I want to plot some data that contains zeros, with log-axes. This does not work easily:

```
using Plots
xs=[0.0,1.0,2.0]; ys=xs.^2;
plot(xs,ys; xaxis=:log)
#ArgumentError: At least one finite value must be provided to formatter.
```

The same for data with infinite values (which is the core issue).

Now, what is the kind of output I’d like? Well, infinite values like `log(0.0)=-Inf`

should get a point to the left/right/above/below that smallest/largest finite value that occurs, and I’d ideally get an extra labled tick and an axis break for this.

Apart from the nice axes/ticks, this can be achieved by iterating over the data, computing the smallest/largest finite values, computing a threshold that is somewhat below/above and truncating the infinite values. However, the correct transformation depends on which axes are supposed to be logarithmic, and which ones are supposed to be absolute; so it is really the plot function that should do this transformation.

Why do I want this? First, logarithmic plots with zeros. Second, beyond-threshold sometimes wants to be represented as infinity. E.g. when plotting run-times of algorithms, it is quite sensible to represent out-of-memory as infinity.

So my question is, 1. does there exist a plot option for this? 2. If not, is there a recipe flying around for this?
