How can I plot the messages in two different graphs

C#

Hi,

I am using the following code to plot the graph for the response times of messages

The code is working fine. But I want to plot the messages passing from bus 1 to bus 2 in half space of graph and messages passing from bus 1 to bus 3 in another half space of the graph with same scale
But the following code plots all the messages in same graph
Can anyone have suggestion about this???

if (numofBuses == "3")
            {

                foreach (GatewayMessageDetails GWmsgDetails in GWmsgDetailsList)
                {
                    if (GWmsgDetails.LatencyBusOnetoBusTwo == 0)
                    {

                        int MsgNo = (GWmsgDetailsList.IndexOf(GWmsgDetails) + 1);

                        pltOutput.Series[Constants.LEGEND_CYCLETIME].Points.AddXY(MsgNo, GWmsgDetails.TotalDeadLineTimeOfBusOnetoBusTwo);
                        pltOutput.Series[Constants.LEGEND_RT_SUCCESS].Points.AddXY(MsgNo, GWmsgDetails.ResponseTimeBusOnetoBusTwo);
                        pltOutput.Series[Constants.LEGEND_LATENCY].Points.AddXY(MsgNo, GWmsgDetails.LatencyBusOnetoBusTwo);

                        
                     
                    }

                   
                    if (GWmsgDetails.LatencyBusOnetoBusThree == 0)
                    {
                   

                        int MsgNo = (GWmsgDetailsList.IndexOf(GWmsgDetails) + 1);

                        pltOutput.Series[Constants.LEGEND_CYCLETIME].Points.AddXY(MsgNo, GWmsgDetails.TotalDeadLineTimeOfBusOnetoBusThree);
                        pltOutput.Series[Constants.LEGEND_RT_SUCCESS].Points.AddXY(MsgNo, GWmsgDetails.ResponseTimeBusOnetoBusThree);
                        pltOutput.Series[Constants.LEGEND_LATENCY].Points.AddXY(MsgNo, GWmsgDetails.LatencyBusOnetoBusThree);

                        // Set Plot Type for each series
                        pltOutput.Series[Constants.LEGEND_CYCLETIME].ChartType = SeriesChartType.Point;
                        pltOutput.Series[Constants.LEGEND_LATENCY].ChartType = SeriesChartType.Point;
                        pltOutput.Series[Constants.LEGEND_RT_SUCCESS].ChartType = SeriesChartType.Point;


                      

                   

                }
            }
