    I have a dataset of values that I want to have represented in Pie charts, and I would like it if the RadHTMLChart could generate separate pie charts, delimited by the content of one of the data columns.

    Is there any way I can do this with a single RadHTMLChart, or do I need to create separate charts, and manually break the datasets apart, feeding the broken datasets to separate charts?

    I have attached examples of the dataset I'm working with, and the sort of output I'm hoping to achieve with the RadHTMLChart.  In the attached file, column QuestCode delimits the series, and AnswerLabel/Cnt identify the data elements for each pie chart.

    Thank you!

    Hi Mike,

    The HtmlChart is designed to render only one chart instance as per the passed data values. You can, though, implement your own cycle iterating the column names of the database and assign them to the corresponding data fields of dynamically created charts:
