I have created a line chart with several columns from a google sheets table. One of the lines is wind speed. In the table there is also a column that contains wind direction. One can show the points of the line with a triangle which can be rotate. The issue is that the table on which the charts is based updates every 30 minutes so hardcoding the direction is not possible. How do I feed the direction from the table column dynamically into the point option? pointShape: { type: 'triangle', rotation: 180 } Thanks !
