I need to do custom marker on google maps.
How can I sort and rangesum on google maps extension based on expression (sort , rangesum, cumulation) to display custom marker for each lat/long.
When rangesum is applied, i will display green marker for rows (lat/long) with rangesum value less than 15
i will display red marker for rows (lat/long) with rangesum value more than 15 and less than 30.
Thank you in advance
