Tip
For more information about using the complex graph control, refer to the Using 
the Measurement Studio Windows Forms Complex Graph .NET Control section in the 
NI Measurement Studio Help.
Legend Control
Use the Measurement Studio legend control, as shown in Figure 2-1, t
display symbols and descriptions for a specific set of elements of another 
object, such as the plots or cursors of a graph. When you associate the 
legend control with another object, any changes you make to that object are 
automatically reflected in the legend. For example, if you associate the 
legend control with the plots of a graph, any changes you make in the plots 
collection editor are automatically reflected in the legend.
Tip
For more information about using the legend control, refer to the Using the 
Measurement Studio Windows Forms Legend .NET Control section in the NI Measurement 
Studio Help
.
Numeric Controls
Use the Measurement Studio numeric controls to display numerical 
information, on a Windows Forms user interface, with the look of scientific 
instruments. The numeric controls include a knob, gauge, meter, slide, 
thermometer, and tank. The following sections describe operations 
available with the controls and the classes that interface with them.
With all of the numeric controls and the classes that interface with them, 
you can perform the following operations:
Configure the scale to be linear or logarithmic and toggle the visibility 
of the scale.
Fill the scale and configure the range, color, dimensions, and style of 
the fill.
Connect to the Measurement Studio .NET numeric edit control so that 
if you change the value of one control, it changes the value of the other 
control.
