React Chart Markers
In Ignite UI for React, markers are visual elements that display the values of data points in the chart's plot area. Markers help your end-users immediately identify a data point's value even if the value falls between major or minor grid lines.
React Chart Marker Example
In the following example, the Line Chart is comparing the generation of renewable electricity for the countries Europe, China, and USA over the years of 2009 to 2019 with markers enabled by setting the
MarkerType property to "Circle."
The colors of the markers are also managed by setting the
markerOutlines properties in the sample below. The markers and
chartType is configurable in this sample by using the drop-downs as well.
React Chart Marker Templates
In addition to marker properties, you can implement your own marker by setting a function to the
MarkerTemplate property of a series rendered in the
IgrCategoryChart control as it is demonstrated in example below.
