MatLab + Vicon SDK plot the values

Hi guys, first time and mu knowledge in matlab is small, but i will try to expose my question as clear as possible.

I want to plot my data that comes out from the vicon system in real time, the current code i have i can achive this but from the 21 markers the plot values erase the previous values and I'm just interested in the 4 markers.

The Output_GetMarkerGlobalTranslation.Translation 1 is my X; 2 is my Y and 3 is my Z.

I just want the Y from marker 2,3 and 5,6. But i want to plot the 4 markers(y values only at the same time.

I attached the entire code if it helps.

                     
                     
    % Count the number of markers
    MarkerCount = MyClient.GetMarkerCount( SubjectName ).MarkerCount;
    fprintf( '    Markers (%d):\n', MarkerCount );
    for MarkerIndex = 0:typecast( MarkerCount, 'int32' )-1
      % Get the marker name
      MarkerName = MyClient.GetMarkerName( SubjectName, typecast( MarkerIndex,'uint32') ).MarkerName;

      % Get the marker parent
      MarkerParentName = MyClient.GetMarkerParentName( SubjectName, MarkerName ).SegmentName;

      % Get the global marker translation
      Output_GetMarkerGlobalTranslation = MyClient.GetMarkerGlobalTranslation( SubjectName, MarkerName );

      fprintf( '      Marker #%d: %s (%g, %g, %g) %s\n',                     ...
                         MarkerIndex,                                    ...
                         char( MarkerName ),                                         ...
                         Output_GetMarkerGlobalTranslation.Translation( 1 ), ...
                         Output_GetMarkerGlobalTranslation.Translation( 2 ), ...
                         Output_GetMarkerGlobalTranslation.Translation( 3 ));
      %Plot
      bar([mean(Output_GetMarkerGlobalTranslation.Translation( 1 )) mean(Output_GetMarkerGlobalTranslation.Translation( 2 )) mean(Output_GetMarkerGlobalTranslation.Translation( 3 ))])
      xlabel( 'MarkerName' );
