ScottPlot 4.1.48

NuGet packages published 2022-06-09

Plottable: Collapsed IHasAxisLimits, IHasDataValidation, and IHasLegendItems back into IPlottable, reverting a change introduced by the previous version. The intent of the original change was to promote interface segregation (e.g., colorbar has no axis limits). However, the purpose of this reversion is to maintain consistent behavior for users who implemented their own plottables implementing IPlottable and may not be aware of these new interfaces.

ScottPlot 4.1.0-beta

NuGet packages published 2020-11-29

In November, 2020 ScottPlot 4.0 branched into a permanent stable branch, and ScottPlot 4.1 began development as beta / pre-release in the main branch. ScottPlot 4.0 continues to be maintained, but modifications are aimed at small bugfixes rather than large refactoring or the addition of new features. ScottPlot 4.1 merged into the master branch in November, 2020 (#605). Improvements are focused at enhanced performance, improved thread safety, support for multiple axes, and options for data validation.
Most plotting methods are unchanged so many users will not experience any breaking changes.
Axis Limits: Axis limits are described by a AxisLimits struct (previously double[] was used)
Axis Limits: Methods which modify axis limits do not return anything (previously they returned double[])
Axis Limits: To get the latest axis limits call Plot.AxisLimits() which returns a AxisLimits object
Multiple Axes: Multiple axes are now supported! There is no change to the traditional workflow if this feature is not used.
Multiple Axes: Most axis methods accept a xAxisIndex and yAxisIndex arguments to specify which axes they will modify or return
Multiple Axes: Most plottable objects have xAxisIndex and yAxisIndex fields which specify which axes they will render on
Multiple Axes: You can enable a second Y and X axis by calling YLabel2 and XLabel2()
Multiple Axes: You can obtain an axis by calling GetXAxis(xAxisIndex) or GetYAxis(yAxisIndex), then modify its public fields to customize its behavior
Multiple Axes: The default axes (left and bottom) both use axis index 0
Multiple Axes: The secondary axes (right and top) both use axis index 1
Multiple Axes: You can create additional axes by calling Plot.AddAxis() and customize it by modifying fields of the Axis it returns.
Layout: The layout is re-calculated on every render, so it automatically adjusts to accommodate axis labels and ticks.
Layout: To achieve extra space around the data area, call Layout() to supply a minimum size for each axis.
Layout: To achieve a frameless plot where the data area fills the full figure, call LayoutFrameless()
Naming: The Plottable base class has been replaced with an IPlottable interface
Naming: Plottables have been renamed and moved into a Plottable namespace (e.g., PlottableScatter is now Plottable.ScatterPlot)
Naming: Several enums have been renamed
Settings: It is still private, but you can request it with Plot.GetSettings()
Settings: Many of its objects implement IRenderable, so their customization options are stored at the same level as their render methods.
Rendering: Bitmap objects are never stored. The Render() method will create and return a new Bitmap when called, or will render onto an existing Bitmap if it is supplied as an argument. This allows controls to manage their own performance optimization by optionally re-using a Bitmap for multiple renders.
Rendering: Drawing is achieved with using statements which respect all IDisposable drawing objects, improving thread safety and garbage collection performance.

Improved Plot.PlotFillAboveBelow() rendering of data with a non-zero baseline (#477) Thanks @el-aasi
Added Plot.PlotWaterfall() for easy creation of waterfall-style bar plots (#463, #476) Thanks @bclehmann
Axis tick labels can be displayed using notations other than base 10 by supplying Plot.Ticks() with base and prefix arguments, allowing axes that display binary (e.g., 0b100110) or hexadecimal (eg., 0x4B0D10) tick labels (#469, #457) Thanks @bclehmann
Added options to PlotBar() to facilitate customization of text displayed above bars when showValue is enabled (#483) Thanks @WillemWever
Plot objects are colored based on a pre-defined set of colors. The default colorset (category10) is the same palette of colors used by matplotlib. A new Colorset module has been created to better define this behavior, and Plot.Colorset() makes it easy to plot data using alternative colorsets. (#481)
Fixed a bug that caused instability when a population plot is zoomed-out so much that its fractional distribution curve is smaller than a single pixel (#480) Thanks @HowardWhile
Added Plot.Remove() method to make it easier to specifically remove an individual plottable after it has been plotted. Plot.Clear() is similar, but designed to remove classes of plot types rather than a specific plot object. (#479) Thanks @cstyx and @Resonanz
Signal plots can now be created with a defined minRenderIndex (in addition to the already-supported maxRenderIndex) to facilitate partial display of large arrays (#474) Thanks @bclehmann

