* Show cell timing table (values) with 3D plots.
* Show cell internal_power table (values) with 3D plots.

For cell comparison function (only for same series cells):
* Show cell area comparison.
* Show cell leakage_power comparison on same conditon.
* Show cell timing table comparison on same condition.
* Show cell internal_power table comparison on same conditon.
