Fixed incorrect recognition of data input in chart

[engery]

Description

The original logic, when processing data such as 12, 23, 34; 230,340,540, the original code will first follow the ";" After splitting, mistakenly taking 12, 23, and 34 as one number for judgment; I made the modifications and will start with ';' After splitting, first perform ',' and then perform int and float judgments to avoid this problem!

How Has This Been Tested?

I ran locally and tested different situations, such as when the data is one group or multiple groups.

• TODO

Sorry that I still fail to understand the key point of the supposed fixes.
Any comparison in parsing outputs for the without or with this fixes?

I guess you are trying to enable the drawing of multiple lines on the same chart, it makes sense, but you should update the description of data as LLM should be informed that how to generate the data you want, but also, human_description needs to be optimized, otherwise, developers are confused
