Radar/Polar Chart

A Radar/Polar chart is a graphical method used to display multivariate data in the form of a two-dimensional chart. It utilizes three or more quantitative variables represented on axes that originate from a common point.

How to configure the table data to Radar/Polar chart?

The Radar/Polar chart requires a minimum of 1 value element and 1 Column element to display the data. The chart can be configured by dragging and dropping series into the Value section and variables into the Column section.

Please follow the steps below to configure the data for the Radar/Polar chart:

1. Please drag and drop the Radar/Polar chart widget onto a canvas and resize it to your desired size.

2. Click the Data Source button in the configuration panel.

3. Click the CREATE NEW button to initiate a new connection from the connection type panel.

4. In the connection type panel, click any of the listed connection type buttons (Here, the Excel Connection type is selected for demonstration).

5. In the NEW DATA SOURCE configuration panel, fill in the connection type and related details. Then, click the Connect button.

6. Drag and drop your preferred table or view from the left pane from the data design view, click the Save button.

7. Click on the Properties button in the configuration panel to open the property pane. Then, switch to the ASSIGN DATA tab.

8. The ASSIGN DATA tab will be opened, displaying the available measures and dimensions from the connected data source.

You can add the required data from the Measures and Dimensions into the required field.

Adding Value

You can drag and drop the Measures field into the Value section.

You can add a maximum of six series into the Value field.

Click on the Settings option to change the name by accessing the Rename option and selecting the required summary type from the available summary types shown in the Settings menu.

Filtering data

You can filter the data to be displayed in the chart by using the filter. For more details, please refer to the filter.

Formatting data

You can format the data to be displayed in the chart by using the format option. For more details, refer to the measure format

Removing fields

To remove the added value fields, click the highlighted button.

Adding Column

You can add a single value into the Column field. It can be either a Dimension or Measure.

Renaming fields

The field names that have been configured can be edited by using the Rename option provided in the settings menu.

Sorting data

You can sort the dimension data by using the Sort option in the Settings menu list. To apply sorting to the data, please refer to the Sort function.

Filtering data

You can apply filters by selecting the “filters” option in settings. For more details, refer to the filter.

Now the Radar/Polar Chart will be rendered as shown below.

Hidden Column

Hidden columns are useful in cases where we do not want the fields to participate in the visualization, but only to be used for linking, filtering and view data.  

We can configure both measure and dimension fields into the hidden column. For measures, we will have all the settings we have for measure fields except formatting and filtering.

In the case of dimension fields, we will have the following options only. For date fields, we will have all available types except sorting, relative date filter, settings, and filters.

Linking

The primary use case of hidden columns is linking. By configuring hidden columns, the fields configured in hidden columns are listed in the linking section. By configuring the column in linking, we can pass the corresponding column value in the linking parameter.

Measure Based Example: If we want to pass the number of matches played as a URL parameter but do not want it to influence the visualization, we can configure the matches in the hidden columns and incorporate them into the link.

Dimension Based Example: If we want to pass the team name as a URL parameter but do not want it to influence the visualization, we can configure the team name in the hidden columns and incorporate them into the link.

Filtering

You can use hidden columns to filter data in the visualizations. To configure hidden columns, click on the filter icon below.

Next, click on the Custom button highlighted in the filter configuration dialog image below. This will display a list of all the fields configured in the widget. Keep the field configured in the hidden column and remove the other fields, then click the Update button.

Now, in the image below, you can see that the data is filtered based on the hidden column field instead of the actual column that we bound in the widget. 

For more details about filtering the widget data, refer to the Cross Filter Configuration documentation.

View Data

You can view the data in the hidden columns in the underlying data view. This is useful for checking the data in more detail and can help you identify any issues with the data.

NOTE: We do not recommend configuring lower hierarchy data in hidden columns, as indicated by the info icon in the Hidden Column section.

The below chart displays the goals by each team without hidden columns.

If we configure lower hierarchy data (Player Name) in hidden columns compared to column filed data, the data configured in the widgets gets duplicated, and individual columns are split based on the hidden column field. This affects the chart visualization, as can be seen in the image below.
