The Instrumentation.NET Pro contains 31 additional .NET components, with advanced features not included with the Instrumentation.NET Standard. Spectrum Display The Spectrum Display Control is a spectrum display with optional peak and peak decay support. You can set the number of bars, and set each bar independantly at runtime. Bar values displayed at design-time are for illustrative purposes only to aide in development of your application. You will need to use the clear method or initialize all bar elements at runtime to clear out these initial/illustrative values. Sliding Compass The Sliding Compass Control is a moving graphical compass with a linear and circular representation of the data (360 degree circular scale). One static pointer refers to the position of the moving scale and an unlimited number of dynamic pointers can refers to a other/secondary positions on the moving scale. The Sliding Compass also has Shadow effects (ScaleShadowColor, ScaleShadowEnabled, ScaleBackgroundColor) that give the Sliding Compass a three dimensional look. Compass The Compass control is used to display a graphical representation of a compass. Use the Direction property to change the direction the compass is pointing to. To also show the numerical value that the compass is pointing to in the center of the control, set the ShowDirectionDisplay property to True. The .NET compass offers an unlimited number of compass pointers making this control a multi-compass control too! LED Matrix The LED Matrix is a grid of LED elements. The advantage of using the LED Matrix component instead of placing individual LED's on your development form is that only one window handle is needed for the entire control. Consequently, the painting speed is much faster than having each element paint itself. Pie Chart The Pie Chart control is used to display a graphical bar representation of item percentages. Use the property editor to add or remove items and change their property's at design time. At runtime, use Item.Add, Item.Remove, Item.Cleart, and Item.Count to add or remove items, and change the Items Text, Color, and Value at any time. The legend value and percentage columns can be individually hidden at any time too. Percent Bar The Percent Bar control is used to display a graphical bar representation of item percentages. Use the property editor to add or remove items and change their property's at design time. At runtime, use Item.Add, Remove, Clear and/or Count to add or remove items etc. You can change the Items Title, Color, and Value at any time. The legend value and percentage columns can be individually hidden at any time too. Object Canvas The Object Canvas control is a basic canvas with an interface for adding persistent objects at runtime (Painting Persistence Only). All painting is handled automatically and is double-buffered to prevent flickering at run-time. The coordinate system is based on the Cartesian coordinate system with (0,0) corresponding to the center of the component. The X & Y range is set using the DisplayRangeX and DisplayRangeY property's. Drawing objects can be added to the canvas (Ellipse, Rectangle, Line, Pie, Polygon, Arc, Image, Textbox and Text). There is no limitation to the number or types of basic objects that can be added. When one of the drawing objects is added, all properties of the object not specified in the parameters of the add method's are set according to the Default property settings. Once an object is added, any property of the object can be modified at any time. Rotation Display The Rotation Display control is used for rotating a bitmap in real-time. The lower left pixel of the bitmap is used for the transparent color. To specify the angle of rotation , set the Rotation property. The performance depends on the number of rotations per second and the size of the bitmap. The performance is not impacted by the size of the control, only the portion where the bitmap is displayed is actually rotated. To increase performance, decrease the bitmap size or decrease the rate at which the Rotation property is changed. LED Arrow The LED Arror control is an Arrow shaped LED with a None, Raised, or Lowered BevelStyle. Define arrows with a single or dual-headed. Switch Rockers The Switch Rocker control is a binary switch with a rocker graphical representation . The control uses the space key for keyboard control. The Switch Rocker 3-way control is a momentary up and down switch. It has events and property's built to simplify the implementation of single axis control. Use the ValueChanged event to respond to changes. Use the Increment property to specify the amount the Value property is changed on each click or repeat event. Switch Lever The Switch Lever control is a binary switch with a lever graphical representation. The control uses the space key for keyboard control. Use the ValueChanged event to respond to changes in the Value property. Switch Quad The Switch Quad control can be used for any type of 2-axis control. There are independent events for each switch. This control has events and properties built-in to simplify the implementation of X-Y control. For Y-Axis control, use the ValueXChanged event along with the ValueY and IncrementY properties. For X-Axis control, use the ValueXChanged event along with the ValueX and IncrementX properties. By default, the repeat feature is enabled and is configured with the RepeatInitialDelay and RepeatInterval properties. These are customizable and can be disabled. The control supports the 4 arrows keys on the keyboard for keyboard control, which can be disabled at any point. Phone Pad The Phone Pad Control is a simple numeric keypad control with mouse control support. Input is processed in your application by using the ButtonClick event. Panel The Panel control is a basic panel that can have child controls embedded within it. Pipe The Pipe Control is used to display a graphical representation of a pipe. Supports built-in flow animation, with selectable flow indicators, flow rate, and flow direction. Motor The Motor control is used to display a graphical representation of a stationary or moving motor or pump. Tank The iTank control is a tank that supports a double-value indicator. Valve The Valve component supports an opened and closed position.
