fix bug #20265 issue

Fixed issues

20265 : datazoom.filterMode设为'empty'时line图在缩放至只剩一条数据时所有数据都依旧会渲然，未依照empty的规则进行筛选。

Details

Before: What was the problem?

when dataZomm.filterMode is “empty” or ‘none’， the line graph is scaled to only one category, it is not filtered correctly

After: How does it behave after the fixing?

The data is correctly filtered. And The bug is caused by calling the normalize method when calculating rendering values. When extra [1]==extra [0], it does not consider the possibility of NaN and returns 0.5 directly
