The Polar Chart visualizes data in terms of values and angles. It provides options for visual comparison between several quantitative or qualitative aspects of a situation.
These types of charts are categorized under the Distribution
category in the item panel.
Drag and drop the polar chart from the item panel into the design area.
Now, the polar chart will be rendered in the design area and the chart properties will be listed in the properties panel.
To present data in the chart, create a dataset and bind data to the chart data region. In this designing section, the following json data is used for dataset creation.
[
{
points: [
{ Month: 'Jan', Celcius: -7.1 }, { Month: 'Feb', Celcius: -3.7 },
{ Month: 'Mar', Celcius: 0.8 }, { Month: 'Apr', Celcius: 6.3 },
{ Month: 'May', Celcius: 13.3 }, { Month: 'Jun', Celcius: 18.0 },
{ Month: 'Jul', Celcius: 19.8 }, { Month: 'Aug', Celcius: 18.1 },
{ Month: 'Sep', Celcius: 13.1 }, { Month: 'Oct', Celcius: 4.1 },
{ Month: 'Nov', Celcius: -3.8 }, { Month: 'Dec', Celcius: -6.8 }],
Country: 'Warmest'

Refer to the Create Data section for more information. Here, we are going to create a dataset using JSON inline data to design the report.
The Polar Chart needs a minimum of one value element and one column element to showcase. The measure or expression field that you want to analyze can be dropped into the Y Value(s)
section. The dimension for which you want to categorize the measure can be dropped into the Column
section. To categorize the measure based on a series, drop the respective dimension into the Row(s)
section.
To configure data into a polar chart, follow the steps:
To bind data to a chart report item placed in the design area, focus on that report item.
Click the Properties
icon in the configuration panel, the property pane opens. Now, switch to the DATA
tab.
The available data in the report will be listed in the dropdown, choose a data in the dropdown list.
The numeric columns and numeric expressions are listed under the Measures
section; other types of columns and dimension expressions are listed under the Dimensions
section.
Drag and Drop Measure Element:
Select and drag the numeric column (measure element) or the numeric expression column from the Measure
section and drop it in the Y Value(s)
section.
Now, the report item design will look like below:
Aggregate Options:
Click the Settings
icon (highlighted below) to open the aggregation type dropdown list.
You can set the aggregation type by which you can compute the selected column.
Drag and Drop Dimension Element:
Select and drag the dimension element from the Dimensions
section to measure against any of the selected numeric column(s) in Y Value(s)
section, and drop it into the Column
section.
Now, the report item design will look like below:
Grouping:
You can group the added column element with another column by adding the respective dimension element into the Row(s)
section.
Now, the report item design will look like below.
Formatting Column and Row(s) sections:
You can also Filter, Sort, or Group the Column or Row(s) sections using expressions.
For example, here the Month
field is sorted using =Month(cdate("1-" & Fields!Month.Value))
expression.
You can format the polar chart for better illustration of the view that you require, through the settings available in the Properties
tab.
To format a polar chart, follow the below steps:
Drag and drop the polar chart into the design area and resize it to the required size.
Configure the data for the polar chart.
Focus on the polar chart and click the Properties
