Description of the bug

There appear to be multiple errors when trying to plot 3D far-field data using SolutionData.plot_3d()

• When no arguments are passed and the curve is db(RealizedGainTheta) the formula is set to mag which causes all negative numbers to be positive.
• There seems to be an error related to the array dimension in some cases that needs further investigation.

Steps To Reproduce

While modifying the simple dipole example, the following code

report_3d = hfss.post.reports_by_category.far_field("db(RealizedGainTheta)",
                                                      disc_sweep.name,
                                                      sphere_name="3D",
                                                      Freq= [center_freq],)

report_3d.report_type = "3D Polar Plot"
report_3d.create(name="Realized Gain (dB)")

report_3d_data = report_3d.get_solution_data()
new_plot = report_3d_data.plot_3d()

produces the following error:

PyAEDT ERROR: Cannot reshape array of size 32761 into shape (181,91) on plot_3d
PyAEDT ERROR: Last Electronics Desktop Message - [error] cannot reshape array of size 32761 into shape (181,91) on plot_3d

[Devin-Crawford]

In the SolutionData class, the method plot_3d() applies the method self.mag(curve) by default. This, in turn, returns magnitude, which applies mag() to dB, which only returns positive values and does not return the intended: db(RealizedGainTheta).

[Devin-Crawford]

The problem is that visualization.report.field.FarField.get_solution_data() returns only the trace from the report that was already created. In this case, the underlying data is db(RealizedGainTheta) so no further operation is required. The method plot_3d() however, applies mag to the underlying data which is incorrect.
