Multiple map layers

0:00Hey it's Tim here and in this video I'm

0:01here to talk about a new exciting feature

0:04which allows

0:04you to layer in maps, yes that's right you

0:07are now able to add additional layers to a

0:10single mapping

0:11object inside of Tableau. Let me show you

0:13how this works, in a previous video I

0:15actually created

0:16a data set inside of Tableau prep in the

0:18browser and one of the things I'm trying to

0:19do with the

0:202020.4 release is just see how much of it

0:23can I do in the browser and so far 100% of

0:26everything

0:26I've been able to do has been in the

0:28browser. So let's go ahead and let me show

0:30you how to use this

0:31feature in the browser. Hey it's Tim here

0:33just a quick one before the video, 95% of

0:36the people who

0:36watch my videos aren't actually subscribed

0:38to my channel and I've got about 7 000

0:40subscribers,

0:41they only represent five percent so join

0:43that group you know join that exclusive

0:45group subscribe

0:46and try and get the subscriber numbers up

0:48on my channel it'll be really really great

0:50for me,

0:50thank you. I'm going to go to the default

0:52section here earlier on in another video in

0:54this playlist

0:55I created this prep in the browser file

0:57here so I'm going to click on that and you

0:58're going to see

0:59this data set this is actually what I'm

1:01going to be using today. What I did is I

1:03took a spatial file

1:04from the US government website and I joined

1:06it onto superstore sales to give us the

1:09geometry

1:09for different states in the US so we've

1:11actually got that as a geometry even though

1:13Tableau has

1:14that in the geocoding database we brought

1:16in the geometry specifically. What I'm

1:18going to do is I'm

1:19actually going to create some new workbook

1:20in the browser here and we're going to show

1:22you how this

1:23new mapping capability works. So the first

1:25thing to do is just to build a basic map

1:27you know how

1:28to do this double click a city and Tableau

1:30automatically interprets this as a map and

1:33will

1:33start plotting the points because it's a

1:35city it plots the points if I was to remove

1:37this and I was

1:38to double click state instead it would

1:40actually draw a same thing again map but we

1:43can of course

1:44change this to let's see like an actual map

1:47with different layers and we can actually

1:50color this

1:50a little bit. I like to give these maps a

1:52little bit of pop I call it and just make

1:54these borders

1:55white and go back to the map layers here

1:58and we just want to make sure we wash out

2:02the colors a

2:02little bit so we don't have sort of the

2:04distracting background in there just let

2:06that wash out a

2:07little bit and you might argue okay this

2:09isn't great for visibility but that's fine

2:12I'm just

2:12trying to go for something that looks nice.

2:15I'm going to drag a state onto labels which

2:17is great

2:17and then what we will probably do is I will

2:21drag region onto color just to give us the

2:24contrast we

2:25need to show you how this works. So there

2:27we have a nice map of the states again I'm

2:28doing this all

2:29in the browser. Now the cool thing in 2020.

2:334 is I can actually drag in additional

2:36mapping context

2:38onto this information. So I've already got

2:41the state here okay and I did this just

2:43using the

2:44state field I haven't used my geometry

2:46field yet I'll show you how to do that in a

2:47second.

2:48Let me go and grab the city and I click and

2:51drag what's this red circle here I have

2:54this new

2:54ability to add a marks layer. Now if I go

2:57ahead and drop this on there you'll see

2:59several things

3:01happened. Number one it plotted the cities

3:05on top as a layer on top of the map that we

3:08already

3:09created previously. The reason that

3:11happened is because you can see here that

3:13city is actually

3:14on top in terms of layers. Now if I want to

3:16change the order of these I can of course

3:18drag them

3:18around so if I just grab state and I drag

3:20it around you can see an orange line

3:22appears and I

3:23can actually put this up there so it tells

3:25you where it's going to put it and you can

3:27even see

3:28here that now the thing that's on the top

3:30here is California and everything else is

3:33underneath. I'm

3:34going to change that back here just to make

3:36it easy to see what's going on and because

3:39we've got

3:39our cities what I'm going to do is I'm

3:41actually going to change the color of my

3:43cities just so

3:43it's easier to see. I'm going to make them

3:47red and it's not going to work nicely with

3:50this over here

3:50so maybe let's try and find a shade of

3:53maybe green let's like maybe yeah maybe

3:56that it's difficult

3:57because everything has a color so let's

3:59just choose black. I think black is quite

4:01cool actually

4:02let's go with black and we'll just drop the

4:04opacity down so it's not too harsh. Now the

4:07thing I want

4:07to do now is go back to my state layer go

4:09to color and I'm just going to wash this

4:12out a little bit

4:12so what you can see here is I'm adding

4:14context to the map actually I'm adding a

4:16little bit of variety

4:17to the map and we can keep adding

4:20information we're not done yet. What I can

4:23now do is go get

4:24my geometry that I joined inside of Tableau

4:26Prep in the browser and bring it in again

4:29onto my marks

4:30layer and now I have a spatial layer in

4:32here. Now the spatial layer is sort of

4:35defunct because it's

4:37essentially just showing us something we've

4:39already got but what I'm going to do is I'm

4:41actually going to go back to my state layer

4:44over here and switch this from a map to a

4:46circle.

