Hi Zhengwu,

You’ve missed two chart attributes in the component description: titleField and valueField (see the screenshot on page 103). So, your pieChart should look like this:


        <chart:pieChart id="ratingChart"
                        datasource="ratingDs"
                        titleField="mechanic"
                        valueField="count"
                        height="200px"
                        width="100%">
            <chart:legend position="LEFT"/>
        </chart:pieChart>

It works. Thank you very much.
