These Dimensions act as independent variables, whereas the Measures are dependent on those Dimensions. For example, imagine having a horizontal bar chart that is showing Sales across Region. Since our Orders sheet of Sample - Superstore.xlsx data has four regions, we will get a bar chart showing four bars and the length of the bar representing the sales across regions. Now, if we get another Dimension, say Category, and place it right after the Region field in the Rows shelf, we will add an additional granularity of Category into the view and now instead of 4 bars, we will get 12 bars as we have three categories in our data and at this point, the Sales will be computed for each Category within a Region. Also, in the same view, if we remove Region, then we will have a bar chart with three bars showing sales across categories...
