We do not have a chart field type, but if you chart is just an image file, you can include it with an Image field type from Basic Fields.
Another example is a chart from Google Spreadsheet embedded to the form. It is possible to publish the chart from Google Spreadsheet to add its embed code to your form. The embed code should be added with a Text HTML field type.
If you need any further assistance, please let us know.
