how to hide and show the plots in waveform chart

[developer help]

Hello
How to hide and show the plots in waveform chart.
in my program i am selecting the more than 1 channels for monitor data
so when i click select & add the selected channels will be added & displayed in the list box, so that channels will be
monitoring the data received through CAN channel.
now i want is,
 if i select particular channel in the list box by mouse click that channel data should be added to display in the
waveform chart, if i select more than 1 channel that channels plot should be displayed, if i deselect, that channels
plot display should be deleted from the display.
how to do this, give me an idea to modify this program
i attached my VI with this.

thanks
