Stacked Area Chart

The Stacked Area Chart allows you to compare multiple measures by displaying filled curves that are stacked vertically, one after the other.

How to configure the table data to stacked area chart?

A Stacked Area Chart requires a minimum of 1 value element and 1 column element to be showcased. 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 to categorize the measure can be placed in the Columns block. If you want to categorize based on a series, you can also place the respective dimension in the Rows block.

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

1. Please drag and drop the stacked area chart onto the canvas, then 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 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 the Connect button.

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

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

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

9. You can add the necessary data from the Measures and Dimensions into the designated field.

Adding Value(s)

You can add more than one Measures into the Y Values field by dragging and dropping the required measure.

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

Filtering data

You can filter the data that is displayed in the funnel chart by using a filter. For more details, 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

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

You can add more than one column from the Dimensions field to the Value(s) field.

Adding Columns

You can add more than one value into Columns field.

The stacked area chart will be rendered like this.

You have the ability to modify the settings.

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 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, 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.

Multi-Level Drill Down

If more than one value is added to the Columns field, an alert message will be displayed. 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 a stacked area chart in a series.

Hidden Column

Hidden columns are useful in cases where we do not want the fields to participate in the visualization, but rather 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. In Date fields, we will have all available types except sorting, relative date filter, settings, and filters.

Linking

The primary use case for hidden columns is linking. When configuring hidden columns, we can observe that 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 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 affect the visualization, we can configure the matches in the hidden columns and include them in 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 the Custom button that is highlighted in the filter configuration dialog image below. It will display a list of all the fields that are configured in the widget. Keep the field that is configured in the hidden column and remove the other fields, then click 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 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 info icon in the Hidden Column section.

The chart below displays the goals and attempts on target 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 individual columns are split based on the hidden column field. This affects the chart visualization, as can be seen in the image below.

How to format stacked area chart?

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

To configure data into a stacked area chart, follow these steps:

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

2. Configure the data for the stacked area chart.

3. Direct your attention to the stacked area chart and click on the widget settings.

By default, the chart axis shows positive values at the top and negative values at the bottom. However, there are times when we need to invert the axis and display the negative values at the top and positive values at the bottom. For example, when we bind temperature data to the chart and want to display the negative values at the top, we can utilize this feature.

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

Axis Range Settings

This allows you to manually set the Minimum, Maximum, and Interval values of primary value axis through the Axis Range Settings dialog.

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

Parameter Support in Axis range:

This 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 dashboard parameter values. 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 numeric format as shown below.

Click on the axis range settings dialog and input @ in any textbox (minimum, maximum, and interval). Choose the parameter value (Only number type parameter values are allowed).

The parameter value is now reflected in the chart axis.

Range Parameter Value:

If you want to set the same ranges in multiple cases, create the range type parameter value. This parameter type has 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. First textbox value is stored in the start parameter, and the second textbox value is stored in the end parameter. Select the parameter value (Number type parameter values only allowed).

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

Data Source Field Based Parameter Value:

1. Create a parameter in the data source type, where you can choose any field. The value of the parameter will be based on the selected field value.

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

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

Use Default Palette

This Option allows you to apply 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 for chart series based on data. If you want to apply a specific color to specific data(i.e. Violet color for 2021, Sky Blue color for 2022, and green for 2020), you can use Data based color mapping. By default, the Color Mapping Type will be Data.

Index

It allows you to apply color for chart series based on Index. Such that the colors are maintained based on index even if data is changed. It shows only 15 different colors. After that, the color will be repeated from above colors.

For example, If you are displaying the countries based on the increasing order of the case count, then the index-based color mapping will be useful to set the colors based on the rank. Say red color to the top, then the red color will be maintained for the country having the largest case count.

Note: We prefer to use Index based color customization only for minimum data(upto 15 series).

Font settings

This section allows you to customize the font size of chart elements.

Auto font Size and font size
