Scene: echarts There are two graphics rendering, canvas rendering and rendering svg, are used in what kind of scene
Measures: Canvas graphic element is more suitable for rendering a very large number (which is typically caused by large volumes of data) graph (e.g., thermodynamic diagram, the geographic coordinate system, or on a large scale, or scatter plot line parallel to the coordinate system, etc.), but also conducive achieve certain visual effects; in many scenes, SVG has important advantages: lower (this is especially important for mobile end) its memory footprint, rendering performance is slightly higher, and when the user is not using the browser's built-in zoom function blurry.
At initialization chart instance, select parameters passed renderer type, as follows
// Use Canvas Renderer (default) var Chart = echarts.init (containerDom, null , the renderer {: 'Canvas' }); // equivalent to: var Chart = echarts.init (containerDom); // Use rendering SVG is var Chart = echarts.init (containerDom, null , the renderer {: 'SVG'});
