True or False: We get different colour pallete options if we drop a discrete field on "Color" in the marks card compared to if we drop a continous field on Color.
Answer(s): B
Yes! We get different color palettes. They are:*From the official Tableau documentation*To change the color for a value1) Click on an item on the left, under Select Data Item.2) Click a new color in the palette on the right. In Tableau Desktop you can hover over a swatch to identify the color.3) Repeat for as many values that you want to change.4) In Tableau Desktop, click OK to exit the Edit Colors dialog box. In Tableau Server or Tableau Online, simply close the dialog box.AND

Which of the following are stored in a .tds file? Choose 3.
Answer(s): A,C,E
If you've created a data connection that you might want to use with other workbooks or share with colleagues, you can export (save) the data source to a file. You might want to do this also if you've added joined tables, default properties, or custom fields--such as groups, sets, calculated fields, and binned fields--to the Data pane.Visualisations and Data extracts are NOT saved in a .tds file!

In order to avoid any confusions, what should you do after creating a Dual-axis chart?
Answer(s): C
After creating a dual axis chart, make sure to synchronise their axis since they both might not be having the same y-axis.To align the two axes in a dual axes chart to use the same scale, right-click (control-click on Mac) the secondary axis, and select Synchronize Axis. This aligns the scale of the secondary axis to the scale of the primary axis.In this example, the Sales axis is the secondary axis and the Profit axis is the primary axis. If you would like to change which axis is the primary, and which axis is the secondary, select the field on the Columns or Rows shelf that is the secondary, and drag it in front of the primary field on the shelf until you see an orange triangle appear.In this example, you can select the SUM(Sales) field on the Rows shelf, and drag it in front of the SUM(Profit) field. The Sales axis is now the primary and the Profit axis is the secondary.

Which of the following are compelling reasons to use a Stacked Bar Chart?
Answer(s): A,C
Stacked bar charts will usually have lesser number of bars compared to a normal bar chart:Normal bar chart - 9 barsStacked Bar Chart - 3 barsWe can easily see a 'part-of-a-whole' methodology being used here as well - we are seeing the breakdown of Segments within each Category.To easily visualize trends over time - This is the definition of a line chart. To visualize each discrete category using a separate bar - This can be accomplished using a simple bar chart, why use a stacked one?
True or False: It is not possible to blend axes for multiple measures into a single axis
Answer(s): A
We can very much blend multiple measures into a single axis. Such charts are called Combined-Axis / Blended-Axis charts. Follow along:Measures can share a single axis so that all the marks are shown in a single pane. To blend multiple measures, drag one measure or axis and drop it onto an existing axis.Instead of adding rows and columns to the view, when you blend measures there is a single row or column and all of the values for each measure is shown along one continuous axis. For example, the view below shows quarterly sales and profit on a shared axis.Note: If you drag a measure on to the canvas and only see a single ruler indicator instead of the double ruler indicator shown below, Tableau creates dual axes instead of a blended axis. For more information about how to create dual axes, see Compare two measures using dual axes.
