Examples on the main Page don't work

[vikram-rawat]

Example with ctx arguements don't work. and I wanted to know how to directly get the data from SQL to a dataframe and serve it as an API. I read your blog too. but that too had exactly the same examples.

This is a great package. thanks for working so hard.

Can you give me a code sample of what you were trying to achieve?

I am currently trying to learn it so that I can recommend it to be used in an upcoming project. But the examples mentioned on the site are not working... this is what I wrote..

package main

import (
    "fmt"
    "context"
    "github.com/rocketlaunchr/dataframe-go"
)

func main() {

    s1 := dataframe.NewSeriesInt64("day", nil, 1, 2, 3, 4, 5, 6, 7, 8)
    s2 := dataframe.NewSeriesFloat64("sales", nil, 50.3, 23.4, 56.2, nil, nil, 84.2, 72, 89)
    df := dataframe.NewDataFrame(s1, s2)

    df.Append(nil, 9, 123.16)
    df.Append(nil, map[string]interface{}{
        "day":   10,
        "sales": nil,
    })

    df.Remove(0)

    df.UpdateRow(0, nil, map[string]interface{}{
        "day":   3,
        "sales": 45,
    })

    sks := []dataframe.SortKey{
            {Key: "sales", Desc: true},
            {Key: "day", Desc: true},
        }

    df.Sort(ctx, sks)

    fmt.Print(df.Table())
}

add ctx := context.Background() at the top
