5, solutions of some problems:

(1)    Document is Empty.  

We already configuration the csv data and use it, csv file also have data, but error is document is Empty, this maybe did not configuring the language.

(2)    Cast problem. 

this mostly caused by field class config error, we can change the field class style from string to double, float and so on.

(3)    Unable to get value for CSV field.

This problem, we can check data config again, sometimes our first time configuration has no effect. Need to check again.

Now, click preview, we can see the stacked chart.
