Using the following code:

```
using Distributions
dist = Normal()
plot(pdf.(dist,collect(-2.0:0.1:2.0)))
```

The plot returns as

The x-axis values are incorrect, is there a reason is it not centred at 0 as it should be?

Should be noted if I do something such as

```
plot(x->exp(x),collect(-2:0.1:2))
```

then it will return the correct plot.

You essentially have

```
plot(array)
```

In that case the xaxis is the index number into the array. You need something like `plot(xarray, yarray)`

, i.e.

```
x = collect(-2.0:0.1:2.0)
plot(x, pdf.(dist, x))
```

Alternatively you can plot a function in a range with Plots.jl via

```
pdf_eval(x) = pdf(dist, x)
plot(pdf_eval, -2, 2)
#equivalently
plot(x->pdf(dist,x), -2, 2)
```

Or, using the Distribution recipe implemented StatsPlots:

```
using StatsPlots, Distributions
plot(Normal())
```
