How to create bar charts

How to create bar charts

- [Instructor] Here's how we create bar charts. Bar charts have two features. They have an axis where we plot the value, and in general, we have a dimension. That breaks the bar into individual bars based on the number of independent values of that dimension. So, to build a bar chart, first we put a measure on the row or the column. So, in this case, we'll put Sales onto our column and we have a single bar chart. Now, we add more dimensions to break it into its components. So, for example, let's break it down by Sub-Category. We can add further dimensions, which will create more bars. If I add them to the rows, such as Category onto the row, we then group first the bars by the Category, and then break them down by the Sub-Category. I can also add dimensions to the columns. If I put Region onto the columns, now I have multiple bars for each of the Regions, each of the Sub-Categories, and then grouped by the Category.
