• [Bug]: barchart Y axis wrongly remains labeled "proportion" after "group by" is de-selected #3289
• [Bug]: number question removes negative sign if a leading zero is typed; and removes negative and decimal if placeholding zero is typed. #3222

• [Bug]: qqplot not correct #3194

0.76.22

This update comes with improved PDF rendering and fixes student progress calculations: Since the last editor, progress values were not properly initialized when reloading a lesson after having already worked on it due to the user data not being available when attempting to recalculate the progress.

Multiple model outputs and test printouts now include the number of missing observations that were removed before the results could be calculated.

Implemented enhancements:

• links on info.json should open in new window #3088
• on-screen alert if connection to server lost #3046
• request for option for linear regression test to be added to "tests" #3045
• answers to be included in emailed "finish lesson" document, and "finish lesson" to alert and to not activate if unanswered questions #3034

0.76.21

This update adds the Tukey HSD test and extended output for the chi-square independence test. In addition, it resolves the following issues:

• Variables generated from the binning tool were not properly removed upon deletion from the list of available qualitative variables, causing select boxes in the data explorer toolbox to still list them.
• Restoration of outputs in data explorers upon reload has been improved.
• Under rare conditions, the notification system didn't properly mount, causing e.g. the "Lesson Submit" notifications prompting for a download of a lesson's answers in PDF format to not show up. This is now prevented.
• When editing plot titles of e.g. bar charts for factor variables (categorical variables with ordered categories), it was possible that multiple labels were changed at once.
• In the last release, a regression in the <Quiz /> component caused timed quizzes (i.e., when the duration property was set) to not work anymore, and the response visualizer for multiple choice questions to not display answers.

Implemented enhancements:

• Multiple Comparisons test (Tukey HSD) for ANOVA #2506
• chi-square info in contingency table #1472

0.76.20

This patch release fixes a bug in the automatic assignment of component identifiers, which caused identifiers to potentially be assigned multiple times.

0.76.19

Installing packages via npm errors in the last release. This release includes a patch solving the problem.

0.76.18

This release comes with a fix for a bug causing component identifiers to be re-generated: Instead of generating them at runtime, they are now baked in while uploading the lesson.

In addition, the release updates the internal logging of actions in preparation of the rollout of our new assessment system, which allows for fine-grained control of tracker user progress.

PDF rendering has been improved through an update of the underlying library, and several other minor bugs have been resolved (multiple dollar signs in plot labels are not interpreted as LaTeX anymore, answer formats for various question components are improved, ...)

Custom colors can now be chosen for pie charts and bar charts, and an ability to flip coordinates for violin plots has been added.

Implemented enhancements:

• request: Edit Cohort to accept space delimited, tab delimited, etc #2845
• Have ability to select custom color for legends in clustered bar charts #2324

Fixed bugs:

• [Bug]: RangeQuestion -> Answers #2903
• [Bug]: progress tab search windows not working #2880

0.76.17

This release contains bug fixes for the <IFrame /> and <Reaction /> components. Concerning new features, it allows overlaying of multiple density lines on histograms. In addition, the group functionality now allows instructors to create empty groups and/or assign students to groups who are enrolled in the course but currently not online.

Implemented enhancements:

• mathjax equivalent of \widebar{} ? #2696
• features: select more than one density overlay on histogram; and tool tip explanation #2694

Fixed bugs:

• [Bug]: applet in IFrame doesn't appear #2802

v0.76.16

This patch release refactors the display of dataset and variable descriptions for data tables, which are now combined into a single modal window. It also fixes a bug causing actions inside the context menu of links (to open in a new tab or window) to not work properly.

Implemented enhancements:

• ability to edit text of "open dataset description" button in data explorers #2765
• request "restore original dataset" button also above spreadsheet #2747

Fixed bugs:

• [Bug]: Student identifiers don't appear in select student responses #2766

v0.76.15

Among bug fixes for various components, this update comes with the following improvements:

• the <LessonSubmit /> component now has a coverage property that can be used to limit the question answers that shall be included in the generated responses PDF.
• answers in the response visualizer are now displayed in ascending order so that arriving responses do not cause the layout to change
• inactive lessons now display a button for instructors with which they can be made instantly available

This release also improves performance due to an upgrade to the latest version of the React.js user interface library, and resolves the issues listed below.

Implemented enhancements:

• request for RangeQuestion: ntries, and different feedback style #2723
• request for "create filtered data" button to be moved to top of spreadsheet #2720

Fixed bugs:

• [Bug]: new categorical variable doesn't appear in boxplot on mac chrome if space in name #2722

0.76.14

This patch release fixes several bugs and includes various improvements:

• The category labels of bar charts in the response visualizer are again correctly displayed.

• Actions are now logged when downloading source PDFs of <Sketchpad /> components.
• Grades are now automatically generated for multiple choice questions of the "Choose all that apply" variety.
• For non-skippable quizzes, the button to advance to the next question is displayed when the question has previously been answered.

Implemented enhancements:

• In NumberQuestions, the placeholder zero should auto-delete for users upon cursor plant #2343
