Area Chart

The Area Chart enables you to compare values for a group of unordered items across different categories by using filled curves that are arranged vertically.

How to configure the table data to area chart?

An Area Chart requires at least one value element and one column element in order to be displayed. The measure or expression field that you wish to analyze can be placed in the Y Values block. The dimension that you want to use for categorizing the measure can be placed in the Columns block. If you want to categorize based on a series, you can also place the corresponding dimension in the Rows block.

The following steps explain how to configure data for an area chart:

1. Please drag and drop the area chart widget onto the canvas and resize it to your desired size.

2. Please 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 on any one of the listed connection type buttons (here, the Microsoft SQL connection type is selected for demonstration).

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

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

7. Click the Properties button in the configuration panel to open the property pane.

8. Now, switch to the ASSIGN DATA tab.

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

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

2. Range parameter value.
3. Data source field based parameter values.

For more details about dashboard parameter, refer to the Dashboard parameter documentation.

The value of the first textbox is stored in the start parameter, and the value of the second textbox is stored in the end parameter. Select the parameter value (only Number type parameter values are allowed).

3. The value of the parameter is reflected on the chart axis.

Data Source Field Based Parameter Value:

1. Create a parameter in the data source type, wherein you can choose any field. The value of the parameter will be determined by the selected field value.