PlotRadar() is a new plot type for creating Radar plots (also called spider plots or star plots). See cookbook and demo application for examples. (#428, #430) Thanks @bclehmann
PlotPlolygons() is a new performance-optimized variant of PlotPolygon() designed for displaying large numbers of complex shapes (#426) Thanks @StendProg
The WinForms control's Configure() now has a showCoordinatesTooltip argument to continuously display the position at the tip of the cursor as a tooltip (#410) Thanks @jcbeppler
User controls now use SHIFT (previously ALT) to lock the horizontal axis and ALT (previously SHIFT) while left-click-dragging for zoom-to-region. Holding CTRL+SHIFT while right-click-dragging now zooms evenly, without X/Y distortion. (#436) Thanks @tomwimmenhove and @StendProg
Parallel processing is now enabled by default. Performance improvements will be most noticeable on Signal plots. (#419, #245, #72)
Plot.PlotBar() now has an autoAxis argument (which defaults true) that automatically adjusts the axis limits so the base of the bar graphs touch the edge of the plot area. (#406)
OSX-specific DLLs are now only retrieved by NuGet on OSX (#433, #211, #212)
Pie charts can now be made with plt.PlotPie(). See cookbook and demo application for examples. (#421, #423) Thanks @bclehmann

Improve reliability of Plot.AxisAutoX() and Plot.AxisAutoY() (#382)
The Configure() method of FormsPlot and WpfPlot controls now have middleClickMarginX and middleClickMarginY arguments which define horizontal and vertical auto-axis margin used for middle-clicking. Setting horizontal margin to 0 is typical when plotting signals. (#383)
Plot.Grid() and Plot.Ticks() now have a snapToNearestPixel argument which controls whether these lines appear anti-aliased or not. For static images non-anti-aliased grid lines and tick marks look best, but for continuously-panning plots anti-aliased lines look better. The default behavior is to enable snapping to the nearest pixel, consistent with previous releases. (#384)
Mouse events (MouseDown, MouseMove, etc.) are now properly forwarded to the FormsPlot control (#390) Thanks @Minu476
Improved rendering of very small candlesticks and OHLCs in financial plots
Labeled plottables now display their label in the ToString() output. This is useful when viewing plottables listed in the FormsPlot settings window #391 Thanks @Minu476

NuGet packages published 2020-04-11

Plot.PlotFill() can be used to make scatter plots with shaded regions. Giving it a single pair of X/Y values (xs, ys) lets you shade beneath the curve to the baseline value (which defaults to 0). You can also give it a pair of X/Y values (xs1, ys1, xs2, ys2) and the area between the two curves will be shaded (the two curves do not need to be the same length). See cookbook for examples. (#255) Thanks @ckovamees
DataGen.Range() now has includeStop argument to include the last value in the returned array.
Tools.Pad() has been created to return a copy of a given array padded with data values on each side. (#255) Thanks @ckovamees
Seaborn style can be activated using Plot.Style(Style.Seaborn) (#339)

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 @bclehmann and @StendProg

Reduced designer mode checks to increase render speed Thanks @StendProg
Fixed cursor bug that occurred when draggable axis lines were used Thanks @Kamran
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)

ScottPlot 3.1.5

NuGet packages published 2019-10-06

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)
ScottPlot user control has a new look in designer mode. Exceptions in user controls in designer mode can crash Visual Studio, so this risk is greatly reduced by not attempting to render a ScottPlot inside Visual Studio.

