![]() ![]() And the halo effect goes all the way around.īut a couple drawbacks to this. Here’s a good example where you’ve got three states that are kind of bunched together. For marks that are overlapping, it doesn’t draw the border around each individual circle, it draws the border, or what they call a halo, around the entire overlapping group. Let me show you if I choose a black halo. This is a little bit different than Border. We also see something called a Halo effect. I’ll make these circles on each state a little bit bigger and color these circles by the Region dimension as well.Īnd if I go to the Color Marks Card, I see there’s a border effect– same thing that we saw on a scatter plot. On a new sheet, I’m just going to double-click on the State dimension, which will create the first type of map. And the trick was, we were able to color the border the same thing as the underlying circles below it– gives it a nice little polished effect.Īnd because scatter plots are technically used to make maps, you can use this exact same formatting trick to help make your symbol maps more engaging. And I’ll go to the All Marks (Shelf) to make all these circles a little bit bigger just so that we can take a closer look.īut notice, now, we’ve got two different marks laying on top of each other. But just to be sure, I’ll right click on one of the axes and choose Synchronize Axis just to make sure. To convert this to a dual-axis chart, just click on the second pill and click Dual Axis. So now if I combine these and synchronize the axes, we’ll have the open circle at full opaqueness surrounding those circles at 50% opaqueness. But the mark type is Circle– I’m sorry– is the open circle instead of that closed circle. So those marks are in the exact same position. So first row scatter plot, Circle is my mark type. And maybe you can start to see this come together now.īut I’m going to change the Opacity back to 100% for the second row, only. Just to be precise, I’ll change that to 50%.īut then on the second row, I will change the Mark type from Circle back to Shape and click the Shape Marks Card to ensure that it is set to Circle. So on the first row, I can get rid of the border on the Color Marks Card. And those Marks Cards can be edited independently of each other. But what’s important about this is now that I’ve got two measures on the Rows Shelf, they each get their own set of Marks Cards. So now we’ve got the same chart on two rows. I’ll just duplicate the Sales pill on the Rows Shelf by holding down the Control key while I click on it and drag it right next to itself. What I’m going to do is duplicate either the Profit measure or the Sales measure on the Columns Shelf or Rows Shelf, respectively– doesn’t matter which one you do. We have another video, here, that explains some creative ways on how to use a dual axis. It’s another trick that leverages the dual axis. ![]() Well, that’s what I’m going to show you how to do. And I’m not in love with those all-or-nothing borders. So I might drag this down to, say, 50%, which will give those circles a lighter look. So if you’ve got any overlap, adding some transparency helps reveal underlying marks. But another thing I like to do is make the interior of those circles a little bit transparent, which is particularly effective if you’ve got lots of different marks on the view. So I could give these a color, such as black, just so that they pop a little bit more on the view. But watch what happens when I click on the options. And under Effects, there is an option for Border. Let’s see what our options are, here, for a scatter plot. One of the formatting things I like to do on a scatter plot, though, is add a border. So if we wanted to make associations– so color associations– between those regions in those different views, we would need to add the Region dimension to the Color Marks Card. ![]() ![]() Now let’s say that we are using this scatter plot on a dashboard that contains other visualizations that are also colored by the Region dimension. I will also change the mark type from Shape to Circle, make that circle a little bit larger so that we can see it and maybe change the level of detail to Region by just putting the Region dimension onto the Detail Marks Card. I’m just going to double-click on Sales and double-click on Profit. And in this video, I’m going to provide a formatting trick to help you make more engaging scatter plots and symbol maps. ![]()
