@9prady9 , I'll pick up this review if you have no objections |

@willyborn I'm happy with the changes you have made to the setup_vector_field routine. The field example is working with that fix. I see that you have made other changes to the join method to check the dimensions and handle the case where the stride is not 1 in the first dimension. I think there is more work to be done on the other versions of the join routine to fully support this. There should probably also be additional tests added to the join test suite for this. I suggest that we just merge the setup_vector_field changes here and open a separate issue for the join method changes. |

OK.
I have to resync to the latest env. so this could take some time looking at
the recent build problems, some experience.

vectorField is a graphical function, so it is not included in the test
series. The only way to test it, is by using it in examples.
The are 3 versions of vectorField, dependent on the provision of the
coordinates
1. full coordinates in 1 array
2. X & Y axis as separate arrays
3. X, Y & Z axis as separate arrays
The corrected error is the part that combines all those different
provisions (join) into 1 common set that is forwarded to forge to display.
So in the example I added the 2nd form so that it can be verified.
PS: The last form 3D is not included since forge has problems displaying
those. I noticed that multiple 3D examples are broken.

In examples/graphics/field.cpp
<#3375 (comment)>:
> myWindow(0, 0).vectorField(points, saddle, "Saddle point");
myWindow(0, 1).vectorField(
points, hbowl, "hilly bowl (in a loop with varying amplitude)");
+
+ // 2D coordinates
+ myWindow(1, 0).vectorField(2.0 * flat(x), flat(y), flat(x),
What are these extra plots for?
