As before, you can alter this configuration once you have published a

report by opening the config.xml file using the Designer. For example, you

might decide to vary the total number of selected areas labelled in the

radar chart or change the colours shown in the chart.

I.4.2. Data Preparation

Preparation of data for this configuration requires only indicators and their

values. By default the radar chart does not display any associate values.

I.5. Making the Chart Read Dataplus XML Files

By default, all of the components in your report will read their data from a

data.xml file (or a data.xml file with supporting theme files). However, you

have the option of making the spine/performance/radar chart read data

from a separate set of XML data files – one for each base geography area.

The main advantage is to increase the performance (speed) of your report.

The report will not need to load all data XML files “up front”. The spine

chart data only gets loaded (one area at a time) when you select an area

following the initial load. The initial load of the report will therefore be

quicker. This performance gain is only likely to be apparent if there are

relatively large numbers of areas (e.g. >200) and/or indicators (e.g. >50).

If you wish to implement this, you will need to configure the spine/

performance/radar chart in your report to read data from dataplus files.

Open the config.xml file for the report, open the properties for the chart and

ensure that the ‘Use Dataplus files?’ checkbox is ticked.

Then add a split column to the Geography and Filters worksheet of your

Excel workbook. The split value for each base geography feature must be

the code of the feature (Figure 181).

Creating Dataplus data files is currently not possible with the HTML

Edition.

The Radar Chart configuration is not yet available as an HTML

Edition.
