1. Is this request related to a challenge you're experiencing? Tell me about your story.

I want to generate a bar chart in Dify. I choose to use the langgenius/echarts tool, but now I want one horizontal coordinate point to correspond to multiple data, that is, to display multiple bar charts in one graph, instead of only displaying a single one. I wonder if this can be achieved? If it can, how should the echarts parameters be passed? If not, are there any other good methods

The best method is to use code conversion to generate Python or JS code, 【echarts_code = f"echarts\n{json.dumps(echarts_config, ensure_ascii=False)}\n"
return {"current_echarts_code": echarts_code}】
