Hi
There is issue with my csv export for gauge chart.
when I export a chart as a csv it downloades the chart as first column with value 0.
Is there any way to avoid that and get only one column for gauge type charts.
currently my csv contains data like below after downloading :
e.g. Micromarket | total stock (%)
0 | 18.41
But i want data should be like this after download :
e.g. total stock (%)
18.41
Please refer my below JS fiddle link for reference.
