Customizing a user defined graph, the three values of the first test are all centered, one on top of the other, in the middle of the graph. One test value can not be distinquished from the other.
Common, layman Item Names were used rather than decipher the assortment of complicated "standardized measurement-type names' offerred in the 'comprehensive list'. These are the entries: RBC 3.71 milli/uL, Hemoglobin 13.7 g/dL and Hematocrit 39.5 %. Notice each test has a different 'Unit'.
Maybe when the second and third tests are added to the record the first test values will separate. However, another user defined graph I made with different blood tests has the same problem with three of four values of the first test stacked on top of each other. On this graph the three stacked values have different 'Units', while the one value that is not stacked has the same 'Unit'(%) as one of the stacked values.
It appears the program centers the values different Units of the first test mid-range on their vertical scale but doesn't permit the values to separate from that absolute position when other tests are added. Just a guess.
