Combo Chart Widget (Themable)
Overview
The Combo Chart widget enables you to represent data series on the chart using multiple marker types, such as columns, lines, area, and points. You can overlay multiple sets of data using different types of visualization to compare the quantities of units across multiple data series. The Y-axis represents quantity and the X-axis represents the category. Displaying data using different chart visualization types makes it easier to read the different scales for the Y-axes.
The following are some the main configurations that are available for the Combo Chart.
• Visualize data series using lines, columns, areas, and points.
• Bind data from multiple sources.
• Configure the stacking order ZIndex of the data series.
• Apply state formatting to style the chart based on values.
• Group and stack data series.
Best Practices
• Keep data sampling enabled to improve the chart performance at run time. Disabling data sampling may cause slower performance when the chart displays thousands of data points from multiple series. You should only disable sampling when the chart data set is small. To control data sampling, use the SampleSize property. For more information, see Configuring Data Sampling for Charts.
Data Format
You must create an infotable with field definitions that represent the data structure for the chart. The infotable must include a field definition for the X and Y-axis values. You can add multiple data series by adding additional columns with field definitions for the data series values. Each infotable row represents a category on the X-axis and its corresponding Y-axis values. The following table lists the data format for the infotable:
X Axis | Y Axis Value | Y Axis Value N | |||
|---|---|---|---|---|---|
Field Definition | x:{name: 'x', baseType: 'STRING'} | value1: {name: 'value1', baseType: 'NUMBER'} | value2:{name:'value2',baseType:'NUMBER'} | ||
Use | Defines the X-axis values. The data must have a STRING, NUMBER, or a DATETIME base type. Each row is displayed as a category on the X-axis. The defined name for this column is the option that you should select for the XAaxisField widget property. | Defines the Y-axis value and the legend label for the category. | Defines the Y-axis value and the legend label for each additional data series. | ||
Base Type | STRING, NUMBER, or DATETIME
| NUMBER | NUMBER | ||
Row Example | x: 'Apple'—Where Apple is a category name to show on the X-axis | value1: 10—The Y-axis value for the category | value2: 30—The Y-axis value for data series N. |
The following image shows an example of returned data from an infotable with four field definitions for the y-axis:
