I don't know how to dynamically update the plot content

[wingofsky]

Can anyone provide a sample code that dynamically updates the plot content?

Here's my code, it won't work

package main

import (
	"cogentcore.org/core/core"
	"cogentcore.org/core/plot/plotcore"
	"fmt"
	"math/rand"
	"time"
)

func main() {
	b := core.NewBody()

	type Data struct {
		Time   float32
		Users  float32
		Profit float32
	}

	var datas []Data

	pe := plotcore.NewPlotEditor(b).SetSlice(datas)

	go func() {
		for {
			datas = append(datas, Data{
				Time:   float32(len(datas)),
				Users:  rand.Float32(),
				Profit: rand.Float32(),
			})
			fmt.Println(datas)
			//pe.Update()
			//pe.UpdatePlot()
			pe.GoUpdatePlot()
			time.Sleep(1 * time.Second)
		}
	}()
	b.RunMainWindow()
}

The underlying representation of a plot is a tensor.Table, and SetSlice just converts to that, so you need to call pe.SetSlice(datas) again in your inner loop to get it to update correctly. The performance of that should still be good.

Thank you very much!

As you said, it achieved the effect I wanted
