Bind a control to a variable

A control is bound to a variable by drag & drop: grab the variable in the Solution Explorer and drop it on a control on the workspace. Only variables assigned to a protocol can be bound (see Add a variable).

The behavior depends on the control type:

• Gauge, Single-Signal, and Matrix display one variable — dropping another variable replaces the original one.
• Graph, XY Graph, and Watch Table display multiple variables — every drop adds another series or row.

Each control also accepts only compatible variable types — an incompatible variable cannot be dropped on it:

Bindings are saved with the project and restored automatically when it is opened.

Which control for what

Each control has its own chapter with a detailed description of its settings:

• Graph — signal time course with multiple series and vertical axes,
• XY Graph — one signal against another: hysteresis, Lissajous, characteristic curves,
• Gauge — an instantaneous value as a radial or linear indicator with zones,
• Single-Signal — a single value with a caption and unit, it can also write to the device,
• Watch Table — a table of several variables, it can also write to the device per row,
• Matrix — an array, curve, or map from a Matrix variable, including cell calibration.

All controls have a configurable refresh period (Refresh time, default 250 ms) so they do not overload the UI with fast data.
