hello every one,i have a problem that how can i shift signal level up and down using cursor in labview..plz helpp...

i have to shift level of signall..

Not sure what the subject line "rt" refers to. We will need more information to begin to help. Are you trying to change an actual signal output level, and if the answer is yes, how is the signal generated, what hardware do you have to control it? Please describe what you are trying to do with more detail.

Thanks for u r attention sir,,  i am try to prepare basic usb oscilloscope and preparing front panel with the help of labview.so as like standard company digital oscilloscope front panel i want to do vertical and horizontal positon control (The vertical position control allows you to move the waveform
up and down exactly where you want it on the screen.) of signal.

I presume that you mean you are using some USB DAQ device to capture the data and display it on the front panel. To then move that signal up and down is fairly easy, have a control that is "added" to the amplitude portion of your signal before it is displayed, it will provide an offset that will move the vertical access up and down (if autoscale for the X axis is not set on). Moving it horizontally may be a bit more problematic, I'll have to ponder it for a bit.

thank you sir for reply, i did this process of shifting of signal through offset for incoming signal..sir is there any possibilitie to do by changing the property of my graph only  or this will done through only that above process that u told me.

Actually, changing the graph properties is a good idea, I think my answer yesterday was given during a "senior" moment, was think more actual physical oscilloscope than LabVIEW. On the diagram side, right click on the icon for the graph, select "Create" and then "Property Node", in that pull down will be all of the accessable properties of that indicator.
