Column Chart

A column chart allows you to compare values for a set of unordered items across categories using vertical bars that are arranged horizontally.

How to configure the table data to column chart

A Column chart requires at least one value element and one column element in order to be displayed. The measure column or expression column that you want to analyze can be placed in the values block. The dimension column that you want to use to categorize the measure column can be placed in the columns block. If you want to categorize based on a series column, then the corresponding dimension column can also be placed in the rows block. These blocks are combined in the Data pane.

The following steps explains the data configuration of column chart:

1. Drag and drop the icon for the column chart control from the toolbox into the design panel. You can locate the control in the toolbox by searching for it.

2. Please resize the widget as necessary.

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

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

5. In the connection type panel, click on any one of the listed connection type buttons. (Here, the Microsoft Excel connection type is selected for demonstration.)

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

7. Please drag and drop your preferred table or view from the left pane in the data design view, and then click the Save button.

8. Please click the Properties icon in the configuration panel.

9. The properties panel of the widget will be displayed as shown in the screenshot below.

10. Now, switch to the ASSIGN DATA tab.

11. The ASSIGN DATA tab will be opened with the available columns from the connected data source.

Adding fields to Value(s)

To bind a column, drag and drop the element from the sections to the values section.

IMPORTANT:

• The field added in this section will act as a measure value.
• This section is mandatory for the widget visualization, and an unlimited number of fields can be configured in it.

Settings menu options

You can filter and format the data displayed in the widget from the options in the settings menu. To open the settings menu, click the settings icon.

The following screenshots show the various options in the settings menu, which are based on the type of field configured in the type section.

Renaming fields

The field names that have been configured can be edited by utilizing the Rename option which is available in the settings menu.

Changing the aggregation type

You can change the aggregation type of the measure section from the settings menu, as shown in the following screenshot. Please refer to this section for more details.

Filtering data

You can change the values by selecting the Filter option and using Filters. For more details, refer to the Measure filter and dimension filter.

Measure formatting

You can format the elements by selecting the Format option. For more details, please refer to the measure format.

Removing the fields

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

Adding fields to Column(s)

Please drag and drop the elements from the sections into the columns.

IMPORTANT:

• The field added in this section will function as a dimension value.
• It is an optional section, and adding more than one value will enable drill down.

Settings

You are able to change 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

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

Filtering data

You can apply a filter by selecting the Filter(s) option in the settings. For more details, refer to the filter.

The chart will be displayed in this manner.

Similarly, you can add the Measures and Expression Columns into the column field.

Drill down

When the second value is added to the Columns section, the alert message will be displayed.

Click Yes to enable the option. If you click No, a single value will be added to the Columns section.

Figure: Chart with a drilled view of the selected region.

Adding fields to Row

Please drag and drop the elements from the sections to the Row.

Hidden Column

Hidden columns are useful in cases where we do not want the fields to participate in the visualization. Instead, we only want them 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: Rename. 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. When 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 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.

Please click the Custom button, which is highlighted in the filter configuration dialog image below. This will display a list of all the fields configured in the widget. Please keep the field that is configured in the hidden column and remove the other fields. Finally, 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 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 chart visualization, as shown in the image below.

Adding tooltip fields

You can configure the tooltip section to display additional information in the widget’s tooltip without impacting the visualization. Please refer to this section for further details on how to configure the tooltip fields.

Color Mapping Type

By utilizing the Color Mapping type, you have the ability to apply colors to the series, whether it be based on data or index.

Data

It allows you to apply color to chart series based on data. If you want to apply a specific color to specific data, you can use data-based color mapping. By default, the color mapping type will be Data.

Index

It allows you to apply color to chart series based on the Index, ensuring that the colors remain consistent even if the data is changed. A maximum of 15 different colors can be displayed, after which the colors will repeat from the ones used above.

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

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

Color

You can choose the color for the record using the color picker nearby.
