Figure 187

The regional/national average is shown as a horizontal green line across

the chart. The yellow and red curves are the upper and lower 95% and

99% confidence limits plotted for the regional/national average. Points that

lie above/below the upper/lower curves are significantly different from the

regional/national average. Points that lie within the funnel are not

significantly different from the regional/national average.

There is only one ‘Data’ button and this is used by the end-user to change

the indicator values in the map. The indicator values shown in the map are

also plotted on the Y axis of the chart. The X axis values must be supplied

as an associate:

FUNNELX – the X axis values for the chart. Typically, these are

sample/population sizes. In public health for example, it is common to

show Standardised Mortality Ratios (SMRs) on the Y axis and the

expected number of deaths on the X axis.

The required data structure is shown in the ‘iadatasheet’ worksheet of the

workbook called IAworkbookBubblePlot_FunnelPlot_Flash.xls. This is also

in the ‘workbooks’ folder of your InstantAtlas installation.

Figure 188

The IA6 Funnel Plot configuration of the HTML Scatter Plot template

uses associates called ‘xValue’ and ‘yValue’ as data sources for the

funnel plot axis.

A workbook called IAworkbookBubblePlot_FunnelPlot_HTML.xls is

provided as an example within the ‘workbooks’ folder of your

InstantAtlas installation.
