How to plot multiple lines on the same graph using R

In this tutorial, you will find step-by-step instructions to create line graphs, especially multiple line graphs, and to place legends right on top of the lines. We will use R and ggplot2 to create these plots.

Here are the files used in this tutorial:

A couple of books mentioned in the tutorial:

I am searching for this from the time I learnt about R studio. One very important point is we Excel users are used to plot data based on column name but here we need to stack the data in one single column. It took me many days to figure out. 😁

You just saved me from headache...THANKS!!!

So nicely explained concepts of GG Plot. Keep it up.

Pls make video on two dot plot in same graph with the help of ggplot 2

How would you make multiple lines for different variables? I.e ones that are not grouped. For example, I have a data frame with the Egg mass of a quail egg, and I want to compare the shell mass with each of the egg components (Shell mass, yolk mass and albumen mass). Each of those components are under a new column in my data frame: How would I plot them all on the same graph against the egg mass?

Thank you very much! your graph is really nice.
I have a question:
How can I create a double axis graph?

[TOPAZBLUEFOX]

It is possible to plot two density histograms from two different data frames in a single graph?

[harrisonbooth]

can I extend this to more than 3 sets of stock data?

nice tutorial! how to export graphs in png /jpg?

Sir, I made a ggplot using the geom_line() function two times to show the two different lines on the same plot. My data is bivariate data. I am unable to put the legends for both two line. Kindly help me to resolve it. If you share your email id, I can share with you my codes. Sir, I am at the very initial stage of programming. Plz help if possible

Do you know how to plot multiple lines in the same graph, and start from the same value, for example $100?
Then like you can compare Netflix, Amazon, Apple from 2009 to 2019?

[ManhwasForLife]

which software you have used for creating this graph?

[sarabdn]

Thanks for this video!!
Is there a possibility to add multuple lines but from another Dataframe?
I have one large dataframe but made subsets. I want to plot the lines of the subsets which is based on a condition of a variable.
Or is there a possibility to load one big dataframe and to make different lines based on a condition?

You saved me Boss - Times when I realize that Python is a shit-tool for basic visualization

Really good video. But you rushed the part on creating multiple lines.
