A chart item is type of report item which is represented in the final report as a chart. Consider this block of data:

Test Value High Low
MorningCortisol 23.0 62.0 5.0
MiddayCortisol 148.0 40.0 3.0
EveningCortisol 14.0 12.0 1.0
MidnightCortisol 9.0 6.0 0.0

The result of defining a chart with the attributes above would be the following:

Using Group Attributes

You need to use a group attribute for the X and the Y axis. The size of both group attributes has to match.

The order on which the attributes are defined in the group attribute is not important. Instead, the chart will use the order defined in the Attribute Editor.

For instance, consider a case with the following attributes:

Test Value
MorningCortisol 23.0
MorningCortisolTime 08:00
MiddayCortisol 148.0
MiddayCortisolTime 12:15
EveningCortisol 14.0
EveningCortisolTime 17:25
MidnightCortisol 9.0
MidnightCortisolTime 23:45

Two Group Attributes are created:

X_Axis MorningCortisolTime (08:00), MiddayCortisolTime (12:00), EveningCortisolTime (20:00) and
MidnightCortisolTime (23:55)
Y_Axis MorningCortisol (23.0), MiddayCortisol (148.0), EveningCortisol (14.0) and MidnightCortisol
(9.0)

Now you can use X_Axis and Y_Axis as data providers in the Chart Item:
