Now that we're finished with the top and left sides of the screen, let's move to the main workspace, the biggest section of this screen. In the top-left is a section, we had the Pages shelf, which are hid, but I can put it back very easily and we can just drag it back up there. This shelf is super fun in the desktop app because it allows you to animate a graph. Let's see how about 20 years of time trended data but you can't use the x-axis to denote time for whatever reason. Put the year on the Pages shelf and animate it instead. It's very cool, but unfortunately, this will currently not work when it's published to a Tableau Server, be that Public or Tableau Online, or your company's own Tableau Server. It only works in the desktop app. Below the Pages shelf is the Filters shelf. This is where you drag and drop a pill that you want to use to filter your data. Pretty straightforward. Next is the Marks card. At the top of the Marks card, there's a dropdown menu that will allow you to select the mark type. Right now it is Text because that is default when you drag a single measure onto the view but you can change it to anything else in the menu. It won't work too well until you have other data in there with it but we'll look at that soon. Below the Mark type selector, there are five buttons. These are all clickable or you can drag a pill on top of them to say that you want that field to be represented by color, or size, or text. Don't be afraid to try clicking on these too. The only one that doesn't do anything special when you click on it is Detail. The Marks card is one of the powerhouses of Tableau. So get comfortable with it, and don't be afraid to try new things and click around. At the bottom of the Marks card, you'll see all the things you've put on the card lined up in a stack. From here, you can edit fields in line and you can change whether they're on the detail, or the color, or the size, or whatever. The last column actually forms the majority of the screen. At the top is the Columns shelf followed by the Rows shelf, followed by the View or the Worksheet shelf. Just a note, I tend to use those words interchangeably, View versus Worksheet. The Column shelf is for information that you want to be organized in columns going across the screen and is basically synonymous with the x-axis. The Rows shelf is for information that you want to be organized in rows going down the screen and is basically synonymous with the y-axis. The View itself is where you see everything happen. This concludes part 3. Okay, almost done with our little tour of the Worksheet space. There's two more tiny rows at the bottom of the screen. The first row at the bottom of the window starts with Data Source. Clicking this will take you to the data connection window for your current data source. You can make changes here or fix a broken connection, and then go back to the sheet like we did before. To the right of the Sheet 1 tab is a New Worksheet button, followed by the New Dashboard, followed by New Story. You'll notice that there are often many ways to accomplish the same thing in Tableau, because everyone approaches problems differently. We won't cover stories in this course, but you can see here that a worksheet will house basically one chart. A dashboard then can house many worksheets as well as text objects, images, URLs, embedded webpages, buttons, etc. We'll make one next week. Now, finally, the last row. The first thing you'll see is a count of marks on the View, followed by a little summary of the dimensions of the View, and then the sum of the most recent measure you placed. All the way on the right, you'll find a set of four buttons which are used for navigating back and forth when you have about a zillion pages in your workbook, followed by three options for how you want to view all of those pages. These are pretty self-explanatory.
