Hello, 
  
I have a RealtimeStackedColumn chart, which I am just feeing random values to every second.  Every second when the chart updates, a new column is added (see picture).  What I would like instead is to have a fixed amount of columns (one for each day of the week) and then update the existing columns, depending on the data. 
  
The code in my DataSource (I am using C#) is: 
Response.Write ("&label=" + label+ "&value=" + randomValueCr1 + "|" 
+randomValueCr4 + "|" + randomValueCr5);
