i having a problem writing a data label and also selecting type of value as percentage
In the Web GUI use case, while using the Pie Chart Maker, you only need to enter the required values in the input fields on the webpage. Once the values are provided, the pie chart is automatically generated on the web page.
For data labels and percentage values, ensure that the label field and value field are correctly populated. The chart tool will automatically calculate and display the percentage based on the values entered.
