Dummy question.
I have a CSV file that contains three columns (fields)
<date>, <value>,<group>
2017-01-01, 10, g1
2017-01-02, 11, g1
2017-01-03, 12, g1
2017-01-01, 20, g2
2017-01-02, 21, g2
2017-01-03, 22, g2
How can I draw two linecharts with Y-axis is <value>
, x-axis is <date>
, with respect to two groups?
Thanks,
Try |chart limit=0 sum(value) by date group
