Exporting Charts
FusionCharts Suite XT uses JavaScript to render charts in the browser using SVG and VML. A prominent feature of the suite is the ability to export the rendered charts in JPG, PNG, SVG, PDF formats and export chart data as well.
In this section we will discuss how to:
Export Charts as Image and PDF#
A server-side helper library enables export by conveting the SVG to the required format. You can also export VML as it is converted to SVG internally before exporting. During the export process, the data to be exported is first sent to the FusionCharts servers to be processed, finally generating the output in the required format.
When charts are exported on the client side, the entire exporting process is carried out using the user’s browser. The chart’s SVG is converted into the selected export format and download using the HTML5 download
attribute.
You must have an active internet connection for this feature to work.
To enable chart exporting, the chart
level attribute exportEnabled
is set to 1. The (menu) button is then visible on the top-right corner of the chart. Click/hover over this button to see the dropdown menu with export options, as shown in the image below:
From the menu rendered, select the required format. The chart is downloaded to your machine in the selected format.
A column 2D chart with export enabled is shown below. Click the (menu) button and select the required export format.
{
"chart": {
"caption": "Countries With Most Oil Reserves [2017-18]",
"subCaption": "In MMbbl = One Million barrels",
"xAxisName": "Country",
"yAxisName": "Reserves (MMbbl)",
"numberSuffix": "K",
"exportEnabled": "1",
"theme": "fusion"
},
"data": [
{
"label": "Venezuela",
"value": "290"
},
{
"label": "Saudi",
"value": "260"
},
{
"label": "Canada",
"value": "180"
},
{
"label": "Iran",
"value": "140"
},
{
"label": "Russia",
"value": "115"
},
{
"label": "UAE",
"value": "100"
},
{
"label": "US",
"value": "30"
},
{
"label": "China",
"value": "30"
}
]
}
The full code of the above sample is given below:
// Include the core fusioncharts file from core -
import FusionCharts from "fusioncharts/core";
// Include the chart from viz folder
// E.g. - import ChartType from fusioncharts/viz/[ChartType]
import Column2D from "fusioncharts/viz/column2d";
// Include the fusion theme
import FusionTheme from "fusioncharts/themes/es/fusioncharts.theme.fusion";
// Add the chart and theme as dependency
// E.g. FusionCharts.addDep(ChartType)
FusionCharts.addDep(Column2D);
FusionCharts.addDep(FusionTheme);
// Create an Instance with chart options
var chartInstance = new FusionCharts({
type: "Column2D",
width: "700", // Width of the chart
height: "400", // Height of the chart
dataFormat: "json", // Data type
renderAt: "chart-container", //container where the chart will render
dataSource: {
// Chart Configuration
chart: {
caption: "Countries With Most Oil Reserves [2017-18]",
subCaption: "In MMbbl = One Million barrels",
xAxisName: "Country",
yAxisName: "Reserves (MMbbl)",
numberSuffix: "K",
exportEnabled: "1",
theme: "fusion"
},
// Chart Data
data: [
{
label: "Venezuela",
value: "290"
},
{
label: "Saudi",
value: "260"
},
{
label: "Canada",
value: "180"
},
{
label: "Iran",
value: "140"
},
{
label: "Russia",
value: "115"
},
{
label: "UAE",
value: "100"
},
{
label: "US",
value: "30"
},
{
label: "China",
value: "30"
}
]
}
});
// Render
chartInstance.render();
The above chart has been rendered using the following steps:
Include the necessary library files like
fusioncharts
library, fusion theme file, etc.Store the chart configurations in a JSON object. In this JSON object:
- Set the chart type as
column2d
. Find the complete list of chart types with their respective alias here. - Set the width and height (in pixels).
- Set the
dataFormat
as JSON. - Embed the json data as the value of the
dataSource
. - Set the value of
exportEnabled
attribute to1
, which enables the export feature of the chart.
- Set the chart type as
Add a container (instance) for the chart.
Modes of Export#
FusionCharts Suite XT supports the following three modes of export:
- Server-side export
- Client-side export
- Auto-export
By default, charts are exported using the auto-export feature.
The exportMode
attribute is used to switch between the different modes of export.
Starting from version v3.12.1, the
exportMode
attribute replaces theexportAtClientSide
attribute.
To process the export data on your own server, configure one of the export handlers by following the Setup Private Export Server guide.
Export Chart Data in XLSX Format#
FusionCharts lets you export the rendered charts in JPG, PNG, SVG, and PDF formats. Starting v3.13.5, FusionCharts Suite XT introduces exporting chart data in the XLSX format (as an Excel spreadsheet).
To enable chart exporting, set the chart level attribute exportEnabled
to 1. The (menu) button is then visible on the top-right corner of the chart. Click/hover over the button to see a dropdown menu with the export options, as shown in the image below:
To export chart data, select the Export as XLSX option. The XLSX file with the chart data gets downloaded to your machine.
A column 2D chart with export enabled is shown below. Click the (menu) button and select the Export as XLSX option to export the chart data.

To export a chart in the XLSX format using server-side exporting, it is mandatory that the exporting server has the latest code, available in the FusionCharts package. Alternatively, you can also use the FusionCharts export link,
export.api3.fusioncharts.com
. For client-side exporting, the exporting chart data feature is supported only by modern browsers with canvas support (except Safari and IE9). You can still export your charts, without including the configurable data.
To process the export data on your own server, configure one of the export handlers by following the Setup Private Export Server guide.
