.

Half monthly averages shown as square root of above to indicate area that could be the source of blood.with a ‘Exponential’trend line.

Red Blood Count: red blood cells per microlitre.

The first two graphs show the daily results of the haem tests for from April 2008 to January 2009 (inclusive)

The first is a standard linear function.

The second an inverted logarithmic function.

Logarithmic graphs start at one, hence there is no visual value for ‘one’ and the higher values appear compressed. This has a similar effect of visualising area rather than quantity, better shown in the second of the following two graphs.

The second pair of graphs are based on Half-month Averages.

The first is a simple linear representation of April 2008 to January 2009

The second attempts to show the Relative Area of Source

The square root of the previous figures, the mean haemoglobin count (H), is used as an estimate for the dimensions of the surface area that may be the source of bleeding.
Area = √(H)

Given the source of data and number of significant figures I am using, the first graph cannot show a figure lower that 0.1 other than zero and consequently the square root cannot be lower than 0.3 else zero.

The following is one of the early graphs.

• The red horizontal line indicates the theoretical maximum that the urine testing sticks can define, at approx 200 cells/µlt
• At 300 cells/µlt the blood may be visible??
• The blue mark and blue hatched area is an estimated average for the fortnight before I acquired the testing sticks.

April to June

 

The next page shows graphs of daily averages in monthly periods, although not necessarily per calendar month.
