Why is your chart width zero?

In our application(datart), we set default container width to zero, and wait dataset back and debounce calculate the frame container width and height. For sure, we could set default is 1px or more, then the chart will reset width to 600px for example, the graph will be twinking.
For sure when the width set to 0, is it not make sense to draw any graph for ECharts, but sometime it is useful to init echart instance and resource, so it is much better to avoid Exception I think. In other word, it is seemed not friendly error message when width to zero.

Using isFinte(rate) may be better

Sure, is it better for if (isFinite(rate) && rate > 1) ?

Looks good.

We didn't suggest initializing a chart with zero width. But I think it's also not expected to have an expection that will break the following setOption or resize.
