# Indicators | How to Plot ROC of multiple symbols on same chart

Suppose your task is to plot ROC - or any other indicator - of all the symbols from a DataSet in one single pane. For example, you have IBM, AAPL, INTC in a DataSet, and you would like to plot ROC for each one of them on top of each other.

With Wealth-Lab .NET, it's easily possible. Here's a short code snippet:

```
using System;
using System.Collections.Generic;
using System.Text;
using System.Drawing;
using WealthLab;
using WealthLab.Indicators;namespace WealthLab.Strategies
{
public class MyStrategy : WealthScript
{
Random r = new Random();

private Color RandomColor()
{
Color randomColor = Color.FromArgb(r.Next(255), r.Next(255), r.Next(255));
return randomColor;
}		protected override void Execute()
{
string clickedSym = Bars.Symbol;
List<DataSeries> rocList = new List<DataSeries>();

foreach( string ds in DataSetSymbols )
{
//if( ds != clickedSym )
DataSetSymbols[DataSetSymbols.IndexOf(ds)], true ).Close, 10 ) );
}			HideVolume();
ChartPane rocPane = CreatePane( 100, true, true );
foreach( DataSeries ds in rocList )
PlotSeries( rocPane, rocList[rocList.IndexOf(ds)], RandomColor(), LineStyle.Solid, 1 );
}
}
}
```

Highlights:

• You need to loop over the DataSet's symbols (see: DataSetSymbols)
• Add each symbol's ROC (or another indicator) to the List of DataSeries created before (see: rocList)
• Then, you loop by that List and plot each series
• Look up the helpful List.IndexOf method in MSDN
• RandomColor is self-descriptive
