<h2>Graph2d | Label Example</h2>
|
||||||
|
<div style="width:700px; font-size:14px; text-align: justify;">
|
||||||
|
This example shows the how to add a label to each point in Graph2d. Each item can have a label object which contains the content and CSS class.In addition, xOffset and yOffset will adjust the location of the label relative to the point being labelled.
