Picture this: You are making a sales dashboard to be presented to the upper management of the company. During the presentation, your CFO asks you to pick out the raw data from a particular chart. At that moment, you cannot go back to the underlying database and give him the exact figures, can you? Nor can you afford to waste screen estate on dashboards by displaying tables right below the charts. So what now? Bring in FusionCharts v3.1’s option to export the data from your chart in CSV with a single click in the context menu — and your problems are solved.
So let’s say this is one of the charts you have in your sales dashboard:
When you export the data from this chart to CSV, this is how the result will come out:
Wouldn’t your CFO be happy when the data he requested comes out neatly formatted like that in a single click?
In case of a multi-series chart, the CSV data will have more columns – one for each series with the series name being the column header.

How to export chart data?
The chart data can be exported to CSV in two ways:
- Using the right-click menu of the chart, which copies the generated CSV data to clipboard.
Let’s take a look at both of them so that you can decide which one to take back home with you.
Exporting data from right-click menu
If you want to enable exporting of data using the right-click menu for your end user, it is as simple as this:
Copying chart data to clipboard in CSV using right-click menu
Now that the data has been copied to the clipboard, you can just open your favorite text editor and paste it.
To enable the Copy data to clipboard option in the right-click menu, you just need to set the
showExportDataMenuItem attribute of the <chart> element as 1.

If we did the above and put the data in an alert box as soon as the chart was loaded, this is what our output would look like:
Yes, it is more like a “Hello World” example but then you get the point, don’t you?

Don’t like the CSV output?
If you don’t like comma as the data separator and double-quotes as the data qualifier in your CSV output, you can customize them to your liking. This is done using the
exportDataQualifier attributes respectively.
If you want your CSV output to look a little cryptic for some purpose, here is something you can do:
The CSV output would now look like this:

Formatted CSV Output
FusionCharts smartly formats all the numbers in your chart using the number suffix/prefix as defined by you and using K(Thousands) and M(Millions) for large numbers. If you wish to export the chart data with all the number formatting in place rather than the raw numbers themselves, set the
exportDataFormattedVal attribute of the <chart> element to ‘1’ – it is turned off by default.
Once you have done that, the formatted CSV output would look as under:
That’s all about exporting data as CSV using FusionCharts. As always, we covered the feature here for FusionCharts specifically but it applies equally well to the other products in the FusionCharts Suite – FusionMaps, FusionWidgets and PowerCharts as well.