ScottPlot 3.0.9

NuGet packages published 2019-08-12

New Plot Type: PlotSignalConst for extremely large arrays of data which are not expected to change after being plotted. Plots generated with this method can be much faster than PlotSignal. (#70) Thanks @StendProg
Greatly improved axis tick labels. Axis tick labels are now less likely to overlap with axis labels, and it displays very large and very small numbers well using exponential notation. (#47, #68) Thanks @Padanian
Parallel processing support for SignalPlot (#72) Thanks @StendProg
Every Plot function now returns a Plottable. When creating things like scatter plots, text, and axis lines, the returned object can now be used to update the data, position, styling, or call plot-type-specific methods.
Right-click menu now displays ScottPlot and .NET Framework version
Improved rendering of extremely zoomed-out signals
Rendering speed increased now that Format32bppPArgb is the default PixelFormat (#83) Thanks @StendProg
DataGen.NoisySin() was added
Code was tested in .NET Core 3.0 preview and compiled without error. Therefore, the next release will likely be for .NET Core 3.0 (#85, #86) Thanks @petarpetrovt
User controls now render graphs with anti-alias mode off (faster) while the mouse is being dragged. Upon release a high quality render is performed.

ScottPlot 3.0.8

NuGet packages published 2019-08-04

WPF User Control: A ScottPlotWPF user control was created to allow provide a simple mouse-interactive ScottPlot control to WPF applications. It is not as full-featured as the winforms control (it lacks a right-click menu and click-and-drag functions), but it is simple to review the code (<100 lines) and easy to use.
New plot type: plt.AxisSpan() shades a region of the graph (semi-transparency is supported)
Ticks: Vertical ticks no longer overlap with vertical axis label (#47) Thanks @bukkideme
Ticks: When axis tick labels contain very large or very small numbers, scientific notation mode is engaged
Ticks: Horizontal tick mark spacing increased to prevent overlapping
Ticks: Vertical tick mark spacing increased to be consistent with horizontal tick spacing
Plottable objects now have a SaveCSV(filename) method. Scatter and Signal plot data can be saved from the user control through the right-click menu.
Added lineStyle arguments to Scatter plots
Improved legend: ability to set location, ability to set shadow direction, markers and lines are now rendered in the legend
Improved ability to use custom fonts
Segoe UI is now the default font for all plot components

ScottPlot 3.0.7

NuGet packages published 2019-07-27

New plot type: plt.PlotStep()
New plot type plt.PlotCandlestick()
New plot type plt.PlotOHLC()
plt.MatchPadding() copies the data frame layout from one ScottPlot onto another (useful for making plots of matching size)
plt.MatchAxis() copies the axes from one ScottPlot onto another (useful for making plots match one or both axis)
plt.Legend() improvements: The location argument allows the user to place the legend at one of 9 different places on the plot. The shadowDirection argument allows the user to control if a shadow is shown and at what angle.
Custom marker shapes can be specified using the markerShape argument.

ScottPlot 3.0.6

NuGet packages published 2019-06-30

Bar plot: The plot module now has a Bar() method that lets users create various types of bar plots
Histogram: The new ScottPlot.Histogram class has tools to create and analyze histogram data (including cumulative probability)
Step plot: Scatter plots can now render as step plots. Use this feature by setting the stepDisplay argument with PlotScatter()
Manual grid spacing: Users can now manually define the grid density by setting the xSpacing and ySpacing arguments in Grid()
Draggable axis lines: Axis lines can be dragged with the mouse if the draggable argument is set to true in PlotHLine() and PlotHLine(). Draggable axis line limits can also be set by defining additional arguments.
Using the scrollwheel to zoom now zooms to the cursor position rather than the center of the plot area
ScottPlot.DataGen.RandomNormal() was created to create arbitrary amounts of normally-distributed random data
Fixed bug causing axis line color to appear incorrectly in the legend
AxisAuto() is now called automatically on the first render. This means users no longer have to call this function manually for most applications. This simplifies quickstart programs to just: instantiate plot, plot data, render (now 3 lines in total instead of 4).
Throw exceptions if scatter, bar, or signal data inputs are null (rather than failing later)

Bar graphs: New plotBar() method allow creation of bar graphs. By customizing the barWidth and xOffset arguments you can push bars together to create grouped bar graphs. Error bars can also be added with the yError argument.
Scatter plots support X and Y error bars: plotScatter() now has arguments to allow X and Y error bars with adjustable error bar line width and cap size.
Draggable axis lines: plotHLine() and plotVLine() now have a draggable argument which lets those axis lines be dragged around with the mouse (#11) Thanks @plumforest
Fixed errors caused by resizing to 0px
Fixed a capitalization inconsistency in the plotSignal argument list
axisAuto() now includes positions of axis lines (previously they were ignored)
Fixed an that caused SplitContainer splitters to freeze (#23) Thanks @bukkideme
