Frequency response analysis post processing in hyperview and hypergraph

Hi sir, 

When I am seeing the contour plot of maximum acceleration in X direction at 1000Hz, I get a maximum value of 2.72E3.

Now I selected a node from the region where we find maximum acceleration (red zone) and plot a graph in X direction at 1000Hz using hypergraph. 

I should get maximum peak as 2.72E3 because the contour plot says so. 

But I am getting the peak at around 3.7E4

Why is this difference coming?

    Please set animation mode to transient and change the legend to dynamic scale for plotting Dynamic analysis output in HyperView. This should vary result over the range of defined frequency.Refer attached screenshot.

    Also change the animation mode to Transient and check the results in HyperView.

     

    If you see the contour, the minimum is seen as ~ 4.7e3 and the same magnitude is seen in HG at 1000Hz.
