Hello @hsauod! I'm here to help you with any bugs, questions, or contributions you might have for the project. Let me know how I can assist you!

The Chart Tool in Dify version 0.6.11 only accepts strings for the "data" and "Categories" fields. The expected format for these fields is a semicolon-separated string of numbers for "data" and a semicolon-separated string of texts for "Categories" [1][2].

However, there have been updates in version 0.6.13 that address data type handling. Specifically, the code now includes a check to convert all data to integers if they are all digits, otherwise, it converts them to floats [3].

If you are experiencing issues with arrays, lists, or numbers not being accepted, ensure that you are using the correct string format as described. If the problem persists, consider updating to version 0.6.13, which includes improvements in data type handling.
