Specify the number of historical data points you want displayed in the “Buffer Size” property and add “this.Redraw” to any one of your trace query commands. NOTE: This will result in MC4 having to redraw the plot field every update cycle, so you will see your CPU useage increase when you make this change. Another possibility is to have an object send the “Clear” command to the XY PLOT at a specified interval.
