Hi Tumanovalex,
Thank you for contacting National Instruments. From what you have described here I think you are looking to update the graph that you have within your secondary tab when the values of the sampling information changes. By using a loop to continually monitor these values, and an Event Structure that creates an additional case that is triggered with the change of these variable values, you should be able to achieve this behavior. This should allow for the graph to be recreated when the values are changed.
I hope this is the behavior that you are looking for. Please let me know if you need more information or clarification. Have a great day!
