### Lines
A simple line plot of the 3 columns.
```julia
plot(rand(100,3))
```

### Functions
Plot multiple functions
```julia
plot(0:0.01:4π,[sin,cos])
```

### Global
Change the guides/background without a separate call.
```julia
plot(rand(10); title="TITLE",xlabel="XLABEL",ylabel="YLABEL",background_color=RGB(0.5,0.5,0.5))
```

### Vectors
Plot multiple series with different numbers of points.
```julia
plot(Vector[rand(10),rand(20)]; marker=:ellipse,markersize=8)
```
![](../img/gadfly_example_4.png)
### Vectors w/ pluralized args
Mix arguments that apply to all series with arguments unique to each series.
```julia
plot(Vector[rand(10),rand(20)]; marker=:ellipse,markersize=8,colors=[:red,:blue])
```

### Build plot in pieces
You can add to a plot at any time.
```julia
plot(rand(100) / 3; reg=true,fillto=0)
scatter!(rand(100); markersize=6,color=:blue)
```

### Heatmaps
```julia
heatmap(randn(10000),randn(10000); nbins=200)
```
![](../img/gadfly_example_7.png)
### Lots of line types
Options: (:line, :step, :stepinverted, :sticks, :dots, :none, :heatmap, :hexbin, :hist, :bar)
Note: some may not work with all backends
```julia
plot(rand(20,4); linetypes=[:line,:step,:sticks,:dots])
```
