• Plot.Clear() has been improved to more effectively clear plottable objects. Various overloads are provided to selectively clear or preserve certain plot types. (#275) Thanks @StendProg
• PlotBar() now supports horizontal bar graphs (#277, #315) Thanks @bonzaiferroni
• PlotBar() has been lightly refactored. Argument order has been adjusted, and additional options have been added. Error cap width is now in fractional units instead of pixel units. (#315)

Version-specific cookbook: http://swharden.com/scottplot/cookbooks/4.0.23/

• Interactive plot viewers were created to make it easy to interactively display data in a pop-up window without having to write any GUI code. Examples have been added to the ScottPlot Demo application.
  • ScottPlot.WpfPlotViewer(plt) for WPF
  • ScottPlot.FormsPlotViewer(plt) for Windows Forms
  • These can even be called from console applications
• Fixed bug that affected the ySpacing argument of Plot.Grid()
• Plot.Add() makes it easy to add a custom Plottable to the plot
• Plot.XLabels() and Plot.YLabels() can now accept just a string array (x values are auto-populated as a consecutive series of numbers).
• Aliased Plot.AxisAuto() to Plot.AutoAxis() and Plot.AutoScale() to make this function easier to locate for users who may have experience with other plot libraries. (#309) Thanks @Resonanz
• Empty plots now render grid lines, ticks, and tick labels (#313)
• New plot type: Error bars. They allow the user to define error bar size in all 4 directions by calling plt.PlotErrorBars(). (#316) Thanks @zrolfs
• Improve how dashed lines appear in the legend
• Improved minor tick positions when using log scales with logScaleX and logScaleY arguments of plt.Ticks() method
• Fixed bug that caused the center of the coordinate field to shift when calling Plot.AxisZoom()
• Grid line thickness and style (dashed, dotted, etc) can be customized with new arguments in the Plot.Grid() method

Version-specific cookbook: http://swharden.com/scottplot/cookbooks/4.0.22/

• Added support for custom horizontal axis tick rotation (#300) Thanks @SeidChr
• Added support for fixed grid spacing when using DateTime axes (#299) Thanks @SeidChr
• Updated ScottPlot icon (removed small text, styled icon after emoji)
• Improved legend font size when using display scaling (#289)

Version-specific cookbook: http://swharden.com/scottplot/cookbooks/4.0.21/

• Created new cookbook and demo applications for WinForms and WPF (#271)
• The FormsPlot.MouseMoved event now has MouseEventArgs (instead of EventArgs). The purpose of this was to make it easy to access mouse pixel coordinates via e.X and e.Y, but this change may require modifications to applications which use the old event signature.
• WpfPlot now has an AxisChanged event (like FormsPlot)
• Fixed bug that caused Plot.CoordinateFromPixelY() to return incorrect value
• Fixed bug causing cursor to show arrows when hovered over some non-draggable objects
• Improved support for WinForms and WpfPlot transparency (#286) Thanks @StendProg and @envine
• Added DataGen.Zeros() and DataGen.Ones() to generate arrays filled with values using methods familiar to numpy users.
• Added equalAxes argument to WpfPlot.Configure() (#272)
• Fixed a bug affecting the equalAxes argument in FormsPlot.Configure() (#272)
• Made all Plot.Axis methods return axis limits as double[] (previously many of them returned void)
• Added overload for Plot.PlotLine() which accepts a slope, offset, and start and end X points to make it easy to plot a linear line with known formula. Using PlotFormula() will produce the same output, but this may be simpler to use for straight lines.
• Added rSquared property to linear regression fits (#290) Thanks @Benny121221 and @StendProg
• Added Tools.ConvertPolarCoordinates() to make it easier to display polar data on ScottPlot's Cartesian axes (#298) Thanks @Benny121221
• Improved Plot.Function() (#243) Thanks @Benny121221
• Added overload for Plot.SetCulture() to let the user define number and date formatting rather than relying on pre-made cultures (#301, #236) Thanks @SeidChr

Changes to ScottPlot.Plot Module

• added CoordinateFromPixelX() and CoordinateFromPixelY() to get double precision coordinates from a pixel location. Previously only SizeF (float) precision was available. This improvement is especially useful when using DateTime axes. (#269) Thanks Chris
• added AxisScale() to adjust axis limits to set a defined scale (units per pixel) for each axis.
• added AxisEqual() to adjust axis limits to set the scale of both axes to be the same regardless of the size of each axis. (#272) Thanks @gberrante
• PlotHSpan() and PlotVSpan() now return PlottableHSpan and PlottableVSpan objects (instead of a PlottableAxSpan with a vertical property)
• PlotHLine() and PlotVLine() now return PlottableHLine and PlottableVLine objects (instead of a PlottableAxLine with a vertical property)

Miscellaneous

• ⚠️ This is the final version of ScottPlot to support .NET Framework 4.5
• Version-specific cookbook: https://swharden.com/scottplot/cookbooks/3.1.6

Minor Changes

• fully deleted the outdated ScottPlotUC
• fixed infinite zoom bug caused by calling AxisAuto() when plotting a single point (or perfectly straight horizontal or vertical line)

Minor Changes

• WPF user control improved support for display scaling (Thanks @morningkyle)
• Fixed bug that crashed on extreme zoom-outs (Thanks @morningkyle)
• WPF user control improvements (middle-click autoaxis, scrollwheel zoom)
