• Autorecovery was exhibiting strange behavior around recovering unsaved worksheets
• The Date/time label positions were inconsistent for Contour Plots
• Crash after deleting an axis and then undoing the deletion
• Crash saving file after reloading data
• Crash when adding a XY Contour Data plot to existing plot
• Crash when exporting grid data to restricted file location via automation

Fixes:

• Hang when cutting/pasting data used in fit calculations after statistics are inserted in plot

• Artifacts when the worksheet is created while opening Grapher
• Log base 10 axes had errant artifacts displayed when custom limits were defined
• Internal Error when inserting statistics for fit with missing/no data

• Crash when manually moving axis labels

• Crash when opening file

• Crash when opening file containing Rose charts
• Crash when loading symbol table for Polar plots
• Crash closing a file without saving

Grapher 17.1.408  (01 December 2020)

New features and Improvements:

• Auto-recovery (restore backup files after crash)
• Notifications pane has been added
• Convert between 2D scatter plots to 2D class scatter plots
• Improved selection for plots (hidden plots cannot be selected)
• Criteria filter dialog clearly shows what Null Criteria and Column Criteria do (include vs. exclude)
• Add Plot:
  • Improved functionality around adding a plot to a graph from the ribbon
  • Select Plot Type dialog now includes all possible plot variations
• Legend:
  • Control size of samples/symbols in legend for individual entries
  • Show line properties in legend for added class plots

• Crash when editing Graph properties
• Crash adding 3D graph types
• Crash closing document after copying and pasting Surface Data map (with legend and color scale)
• Crash displaying certain labels on box plots
• Crash running scripts that add Spline fit or LOESS fit

• Crash when drawing title text on plot with a single point
• Crash when duplicating axis on Contour XY Data Map
• Fit Curve: Statistics R and R^2 are incorrect due to error in RSS and RGSS calculation
• R^2 value reported incorrectly for power fit of log(10) data
• Polar Plot: No longer overwrites angle axis line properties with grid line properties
• General code improvements
