Exporting Data in CSV 

You can easily export data associated with any chart using the exportCSV method associated with the <charts> tag (see Chart Tags).

Assuming that you want to export data associated with the line chart template with a row header containing the x-axis labels and a column header containing the legend labels of the two curves. Add the following code to the Templates field of the Flexform.

<template id="1">
    EXT:sav_charts/Resources/Private/Templates/ChartsExamples/LineChart.xml
</template>

<data id="data">
  <item key="0" value="data#dataSet0" />
  <item key="1" value="data#dataSet1" />    
</data>

<data id="exportRowHeader">
  <item key="0" value="marker#labelSet0" />
  <item key="1" value="marker#labelSet1" />
</data>
                
<exportCSV reference="lineChart#1" rowHeader="data#exportRowHeader" columnHeader="data#labels" data="data#data" />
Copied! 
<c:template id="1">
    EXT:sav_charts/Resources/Private/Templates/ChartsExamples/FluidParser/LineChart.fluid
</c:template>

<c:data id="data">
  <c:item key="0" value="{data__dataSet0}" />
  <c:item key="1" value="{data__dataSet1}" />   
</c:data>

<c:data id="exportRowHeader">
  <c:item key="0" value="{marker__labelSet0}" />
  <c:item key="1" value="{marker__labelSet1}" />
</c:data>

<c:exportCSV fileName="LineChart_1.csv" rowHeader="{data__exportRowHeader}" columnHeader="{data__labels}" data="{data__data}" />
Copied!

The CSV file is saved in typo3temp/sav_charts.

With the XML parser, the file name is img_ContentId_ChartNumber, where ContentId is the UID of the content element and ChartNumber is the ID of the chart, starting from 0. In the front-end you should see an icon to open the file.

With the Fluid parser, the file name is provided in the argument fileName.
