Wyn Enterprise: Bubble Chart

A Bubble Chart is used for graphical representation of multi-dimensional data. It displays an additional data value at each point by changing the size of the bubble.

Format Data Attributes

To format the data attributes and control the display of data, you can perform a variety of operations such as renaming, modifying data format and display unit, creating a hierarchy field, applying an aggregation method, etc.

For more information about these operations, see Data Attributes.

In the following chart scenario, the data attribute is renamed from 'Sum(Payout)' to 'Insurance Payout'.

Analyze Data

Wyn Dashboards scenarios support rich data analysis and exploration capabilities that can help analyze massive amounts of information and make data-driven decisions. For example, adding filters to the scenarios, sorting data, adding reference lines, trend lines, etc. Note that you can apply all these operations using the Action Bar corresponding to each scenario in the designer.

For more information, see Data Analysis and Interactivity in Dashboards.

The following image shows a reference line at an average value on the Y-axis.

Customize Appearance

You can customize the default chart appearance by setting properties in the Inspector tab of the scenario such as adding a border, modifying data labels, setting chart style, renaming chart title, setting corner radius, etc.

  1. Show Grid Lines
    To display horizontal grid lines in a chart scenario, you can set the Show Grid Lines property of the value axis to 'True'. By default, this property is set to 'False'. You can also specify the grid line color by choosing a suitable color from the color palette.

  3. Format Axis Titles
    You can show or hide axis titles for a chart by using the Show Title property for the Legend, Value axis, and Category axis. When you set Show Title property to 'True', the axis titles are enabled. Wyn Dashboards set data attributes' names as the axis titles. You can provide a custom name to the axis title by renaming the attributes in the data binding area. For more information on renaming data attributes, see the topic on Rename an Attribute.
