How to get certain attributes of a graph?

How to get particular attributes from a graph of two variables such as Max( Y variable) and the value of X variable at the maximum point of the Y variable.

You don't get data from a graph. You get the data from the source of the graph. Use Array Min/Max. This will return the max value and the index of it on the array. From the index you can get the x value.

What if I want both X and Y values? I have the max value which is the max Y value and I want the X value corresponding to the Y value

I already said what you need to do to get the max y value and its index. Please try this before asking the same question.

I got the max value and index of the Y variable from its source ( 1D array) . Now how can I obtain the value of X variable using the Index I obtained from the Array min& max???

I am sharing the VI file so that u can have a look at it.

Thanks in advance.

Sorry, I can't look at your VI right now. If you have a voltage array, just use the index array on it with the index returned from the y array.
