Line charts and area fill charts are visualizations that show trends over time. In this video, learn how to create line charts and area fill charts.
- Much of the data you visual in Tablo will have a time, day, or date associated with it. For example, you can have a daily sale summary. In this movie, I will show you how to summarize data by creating line charts, which are perfect for time series data. In the same way area fill charts show the share of multiple contributions in reference to time or another dimension on the horizontal access. My sample file is 0902 line and you can find it in the chapter nine folder of the exercise files collections. To create a line visualization, I need to add some fields to the viz. So I will drag order date to the columns shelf, so now I have those as the columns in the text table, and I will drag order total to the data area. So there we go and you see that I have some side-by-side bar charts. If I want to change this viz to a line chart, then I can go to show me, click there, and then about halfway down in the panel, I will click lines. There we go. I click show me the hide it and there you see that we have the data broken down by year in a line chart. If I want a little bit more detail, I can go to the order data pill on the column shelf and then click the down arrow and I can select how I want to view my data. For example, if I click quarter, then you see the data broken down by quarter starting from 2017 Q3 to 2019 Q3. I can also go by month and this is usually the level that I like to work with. When I'm looking at data over multiple years, I find month is the most useful measure. So there we have our line chart and it shows how sales move about over time. I can also create side-by-side line charts, which would break items down, in this case, by product category. So if I were to drag product category to the column shelf, then you'll see that I have the ideas broken down in the columns. So I have blueprints, drone kits, and so on, but the data is still displayed using a line chart from Q3 of 2017 to Q2 of 2019. Another way to display the same data is by creating an area fill chart. So if I go to show me and I click the area chart, then you'll see, after I get rid of the show me panel, that I still have my data in a time series, but each of the time increments is broken down by product category and each of those is represented by a color. With seven categories, I'll admit, this visualization is visually confusing, however, if you only have two or three categories, then an area fill chart might give you some interesting information about your data.
