Hey Asif,
What type of data is in the shared variable? You should be able to just right-click the variable, change the Access Mode to "Read" and add an indicator to it. If the indicator is not automatically a plot, you can right-click the indicator on the front panel and replace it with a plot that you want. If you are having trouble, feel free to include a screenshot, which may help us better see what you are trying to do.
