Radar Chart
This chart type belongs to PowerCharts XT.
A radar chart (also known as a spider chart) is a visual interpretation of data bearing multiple dimensions. With the radial grid like structure, the chart displays the values of different categories on its axis. Radar charts are primarily used as a data comparison tool to visually correlate and contrast entities over its diverse aspects such as growth against benchmarks, progress over several criteria, etc. Radar charts can be plotted for a single dataset (single-series radar chart) or multiple datasets (multi-series radar chart).
Common application areas for radar charts include:
Business performance
Quality analysis
Product comparison
As an example, we will create our first radar chart that plots the results of a customer feedback survey based on five categories. The radar chart will be used to compare the results for each category and determine what service needs improvement.
To create a radar chart follow the steps given below:
Specify the chart type using the
typeattribute. To render a radar chart, setradar.Set the container object using
renderAtattribute.Specify the dimension of the chart using
widthandheightattributes.Set the type of data (JSON/XML) you want to pass to the chart object using
dataFormatattribute.
In the JSON data:
Set the attributes and their corresponding values in
"<attributeName>": "<value>"format.Specify the label for a data item using the
labelattribute. This attribute belongs to thecategoryobject, which in turn belongs to thecategoriesobject.Specify the value for a data item using the
valueattribute within thedataobject.Specify the name of the series for a dataset using the
seriesnameattribute. This attribute belongs to thedatasetobject.
For a detailed list of attributes, refer to the chart attributes page of multi-series radar chart.
The radar chart created will look like as shown below:

Now, we will create a multi-series radar chart for the budget analysis for the current month for the five key departments at a store. For each department, we will plot the allocated budget and the actual cost. This will help to determine how accurate the budget estimation at the beginning of the month was - whether the budget was over-allocated, under-allocated, or correctly allocated.
The data structure to create the multi-series radar chart is same as that of radar chart.
The multi-series radar chart thus created looks like this:

"chart": {
"caption": "Budget Analysis",
"subCaption": "Current month",
"numberPreffix": "$",
"theme": "fusion",
"radarfillcolor": "#ffffff"

}

}
