Creating Multi-series Charts
FusionCharts Suite XT includes multi-series charts that allow to plot data for multiple datasets. For example, you can plot the revenue collected each month for the last two years using a multi-series chart. Multi-series charts allow to plot the highs and lows of multiple datasets while also comparing them.
The different types of multi-series charts available in the FusionCharts Suite XT are:
-
Multi-series Column 2D Chart
-
Multi-series Column 3D Chart
-
Multi-series Bar 2D Chart
-
Multi-series Bar 3D Chart
-
Multi-series Line 2D Chart
-
Multi-series Area 2D Chart
In this section, you will be shown a few examples of how multi-series charts look and how you can create a simple multi-series chart.
Creating a Multi-series Column 2D Chart
A simple multi-series column 2D chart looks like this:

Brief Explanation of the Data Structure
In the JSON data, the attributes and their corresponding values are written in the following key-value pair format:
Given below is a brief description of the data structure needed to render a multi-series chart:
| Attribute Name | Description |
|---|---|
|
It is used to specify the type of chart you want to render. For example, to render a column 2D chart, the value for this attribute will be |
|
It is used to specify the container object where the chart will be rendered. |
|
It is used to specify the width of the chart. |
|
It is used to specify the height of the chart. |
|
It is used to specify the type of data that will be passed to the chart object. This attribute takes two values: |
|
It specifies the source from where the data will be fetched, depending on the value passed to the |
|
It is used to specify the chart caption. This attribute belongs to the |
|
It is used to specify the chart sub-caption. This attribute belongs to the |
|
It is used to specify the name for the x-axis. |
|
It is used to specify the name for the y-axis. |
|
It is used to specify the character that will precede all numeric values on the chart, e.g. |
|
It is used to specify the theme for the chart. |
|
It is used to specify the label for a data item. The label is rendered on the x-axis. This attribute belongs to the |
|
It is used to specify the value for a data item. This attribute belongs to the |
|
It is used to specify a name for the dataset. This name is shown in the legend box rendered below the chart. This attribute belongs to the |
Note that the number of category objects defined should be equal to the number of data objects defined, that is, if you mention twelve categories (twelve months), the data for both years (2013 and 2014) should also contain twelve data objects (twelve rows of data). Else, the chart will display empty space at that position.
