The following stream plot is empty and the x-axis exceeds $[-0.1,0.1]$ significantly.

StreamPlot[{y, -100000 x - y}, {x, -0.1, 0.1}, {y, -100, 100}]

Using ListStreamPlot as suggested by Lou did not work either, i.e. I couldn't find any parameters that yield a sensible visualization of the vector field. Note that the problem does not occur for

StreamPlot[{y, -x - y}, {x, -1, 1}, {y, -1, 1}]

How can this scaling issue be addressed in order to obtain a sensible visualization of the vector field?

Let's have a look at StreamPlot

enter image description here

Means we can have a table of values

data = Table[{y, -100000 x - y}, {x, -0.1, 0.1, 0.05}, {y, -0.1, 0.1, 0.05}]


and we can plot them


enter image description here

With that knowledge you can play with your values

Table[{y, -100000 x - y}, {x, -0.1, 0.1, 0.01}, {y, -0.1, 0.1, 0.01}],  
DataRange -> {{-0.1, 0.1}, {-1, 1}}]

enter image description here

  • $\begingroup$ For xy-axes with $-0.1<x<0.1$, $-100<y<100$ the vector field should look like a spiral. Is there a way to obtain this visualization? I tried your suggestion but couldn't find any parameters that yield a nice visualization. $\endgroup$ Commented Oct 14, 2015 at 20:51

It seems that the average separation of your vertical streams is around 50 (in units of x). Simply expand the x range to e.g. -500 to 500

StreamPlot[{y, -100000 x - y}, {x, -500, 500}, {y, -1000, 1000}]
