Tableau 7.0 is released in January 2012 with 40+ new features. Most interesting for me is the doubling of the performance and the scalability of Tableau Server with 100+ users deployments
(while adding multi-tenancy, which is the sign of the maturing toward large enterprise customers) and adding “Data Server” features, like sharing data extracts (Tableau-optimized DB-independent file containers for datasets) and metadata across visualizations (Tableau applications called workbooks), automatic (through proxies) live reconnection to datasources, support for new datasources like Hadoop (since 6.1.4) and Vectorwise and new “Connect to Data” Tab:
Tableau’s in-memory Data Engine (required to be used with Tableau Professional) is the 64-bit executable (if running under 64-bit Windows). Most appealing and sexy new features in Tableau 7.0 are related to mapping. For example I was able quickly create Filled Map, showing the income differences between states of USA:
Other mapping features include wrapped maps, more synonyms and mixed mark types on maps (e.g. PIE instead of BUBBLE), the ability to edit locations and add new locationsas well as using Geography as Mark(s), like I did below:
Tableau 7.0 supports new types of Charts (e.g. finally Area Charts) and has new Main Menu, which actually causes a lot of changes where user can find menu items. Tableau added many analytical and convenience features for users, like parameter-based Ref.lines, Top N filtering and Bins, Enhanced Summary Statistics (e.g. median, deviation, quartiles, kurtosis and skewness are added):
Trend models are greatly improved (added t-value, p-value, confidence bands, exponential trends, exporting of trends etc.). Tableau 7.0 has now 1-click and dynamic sorting, much better support for tooltips and colors.
