Chart - how to get column value from Container and pass it to title

Migrateduser

<p>Hello,</p>
<p> </p>
<p>I have data grouped by STATION. For each group a chart is created with data "Inherit data from container".</p>
<p> </p>
<p>I need to change the title for the chart and show the STATION. I know how to change the title</p>
<p> <span style="font-family:'courier new', courier, monospace;">function beforeGeneration(chart, icsc) {<br>
    chart.getTitle().getLabel().getCaption().setValue("....");<br>
 }</span></p>
<p>but I don't know how to pass value from column STATION.</p>
<p> </p>
<p>Thank you very much in advance,</p>
<p>Lucy</p>
