Although Tableau's default mark sizes are good, the option of changing (increasing or decreasing) those mark sizes is also useful. This can help the reader see the data better and reduce the confusion caused by overlapping or small marks.
Let's use the sample file Sample – Coffee Chain (Access). Open a new worksheet and select Sample – Coffee Chain (Access) as the data source.
Once the data is loaded on the worksheet, perform the following steps to increase or decrease the mark size:
- Click on the Show Me button to bring the Show Me toolbar on the screen.
- While holding the Ctrl key, click on Product and Market Size from Dimensions and Profit from Measures.
- Click on the circle view icon on the Show Me toolbar to generate a visualization as shown in the following screenshot:
- To vary the mark size by the number of records in each Product and Market Size values, drag-and-drop Number of Records from Measures into the Size box under the Marks pane.
- To increase the size of the marks, click on the Size box to show the slider and drag the slider to the right as shown in the following screenshot:
- To decrease the size of the marks, drag the slider to the left.
