SetOptions for BodePlot?

[habudg (David G)]

It seems like SetOptions does not work for at least some options for BodePlot.

I assumed that the following code should set the options:

SetOptions[BodePlot, {GridLines -> Automatic, ImageSize -> 500}];

Checking the Options seems to give the expected result:

In[114]:= Options[BodePlot, {GridLines, ImageSize}]

Out[114]= {GridLines -> Automatic, ImageSize -> 500}

However, when I run BodePlot without explicity setting the options, the plot doesn’t contain Gridlines and it is not the expected ImageSize.

BodePlot[
TransferFunctionModel[{{{5. s}}, 0.004 (2.5*^9 + 1250. s + 1. s^2)}, 
  s]]

It works fine when I explicitly specify the options:

BodePlot[TransferFunctionModel[{{{5. s}}, 
   0.004 (2.5*^9 + 1250. s + 1. s^2)}, s], GridLines -> Automatic, 
 ImageSize -> 500]

I couldn’t find any notes regarding this behavior in the docs. What am I doing wrong?

SetOptions should indeed work for BodePlot, and this behavior has been corrected in the development version of Mathematica.

For a workaround, please try evaluating the following

BodePlot; SetOptions[Control`BodePlotsDump`bodePlot, {GridLines -> Automatic, ImageSize -> 500}];

BodePlot[TransferFunctionModel[{{{5. s}}, 0.004 (2.5*^9 + 1250. s + 1. s^2)}, s]]

Thanks, that works.
