How do I get all the data in for loop in map of map in go?

package main

type Stream struct {
	Labels  string
	Entries []Entry
}

type Entry struct {
	Timestamp time.Time
	Line      string
}

now I have created a map of chunks

chunks := make(map[string]*Stream)

I am sending one test data and trying to form my chunks here

for _, line := range Lines {
	fmt.Println(line.Logmsg) // if I do print here I am getting all the data here 
	chunks["label"] = &Stream{
		Labels: "label"
		Entries: []Entry{
			Timestamp: time.Now(),
			Line:      line.Logmsg
		},
	},
}

fmt.Println(chunks) 

I am seeing the last data in the for loop here.

I am not seeing all the data compared to first println, is there anything I am doing wrong here ?

All insertions in the map are under the same key "label", so in the end the map will only contains one element.

Either use a different label for each element or use a slice.

You are assigning the stream to the same map key "label" for all lines:

chunks["label"] = &Stream{...}

Therefore the last line will always overwrite the previously set value. That is why you always only see that last line.

In order for the chunks in the end containing all data, you need to use some kind of dynamic key in this map. Something like:

chunks[line.Label] = &Stream{...}

I don't know your data so I can't tell which property you could use from line.
