Color Mapping
28 Jun 20171 minute to read
Color mapping is used to indicate values as colors instead of numerical values. For example, if a HeatMap represents a data from 0 to 100. ColorMapping
is used to specify a color for lower value and higher value. For any value between two values, a medium color will be automatically be chosen.
In color mapping, when white color is set to value 0 and red color is set for value 30, as shown below.
<div ng-controller="heatmapCtrl">
<ej-heatmap id="HeatMap" e-width="100%" e-height="300px">
<div>
<e-colormappingcollection>
<div e-colormapping e-value="0" e-color="#8ec8f8"></div>
<div e-colormapping e-value="100" e-color="#0d47a1"></div>
</e-colormappingcollection>
</div>
</ej-heatmap>
</div>
syncApp.controller('heatmapCtrl', function ($scope) {
});
Resultant HeatMap will be as shown below.
