The following is a list of other small visualization improvements:

• Tableau 10.5 introduced the Viz In Tooltip feature. Unfortunately, in previous versions, it was impossible to hide a worksheet that was only used in a tooltip. You can now hide those Worksheets in every Tableau 2018 version.
• From Tableau 2018.1, saved clusters are no longer just groups, but are a special field with this icon:  You can reuse saved clusters, and, with a right-click, you can refit the clusters to take the new data into account.
• You can revert your workbook to Tableau 10.2 by using the option Export as Version in the top File menu. From Tableau 2018.2, you also get clear information about the compatibility and lost functions.
• When you hover over a grayed option in the Analytics pane, Tableau now gives you information about why you can't use that option.
• Tableau now displays the link to the Driver Installation page in the Connection menu, for a specific connection.
• You can display negative values on a logarithmic axis, from Tableau 2018.2.
• Dates can be represented in ISO 8601 format, from Tableau 2018.2.
• Geocoding has been improved in the 2018.2 version, with Japanese municipalities, wards, seven-digit postal codes, and 2018 Pennsylvania Congressional Districts.
• Cross-database Joins and multi-dimensional expression queries for cubes have improved performance since Tableau 2018.2.
• In Tableau 2018.3, you can connect to the ESRI Geodatabase, KML, and the TopoJSON file.

Now, we'll look at the new features available for Dashboards.
