How do graph a piecewise function?

The same way you plot any function:

```
using Plots
plot(1:50, sin)
f(x) = x<25 ? sin(x) : 0.5
plot(1:50, f)
```

The function f is defined piecewise:

great! where do I find this in the documentation? I want to do other things, like make x = 1/2 and otherwise x=2

@brett_knoss here is how I approach this problem:

Q: How do I graph a piecewise function?

Q1: how do I graph any function `f`

in Julia?

Google â€śJulia Plotsâ€ť. Find this: http://docs.juliaplots.org/latest/basics/

To plot any function `f(x)`

over domain `dom`

: `plot(dom, f)`

Example `dom=1:50`

, `f(x)=sin(x)`

: `plot(1:50, sin)`

Q2: how do I create a piecewise function `f`

in Julia?

```
function f(x)
if x > 0 && x < 2
1
elseif x >= 2 && x < 5
2
else
7
end
end
```

Then: `plot(-10:10,f)`

thanks! that is handy. I found out in the mahematic opreators docs, that there is an unequal symbol !=

so I was able to put

```
f(x)=x!=0 ? .5 : 2
g(x)=x!=0 2 : .5
h(x)= f(x) *g(x)
plot(1:50,f)
plot!(1:50,g)
```

and all worked, except I canâ€™t see my plots for some reason, also I donâ€™t know how to select colors, but that shouldnâ€™t matter.

Works for me:

```
using Plots
f(x)=x!=0 ? .5 : 2
g(x)=x!=0 ? 2 : .5
h(x)= f(x)*g(x)
plot(1:50,f)
plot!(1:50,g)
plot!(1:50,h)
```

To answer your other question - you can set the `linecolor`

attribute like so:

```
plot(1:50, f, linecolor = "mediumvioletred")
```
