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.

Adding Value(s)

You can add more than one Measure to the Y Values field by dragging and dropping the required measures.

Click on the Settings option to change the required summary type from the available summary types shown in the Settings menu.

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

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

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

You can add more than one column from the Dimensions field to the Y Values field.

Adding Columns

You can add more than one value to the Columns field.

The area chart will be rendered in this manner.

You have the option to change the settings.

Renaming fields

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

Sorting data

You can sort the dimension data using the Sort option under the Settings menu list. To apply sorting to the data, refer to the Sort.

Filtering data

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

To view all records, click on Show All Records.

Similarly you can add the Measures and Expression Columns into column field. Add more than one value to the Columns field, an alert message will be shown. Click Yes to enable the option.

NOTE: If you click No, a single value will be added to the Columns field.

The selected view of the chart region is drilled.

Adding Rows

You can drag and drop the Dimension into the Rows field.

If necessary, you can apply a filter and sort option to the rows field.

This will render an area chart in a series.

Hidden Column

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

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

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

Linking

The primary use of hidden columns is for linking. When configuring hidden columns, we can observe that the fields set in hidden columns are listed in the linking section. By configuring the column in the linking section, we can pass the corresponding column value as a 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 number of Team Name played as a URL parameter but do not want it to affect the visualization, we can configure the Team Name in the hidden columns and include them in the link.

Filtering

You can use hidden columns to filter data in the visualizations. Configure hidden columns and click the filter icon below.

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

Now, we can see in the image below 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 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 information icon in the Hidden Column section.

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

If we configure lower hierarchy data (Player Name) in hidden columns compared to column and row field data, the data configured in the widgets gets duplicated, and each individual column is split based on the hidden column field. This affects the visualization of the chart, as you can see in the image below.

How to format area chart?

You can format the area chart to better illustrate the view you require by using the settings available in the Properties tab.

To format an area chart, follow these steps.

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

However, there are times when we need to invert the axis and display negative values at the top and positive values at the bottom. For example, when binding temperature data to the chart and wanting to display negative values at the top, we can utilize this property.

When this property is enabled, the chart will display negative values on the top and positive values on the bottom.

Axis Range Settings

This allows you to manually set the minimum, maximum, and interval values of the primary value axis through the Axis Range Settings dialog.

It will be reflected on the primary value axis of the chart.

Parameter Support in Axis range:

This feature allows you to dynamically set the minimum, maximum, and interval values of the primary value axis through the Axis Range Settings dialog by using the values of the dashboard parameters. Only number-type dashboard parameter values are allowed in the axis range properties. You can create multiple types of dashboard parameters.

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

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

Single Parameter Value:

A single value is stored in this type of parameter.

1. Create a dashboard parameter in the number type as shown below.

Click on the axis range settings dialog and enter @ in the textbox. Select the parameter value (Numeric parameter values are only allowed in the minimum, maximum, and interval).

Now the parameter value is reflected in the chart axis.

Range Parameter Value:

If you want to establish the same ranges in multiple cases, create the parameter value for the range type. This type of parameter includes the start and end values.

1. Create a parameter of type range.

2. Click the axis range settings dialog and enter @ in any textbox (minimum, maximum, and interval). The range parameter is split into start and end parameters. 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.

2. Click on the axis range settings dialog and enter @ in any textbox (minimum, maximum, and interval). Then, select the parameter value.

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

Use Default Palette

This option allows you to apply the default color for chart series.

By toggle off the Use Default Palette option, the Color Mapping Type will be shown.

Color Mapping Type

Using the Color Mapping type, you can apply the colors to the series either based on data or index.

Data

It allows you to apply color to chart series based on data. If you want to assign a specific color to specific data (e.g., Violet for 2021, Sky Blue for 2022, and green for 2020), you can use data-based color mapping. The default Color Mapping Type is Data.

Index

It allows you to apply color to chart series based on the Index, so that the colors remain consistent even if the data is changed. It shows only 15 different colors; after that, the colors will repeat from the ones above.

For example, if you are displaying the countries based on the increasing order of the case count, index-based color mapping will be useful for setting the colors based on the rank. For instance, the top-ranked country can be assigned the color red, and this red color will be maintained for the country with the largest case count.

Note: We prefer to use index-based color customization only for a minimum amount of data (up to 15 series).

Font settings
