Version 23.1. Released 09/04/2014

New Features:

  1. Added Animation support (see screenshot) - new class CBCGPAnimationManager wraps functionality of Windows IUIAnimationManager interface. Using this new class, developer can add animation support in few lines of code: just derive any class from CBCGPAnimationManager, call StartAnimation and override OnAnimationValueChanged virtual method. The following animation types are supported:
    1. Legacy: timer-based animation. If application is launched under the OS where Animation Manager is not supported (for example Windows XP or Windows Vista without SP1), CBCGPAnimationManager will automatically use this animation type.
    2. Accelerate/Decelerate
    3. Cubic
    4. Linear
    5. Smooth Stop
    6. Parabolic from Acceleration
    The animation support was added to the following product components:
    1. Chart control (series appearance).
    2. Gauges (smooth pointer moving).
    3. Page transition manager (used in the property sheet, ribbon backstage view in custom page containers).
    4. WinUI Tiles
    Please run a new sample AnimationManagerDemo to study how to implement your own animation.

      • Data Bars (see screenshot ). The length of the data bar represents the value in the cell. Call 'CBCGPGridItem::SetDataBar' new method to specify the data bar length (in percentage). By default, the data bars appearance is provided by the Grid color theme, but you can change it by calling a new method 'CBCGPGridCtrl::SetCustomDataBarColors'. A new method 'OnDrawGridDataBar' has been added to CBCGPVisualManager class, so you can customize Data Bars appearance in your own visual manager.
      • Color Scales (see screenshot ). Displays 2 or 3 color gradients in a range of cells. The shade of the color represents the value in the cell. Call 'CBCGPGridItem::SetDataColorScale' new method to specify the color shade (in percentage). By default, the colors are provided by the Grid color theme, but you can customize them by specifying the following new members of CBCGPGridColors:
        • m_clrScaleLow: the color of the lowest value.
        • m_clrScaleHigh: the color of the highest value.

        In addition, you can override GetGridColorScaleBaseColors method in your CBCGPVisualManager-derived class.
      • Icon Sets (see screenshot ). Displays an icon from the icon set in each cell. Each icon represents the value in the cell. Call 'CBCGPGridItem::SetDataIcon' new method to specify the icon (in percentage). By default, the Grid displays icons from the default set (5 arrows), but you can specify the icons set by calling a new method 'CBCGPGridCtrl::SetCustomDataIconSet'.
    2. Added Sparkline grid cells (see screenshot). A new class CBCGPGridSparklineItem implements a sparklines grid cell - using this class you can easily add charts to your grid. The main advantages of this feature are:

Version 17.0. Released 01/23/2012

New features:

  1. Added the long awaited Diagram Control (see screenshot), which implements the following features:
    • Ability to add unlimited number of diagram shapes and connectors.
    • Various predefined diagram blocks, including circles, triangles, boxes, rounded boxes, parallelograms, trapezoids, stars and clouds.
    • Table diagram block.
    • Text labels inside diagram blocks.
    • Smart straight and curved diagram connectors with 5 types of customizable arrows.
    • Interactive diagram editing.
    • Ability to save and load diagram to/from XML.
    • Copy diagram image to the Clipboard.
    • Save diagram image to a file.
    • Please run the new BCGPDiagramDemo example to see the new control in action.
  2. Chart Control implements new and updates existing features:
    • Axis scale breaks (see screenshot). Call CBCGPChartAxis::EnableScaleBreaks to enable this feature for an axis. Scale breaks can be generated automatically or added manually. See the updated BCGPChartExample | Advanced Features | Scale Breaks for more info.
    • Added new chart category - Histogram. Use the new BCGPChartHistogram category and CBCGPChartHistogramSeries class to create series of this type.
    • Implemented two new technical indicators for Stock charts (see screenshot): Bollinger Bands and MACD. Use CBCGPChartBollingerBandsFormula and CBCGPChartMACDFormula classes to add these indicators to Stock charts.
    • Stock charts are optimized to handle very large data. Call CBCGPChartStockSeries::AddData and pass a CArray of CBCGPChartStockData objects to quickly initialize a stock series with market data.
    • Now stock series are working in "index mode" mode by default. It means that data points are accessed by index, but X axis displays labels according to date stored in the X component of data point. Important note. Do not call CBCGPChartAxisX::SetFixedDisplayRange with date/time values, use data point indexes instead.
    • Now you can create virtual stock series by overriding only three methods: IsOptimizedLongDataMode (should return TRUE), GetDataPointCount (should return the total number of data points in a stock series) and GetStockDataAt , which should return the data obtained from external source.
    • Line, Area, Column, Bar and Histogram series can handle very large volumes by trading off the ability to customize individual data point properties. Call CBCGPChartSeries::AddDataPointsOptimized or CBCGPChartVisualObject::AddDataPointsOptimized with array of double values to add a batch of data points. Take a look at BCGPChartDemo | Large Volume Charts | Huge Data to see this feature in action.
    • CBCGPChartAdvancedFormula output series now takes advantage of "optimized long data" feature, which allows to increate performance and reduce memory consumption. Set CBCGPChartAdvancedFormula::m_bUseLongData to FALSE before creation of output series to use "regular" data points.
    • Added support for tooltips (see screenshot). Call CBCGPChartCtrl::EanbleTooltip to enable tooltips for a chart control. You can override CBCGPChartSeries::OnGetDataPointTooltip to customize tooltip text for a specific data point. You can override CBCGPChartVisualObject::OnGetToolTip to customize a tooltip displayed at specified client coordinates.
    • You can customize series fill opacity by calling BCGPChartFormatSeries::SetSeriesFillOpacity .
    • Added new notifications about axis zoom and scroll actions: chart control's owners will receive BCGM_ON_CHART_AXIS_ZOOMED and BCGM_ON_CHART_AXIS_SCROLLED messages. Also you can override OnAxisZoomed and OnAxisScrolled overrides in CBCGPChartVisualObject.
    • CBCGPChartAxis has two new members m_szMaxFixedLabelSize and m_strMaxDisplayedLabel . The first member allows to specify maximal axis label size (in pixels), which won't be overridden by internal calculations. The second allows to specify a label whose size will be used as maximal label size.
    • Output series type encapsulated in CBCGPChartAdvancedFormula can be customized by overriding of GetOutputSeriesType and GetOutputSeriesCategory methods.
    • CBCGPChartObject has a new coordinate mode CM_PIXEL_FIXED_SIZE. Now you can add objects of fixed size to the diagram area and specify object size and position in pixels.
    • CBCGPChartLongSeries has a new method GetNearestScreenPoint, which calculates position for interactive markers.
    • Chart View correctly handles Windows 7 task bar interaction.
    • Pan mode correctly scrolls different series displayed on different axes.
