Change Shape Visual Elements Dynamically
The following example demonstrates how to find a particular element from the shape visual in the Diagram and dynamically change it.
This means to change the rectangle fill and stroke options on hover.
<div id="diagram"></div>
<script>
function createDiagram() {
$("#diagram").kendoDiagram({
mouseEnter: function (e) {
if (e.item instanceof kendo.dataviz.diagram.Shape) {
e.item.shapeVisual.children[0].redraw({
fill: "black",
stroke: {
width: 3,
color: "red"
}
});
}
},
mouseLeave: function (e) {
if (e.item instanceof kendo.dataviz.diagram.Shape) {
e.item.shapeVisual.children[0].redraw({
stroke: {
width: 0,
color: "none"
},
fill: e.item.dataItem.colorScheme,
});
}
},
dataSource: new kendo.data.HierarchicalDataSource({
data: data,
schema: {
model: {
children: "items"
}
}
}),
layout: {
type: "layered"
},
shapeDefaults: {

});
var diagram = $("#diagram").getKendoDiagram();
diagram.bringIntoView(diagram.shapes);
}
$(document).ready(createDiagram);
