   True - the axes will flicker. And true - [appendData](https://echarts.apache.org/en/api.html#echartsInstance.appendData) is not officially supported for _line3D_.
   But one can somewhat remedy the problem.
          First - by not explicitly redraw the chart with ```setOption(option, true);``` - **true** means redraw/replace.
            Second - by setting **max** values to axes
            Third - by decreasing the frequency
            (Fourth - upgrade computer to faster one)
   Update [the example](https://echarts.apache.org/examples/en/editor.html?c=line3d-orthographic&gl=1) with following code
   ```
     xAxis3D: {    type: 'value', max:12  },
     yAxis3D: {    type: 'value', max:12  },
     zAxis3D: {    type: 'value', max:30  },
   
   setInterval(() => {
     option.series[0].data.push([Math.random()*11.3,Math.random()*10.3, Math.random()*15.3])
     myChart.setOption(option);  //, true);
   }, 800);
   ```
   and flicker will disappear when tested on Intel i5 processor.
