how to process noise analysis of instrument amplifier ad8421 with multisim？

[KanHaiSea]

hi dear NI friends

Recently I am going to analysis the noise of instrument amplifier ad8421, while i can not plot the correct voltage noise-frequency figure.

For example, how to plot the GAIN=100 noise-frequency curve？

Thank you！
