15:00:04 Hi! Everybody! Welcome back in this video. I'm just gonna give a brief introduction to the desktop application.
15:00:11 If you're using the online version of the application, it will be pretty similar.
15:00:15 But some things will look slightly different. You'll also need to drag the data from the data version of the folder of the folder and the repository, the data folder and the repository into the online web app if you'd like to play around with data so what you need to do
15:00:32 is first open, the app, and when you open the app you should see something like this.
15:00:36 And here's what it looks like. So once you have the app open, you'll see things like connect.
15:00:42 So connect allows you to connect to a data file. You'll also see something like to a server.
15:00:48 So I do not believe that this is available in the public version of the app, but it's possible.
15:00:54 So also I want to. Let's see what it's like to connect to a data file.
15:01:00 So we're gonna connect to the text files. And you can see I'm already in the data folder of their repository.
15:01:08 So for this example, I'm just going to click on the Galton data.
15:01:11 And so once that opens, you'll see that now I have the Galton data.
15:01:15 You can also see all the other files within my version of the data repository. And if I want to play around and make some visualizations once the data is loaded in this area, I'm gonna click on sheet. One so this is a worksheet.
15:01:33 Okay. So I'm just going through making sure I'm covering everything.
15:01:36 This is a worksheet. This is where you're going to make and play around with all your visualizations.
15:01:42 I will learn more about this in the coming video. So, for instance, we can just make and play around and make a quick visualization.
15:01:50 So this it maybe will look unfamiliar to you if you haven't worked with tableau before. Don't worry.
15:01:55 We're going to cover everything that I'm about to do. So I'm going to make a quick visualization of the heights against.
15:02:03 Your father's heights, and you'll see it's just this one little dot.
15:02:09 Well, that's because tableau does something called aggregating by default.
15:02:13 But if I turn that off, I now have my scatter plot, which should look familiar, and I'll notice that it.
15:02:22 This access seems a bit off, so I'll not include 0 in my axes.
15:02:29 And again we'll go over this in more detail on specific videos.
15:02:34 Now I have this nice little plot of height versus father's site, and maybe I want to make it so that these circles are filled in.
15:02:45 So I click on shape and choose a filled in circle.
15:02:51 And then maybe I want to have the points be colored by the sex variable.
15:02:57 So now you can't see it. I'll move myself down to the left hand corner.
15:03:02 Females are blue, and males are orange, and maybe I also want to be conscientious of people who can't tell the difference between orange and blue, so maybe I'll also bring sex over to shape.
15:03:12 So now the points are both the shape and the color, and maybe what I can do is added the shape.
15:03:22 So maybe females will be filled in, and mails will also be filled in.
15:03:28 Okay, so you can see quickly with tableau. I was able to make this scatter plot by dragging and dropping a bunch of things, and we'll learn about how to do this in a coming video.
15:03:38 So let's go back just to make sure we covered everything I wanted to cover.
15:03:43 So we played around, and we quickly made this chart, and maybe slightly different in our version maybe the shapes aren't the same.
15:03:51 But we quickly made this chart, and now we're ready to going more with tableau.
15:03:56 So I hope you enjoyed this video. I enjoyed having you watch this video.
15:04:01 And the next video we'll talk a little bit more about tableau, how it works with workbooks, and what is inside of a workbook.
