During the Evaluation period of Statgraphics 19, you may switch between languages by selecting *Edit - Preferences* from the main STATGRAPHICS Centurion menu. Click on the *Language* tab and select the language you wish to use. You may select different languages for the user interface and for the output. Once the evaluation period is over, the languages you have access to will depend on the license that you purchase. Access to more than one language requires that you purchase a license for either the Bilingual Edition or the Multilingual Edition.

**Important note:** When installing a new build, do not uninstall the previous build. The new build will replace the previous build and will not require reactivation.

**Version 19.3.03 posted March 17, 2022**

**Version 19.2.01 posted March 10, 2021**

New procedures:

**Dynamic Pareto Chart**(under*Statlets - Data Columns*)**Dynamic Radar/Spider Plot**(under*Statlets - Data Columns*)**Time Series Spiral Plot**(under*Statlets - Data Columns*)**Support Vector Machines**(under*Interfaces - Python*)**Fitting Non-Normal Mixture Distributions**(*under Interfaces - R)*

**Version 19.1.03 posted December 29, 2020**

New Features:

- In
*Multiple Variable Analysis*, may now choose whether to display sample sizes and P-values in correlation matrix tables. - In
*Cluster Analysis*and*K-Means Clustering*, may now draw convex hulls around each cluster in 2-D scatterplots. - Optional value labels added to barcharts in
*Barchart*,*Multiple Barchart*,*Frequency Tabulation, Frequency Tables*,*Contingency Tables*and*Crosstabulation*. - Condition number added to summary of experimental designs in DOE Wizard.
