We have a Map with colour gradient driven by (response) values from an external .CSV where values can be positive or negative. We want the values say of -2 (eg for country1) and +2 (eg for country2) to show the same colour depth on the map but the default seems to treat the +2 as darker than -2
So wondered if HighCharts/Maps can accommodate the following:
- apply same colour depth to +2 as -2 values but maintain the unique sign of the value on Map mouseover for country 1 and 2
- (optionally) apply a different colour to +ve and -ve values respectively
Appreciate any pointers and/or demos or intro jsfiddles to kick us off
