In this example, you can see how to switch the Heatmap to canvas rendering mode.The rendering performance will be better in Canvas rendering mode, while loading large datasets. You can switch the rendering mode for Heatmap between SVG and Canvas using the renderingMode property. When the renderingMode property is set to Auto the rendering mode will be switched automatically based of the size of data source to improve the rendering performance. Tooltip is enabled in this example, to see the tooltip in action, hover a point or tap on a point in touch enabled devices. Injecting Module Heatmap component features are segregated into individual feature-wise modules. To use a tooltip, inject the Tooltip module using the Heatmap.Inject(Tooltip) method, and use a legend by injecting the Legend module using the Heatmap.Inject(Legend) method.
