## Plotting functions

In data science and statistical modeling, there are several instances where an analyst needs to use several functions for both transforming and exploratory analytics steps. So, one can plot them in Gadfly in a very simple way, which can used to plot separate functions as well as to stack several functions in a single plot.

### Getting ready

As we already specified, we will use the Gadfly plotting library for this recipe too. So, follow the installation steps from the previous recipes.

### How to do it...

Let's start with a basic function plot to get familiar with the syntax. So, a good basic function to start is the

`sin()`

function, which can be invoked as*sin*. The function can be included directly in the plot command, along with the upper and lower limits of the*x*axis. The syntax is:`plot(function, lower_limt, upper_limit)`

. This can be done as follows:**plot(sin, 0, 30)**Similarly, if we want to plot multiple functions on a single plot, we can do just like we did in the previous...
