Chart Types
Chart Types define the sort of patient data that can be plotted together on a Qualifier_Chart. Any number of chart types can be defined.
The chart type maintenance window has two panes.
* Chart Name * The top pane is where chart names are maintained. Chart names should be unique, clear and unambiguous.
* Qualifiers * The bottom pane defines the Qualifier Types that are to be graphed together on the chart.
* One line is added to the chart for each qualifier.
* Only numeric qualifiers can be graphed.
* Any number of qualifiers can appear on a chart, though only two different
measurement units can appear on a single chart. This is because the first unit
is placed on the left 'Y' axis and the second one (if any) is placed on the
right 'Y' axis.
