XControls Components

Analog components are a collection of 12 ActiveX components intended for the display or input of analog and real-number based data. Each component is designed for high-speed and robustness. All components include double, triple, or quadruple-buffering to improve display performance with a low impact on processor usage. These components are included in the Instrument Pack and Professional Pack Products.


Knob

The Knob control is a 3D knob which supports both mouse and keyboard control. To setup as a multi-turn Knob, set the RotationMaxDegrees property to multiples of 360 degrees.

Seven Segment Analog

The Seven Segment Analog is a seven-segment display used for displaying analog (real number) values. You can specify the total number of display digits and the number of precision digits. If the Value overflows the display in the positive direction, then up arrows will be shown. If the Value overflows the display in the negative direction, then down arrows will be shown.

Label

iLabelX is a windowed control that displays text on a form. This text can be used to label another control, and can be placed on top of or below other controls (which the standard Windows label cannot do). The iLabelX is similar to a standard Windows label, but has additional features such as BorderStyle and Shadow properties that provide a 3D, raised, or sunken effect (ShadowColor, ShadowShow, ShadowXOffset, ShadowYOffset).

Strip Chart

The Strip Chart control is a basic real-time strip chart with cursor, scroll, zoom, and zoom-box tools. To add data, you must add a time index first using the AddIndexTime method passing the new X-Axis time value. Use the return data index from AddIndexTime to then add data for each channel using the SetChannelData procedure. To improve performance, use the BeginUpdate and EndUpdate to prevent repaints every time a piece of data is added.

The user can use the cursor, scroll, zoom, and zoom-box tools while data is being plotted. The display will not scroll or auto-scale while the tools are being used. When the user switches out of the plot mode and into one of the tool modes, all X-Axis and Y-Axis settings are stored. When the user returns the mode back to plot, the previous X-Axis and Y-Axis settings are restored.
