Tableau uses a built-in color sequence to distinguish data series in visualizations. In this video, learn how to change the color sequence in charts.
- [Instructor] In Tableau, you create visualizations and the program applies built in color schemes. In this movie, I will show you how to change the colors that Tableau applies to chart elements. My sample file is 11_03ColorSequence, and you can find it in the chapter 11 folder of the exercise files collection. In this visualization, I have a vertical bar chart or column chart and you can see that I just have a single color of blue applied. If I want to distinguish the categories by color, then I can go over to the data panel and I have product category as my column field. So I will drag another copy of product category to the color square on the marks card. And you can see that Tableau applies colors to each of the individual product categories. The legend that appears on the right indicates which category is which. So I've blueprints in blue, orange is drone kits, red is drones, and so on. If I want to change the order of elements in the chart, then I can drag their squares on the legend. So I won't be reassigning colors, I will actually be reordering the elements. So let's say that I want to put robot kits all the way on the left. To do that, I would drag the robot kits color square up to the top, and you can see the guideline indicating where it will appear when I drop it. So I'll release the left mouse button. Robot kits appears at the top which means on the left in the end of this, so I'll click away and you can see that my items have been reordered. If I want to reassign the colors, I can go over to the legend and then click its down arrow and then click edit colors. In the edit colors dialogue box, I see the colors that have been applied within my visualization. If I want to change a single color, then I can click the items. So let's say that I'll click robot kits. And then I can select another color from my palette. So I haven't used light grey, so I'll go ahead and click that one. And robot kits. If I click OK, we'll have that color applied to it. So I'll go ahead and click OK. And you can see that the color of robot kits has been updated. If you want to change the entire color palette, you can do that as well. To do that, I'll go over to the legend, click the down arrow on the title and click edit colors. And I will now click the select color palette control. So I'll click its down arrow. And from here, I can select a color palette to apply to the overall design rather than change specific items. So I'll click colorblind, and you'll see that the colorblind palette has been displayed, but it hasn't been applied to the data items yet. To do that, you need to click assign palette, so I'll click there. And you see now that the colors have been applied. I'll click OK. And you can see that my visualization has been updated with a palette that is friendly for individuals with low color vision. You have a lot of control over the colors that appear in your visualizations. The techniques that I've shown you here, even though they were specific to a column chart will work for a wide variety of other visualizations as well. Just remember to work through the legend.
