折れ線グラフのデータ系列を行（レコード）単位にしたい

[NISHIKIDA]

こんにちは。

折れ線グラフについて
データ系列を列（カラム）単位ではなく行（レコード）単位で表示したいのですが
何かいい方法はないでしょうか？

やはりレコードセット自体を変更するしかないのですかね？

このソースだと列(カラム)単位になってしまう......

Code:

{curl 8.0 applet}
{import * from CURL.GUI.CHARTS}
{let RS:RecordSet =
    {RecordSet
        {RecordFields
            {RecordField "BASE", domain = String},
            {RecordField "Month_4", domain = int},
            {RecordField "Month_5", domain = int},
            {RecordField "Month_6", domain = int}
        },
        || hidden = 0
        {RecordData BASE = "A", Month_4 = 120, Month_5 = 150, Month_6 = 200},
        {RecordData BASE = "B", Month_4 = 100, Month_5 = 130, Month_6 = 115},
        {RecordData BASE = "C", Month_4 = 90, Month_5 = 70, Month_6 = 80},
        {RecordData BASE = "D", Month_4 = 130, Month_5 = 170, Month_6 = 150},
        {RecordData BASE = "E", Month_4 = 500, Month_5 = 450, Month_6 = 500}

        
    }
}       

{def rg = {RecordGrid
              record-source = RS,
              height = 130,
              width = 450,
              {RecordGridColumn "BASE"},
              {RecordGridColumn "Month_4"},
              {RecordGridColumn "Month_5"},
              {RecordGridColumn "Month_6"}
          }
}
{let chart:LayeredChart =
    {LayeredChart
        width = 15cm,
        height = 6cm,
        {LineLayer
            {ChartDataSeries RS, "Month_4"},
            {ChartDataSeries RS, "Month_5"},
            {ChartDataSeries RS, "Month_6"}
        }
    }
}

{value {VBox chart,rg}}
