HeatLandSeries creates a heat map in the
GeoMap control, it helps to assign a numeric value to a region (country, state, continent, ... depends on the map)
then based on the gradient a color will be assigned to each region, colors are interpolated lineally based on the data scale in the series.
This property defines the gradient colors, it is an array of
where the first element in the array is the the smallest or coldest and the last item in the array is the greatest or hottest,
any value between the chart limits will be interpolated lineally to create a new color, you can add as many colors as you need
to define the gradient.
When this property is not specified, then it is assigned automatically based on the theme of the library.
By default all the colors in the
HeatMap property are separated equidistantly, you can define the distance
between each color using the
ColorStops property, it is an array of double, every item in the array must
go from 0 to 1, where 0 is the "coldest" and 1 the "hottest", notice in the following sample how the
black to blue gradient is only used in the last 10 percent of the gradient, while the yellow to black is
used in the remaining 90% of the gradient.
For simplicity the image above shows the cartesian heat series, just to explain the property better.
