仪表板获取具有10个元素的数据数组作为chdata属性.每0.5秒阵列更新一次新项目.我可以看到,数据在数据集中正在变化,但图表没有显示.

Uncaught TypeError: Cannot read property 'skip' of undefined悬停时也会出现此错误.

<input type="file">具体来说， Go中如何连接这个函数呢？我知道有“syscall/js”包，但我没有找到任何文件读取的示例。

func parseCSVFile(filePath string) []LabelWithFeatures {
    fileContent, _ := ioutil.ReadFile(filePath)
    lines := bytes.Split(fileContent, newline)
    numRows := len(lines)

    labelsWithFeatures := make([]LabelWithFeatures, numRows-2)

    for i, line := range lines {
        // skip headers
        if i == 0 || i == numRows-1 {
            continue
        }
        labelsWithFeatures[i-1] = NewLabelWithFeatures(bytes.Split(line, comma))
    }
    return labelsWithFeatures
}
