Tableau Desktop Professional Edition review
Can Tableau's business intelligence program justify its high price? Karl Wright takes a closer look at the figures to find out.
If you want to, you can work manually with your data. For instance, working with our oil production figures, we dragged the data category "year" onto the columns field and the names of the OPEC countries onto rows. Instantly, Tableau created a line-graph showing year-on-year production for all twelve countries. Alternatively, simply select the data you want to work with and then click "Show Me!" in the toolbar.
Tableau opens a dialogue box displaying the types of charts and graphs it thinks will best illustrate your data. You can accept the resulting graphic, or you can use it as a basis for further customisation. To customise, you just drag, drop and click. For instance, you might want to increase the number of variables your chart measures, in which case just drag those variables from the "dimensions and measures" raw data panel and drop them onto your chart. Or you may decide that each item on your chart for instance, in our case, each oil-producing country should be marked out in its own colour. To do this, simply drag the variable "measure names" onto the "colour" selector.
