Questions about JavaFX's webview call echarts dot line does not correspond

I'm going to need to show the chart on JavaFX recently, so I'm planning on using JavaFX's WebView to invoke Echarts.

Because before also used Echarts, and in the browser call is also very normal, but put on webview up will appear dot line does not correspond to the situation

It feels like the scale of the line is not correct, and then the Echarts API turns out that 4.x has a new feature, which can be configured to render as canvas or SVG, and the default is canvas.

It then changes to SVG, initializing the code:

var null, {renderer: ' svg '});

Run over and solve the problem.
