If you just need to display two multicharts, you can create two MultiChart objects and assign them to two chart viewers on the same page. Many examples that come with ChartDirector include multiple charts on the same page. For example, the following example display 6 bar charts on the same page:
For your case, you can use MultiChart objects instead of XYChart objects for the chart viewers.
If you also need the multicharts to update in realtime, the exact code depends on your programming language/framework. Would you mind to clarify which programming language/framework you are using (Eg. C#/ASP.NET, PHP ...)?