4:47Now when we do that you can see nothing

4:50changes we lose the color because our

4:53geometry layer is

4:54on the top so let's take that all the way

4:56down to the bottom and go into that

4:58geometry layer

5:00and let's color this by state so we can get

5:02some of that color that we had previously

5:04and you can

5:05see it's sort of not ideal so let's go back

5:07to region and let's do that that way let's

5:09just swap

5:09that with region and now we get some of

5:12that color we had before. Notice now that

5:14we have the state

5:17color here and it's also keeping the color

5:19that we match to the region because I'm

5:22using the color

5:23in two different places you see region and

5:25state here region and geometry here and so

5:28the colors

5:28are matching so this actually acts as a

5:30really nice way of selecting the states and

5:33it's a really

5:33sort of nice interactive tool. Now what you

5:36're probably wondering is look how do I

5:38disable

5:38selections if I've got so many things on

5:40the map here how do I make things work a

5:42little bit better

5:43well the first way is you can obviously

5:45change the icon so for the state let's go

5:47ahead and

5:48change this to a square and you can see

5:50that this changes to a square and that

5:52works a little bit

5:53better we can even increase the size just

5:55to give it a bit of contrast and now you

5:57can see how that

5:58works really really nicely. Now the next

6:00thing we can do is we can disable the

6:02ability to select

6:03things on a specific layer so let's go

6:06ahead and say that we can't select this

6:08state square so you

6:09can see right now I can select that square

6:12let's deselect it let's go back and what we

6:15need to do

6:15is we just need to click on this drop down

6:17here for the state and you can see you get

6:19this nice

6:20drop down window it gives you the ability

6:22to move it up and down hide the layer

6:25rename the layer

6:26remove the layer or disable selection. So

6:29this allows us to disable the ability to

6:32click on this

6:32so you see now I'm clicking through the

6:34square to the object behind it which is

6:36actually our

6:37geometry layer so that's a really really

6:39nice feature that you can use there it's a

6:41really

6:41nice quality of life improvement if I go

6:43back to my geometry and I go to color I can

6:46actually add

6:46that white border back on so everything has

6:48that nice border that we had before and now

6:51this starts

6:51to look a little bit more interesting. Now

6:53the interesting thing about this feature is

6:55as soon as

6:56I saw this feature I thought come on there

6:57's got to be more we can do with this right

7:00and when are

7:00we going to get this for charts and visual

7:02izations right because of course this is so

7:05completely

7:05changing the way we've known the marks pane

7:08to work we've always known when you do

7:09things like

7:10a dual axis that you actually get you know

7:13two marks panes one for one of the items on

7:15the dual

7:16axis one for the other sometimes when you

7:17add lots of pills and rows and columns you

7:19get a whole long

7:20list of items here on the left hand side

7:22but this is actually allowing us to layer

7:25information on

7:25top of each other which gives you a world

7:27of possibilities when it comes to labeling

7:30and adding

7:30context to visualizations okay so if you go

7:33out to twitter and you look online you'll

7:35find some

7:36absolutely amazing hacks that people are

7:38coming up with just with the mapping

7:40capability to show you

7:42how it works I like to keep videos to the

7:43book as it were because you know these are

7:45guides for

7:46people who are getting new into tableau or

7:48trying to use this at work just to get a

7:50problem solved

7:51so I won't be hopping into the hacks but

7:53absolutely go on to tableau public go on to

7:56tableau and

7:56twitter and see what people are coming up

7:58with because I'm telling you it's exciting

8:01stuff when

8:01this comes to standard charting this is

8:03going to be a really really nice feature to

8:06have but you've

8:07seen it there pretty much a very very

8:09simple feature we have layers they're easy

8:12to add they

8:12work like you'd expect them to in tableau

8:14they're very simple to work with you can

8:16drag them around

8:17like I'm doing so here obviously that

8:19changes the hierarchy and of course you can

8:21change the

8:21ability whether they're selected or not and

8:24it makes it really really easy to work with

8:26that's

8:26pretty much the feature in a nutshell if

8:27you've enjoyed this video you know what to

8:29do hit

8:30subscribe hit the like button otherwise if

8:32you haven't you know hit the dislike button

8:34twice and

8:35drop a comment below let me know what you'd

8:37like to see instead I'll catch you in the

8:38next video

8:39and be sure to check out other videos in

8:41this playlist as well and there's lots of

8:42great content coming out over the next few
