Steps to reproduce

{
  "inputs": {},
  "query": "随机生成一个柱状图"
}

"![](https://some-random-url.com/example-bar-chart.png)\n\n这是一个基于随机数据生成的柱状图，展示了不同类别（A, B, C, D, E）上的数值变化。从图表中可以看出，从A到E，数值逐渐增加，这可能代表产量、订单量或任何其他度量标准的增长趋势。\n\n如果你希望对特定的数据进行分析或需要进一步的帮助，请提供更具体的信息或数据集。"

The issue you're experiencing with the echarts tool not generating the expected chart and instead returning a non-functional link could be related to how Dify processes and returns links for generated charts. Dify uses the create_link_message interface to handle these links, and a link might be non-functional if the URL is incorrect, the server is down, or there are network issues. Additionally, Dify does not support deep links or custom protocol links, which could result in links being rendered as javascript:void(0) and not clickable ^[1][2].

To address this issue, you might want to check the following:

1. Ensure that the URL being generated is correct and accessible.
2. Verify that the server hosting the link is operational.
3. Check for any network issues that might be preventing access to the link.
4. Confirm that the link is properly formatted and not using unsupported protocols.

If these steps do not resolve the issue, it may be necessary to review the implementation code for any potential bugs or misconfigurations.

@junjiem Can you take a look at this?

[junjiem]

This is not echarts tool problem, it is a problem that the llm capability or prompt in the agent.

[junjiem]

After the agent invokes the tool and returns the result, the agent sends the result to the LLM again for generation. It is better to have a switch at the tool level whether to return the result directly, and the agent decides whether to generate it again according to this parameter.

chatflow should be used to output from the 'direct reply' node after invoking the echarts tool
If it is parallel, you need to reference echarts/text after line feed when replying directly
This is the result of my test, I hope it can help the people behind
