Analytics Builder: Bubble Plot Updates
The bubble plot that graphs continuous model results along X and Y axis has been redesigned for clarity and more intuitive interpretation of results. The following improvements are included:
• Square shape – The overall shape of the graph is now square so that a 1:1 ratio between the X and Y axis is maintained.
• Pie chart – A pie chart has been added for addition visual clarity. It displays the percentage of records in the dataset that fall into each category of accuracy.
• Colors – The color legend used to display results have been changed to reflect more intuitive values. For example, the accurate results are shown in green, while highly overpredicted results are shown in red.

Analytics Server and Analytics Builder: Error message improved for dataset creation failure
When creating a dataset using data and metadata files attached to the request, the dataset creation fails, without a helpful message, if the CSV data contains empty rows.

Analytics Builder: For Signals, the Diff vs Avg. values are displayed incorrectly for filtered datasets
When a signals job is generated from a model based on filtered data, the Diff vs Avg. values displayed in the signals grid are calculated incorrectly against the overall average for the entire dataset. This issue has been resolved so that the Diff vs Avg. value for each record is calculated against the average of only the filtered data.

Analytics Builder: Scoring records from a REST request are not displayed correctly
When a predictive scoring job is submitted via a REST API request, the information displayed on the Model list page in Analytics Builder is incorrect. The Number of Records Scored column should reflect the number of data rows submitted in the REST request. Instead, it displays a value of 0.
This issue will be resolved in a future release.

Analytics Builder: Predictive Scoring fields cannot be added
When creating a new predictive scoring job from the Predictive Scoring tab of a model, you cannot add identifier fields from the Available Fields list. When you click Add, the field is not moved to the Fields Included in Results list.
As a work around, in ThingWorx Composer, browse to your PredictionThing and open it. Click the Services tab and use either the BatchScore service or the RealtimeScore service to create the predictive scoring job with the identifier fields you want. For procedural information about using these services to run predictive scoring, see Predictive Scoring with Confidence Models.
This issue will be resolved in a future release.

Analytics Manager: Simulation events are not compatible with Analysis Agents built on Java 11
When the Analysis Agent for your Analytics Manager is built using Java 11, simulation analysis events do not run successfully. These analysis events generate errors that can be viewed in the Analysis Agent log file. Other types of analysis events, such as discrete or cascaded events, operate successfully with a Java 11 Analysis Agent. This issue will be resolved in a future release.
