Indicator panel
Display a color-coded label to indicate threshold values in your data.
Message path functions can be appended to the path using .@name syntax:

.@atan | Arc tangent (radians) |
.@ceil | Round up to nearest integer |
.@cos | Cosine (input in radians) |
.@degrees | Convert radians to degrees |
.@log | Natural logarithm |
.@log1p | Natural log of 1 + value |
.@log2 | Base-2 logarithm |
.@log10 | Base-10 logarithm |
.@negative | Negate the value |

.@trunc | Truncate to integer |
Operand (.@add(number), .@sub(number), .@mul(number), and more)
| Function | Description |
|---|---|
.@add(number) | Add a number |
.@sub(number) | Subtract a number |

Struct (.@rpy, .@quat)
| Function | Description |
|---|---|
.@rpy | Convert quaternion to roll/pitch/yaw (radians) |
.@quat | Convert roll/pitch/yaw to quaternion |
Not supported in this panel: Time-series functions (.@delta, .@derivative, .@timedelta). See the Plot panel for time-series modifiers (timestamp x-axis).

Comparison | How to evaluate incoming data against the 'Compare with' value ("Equal to", "Less than", "Less than or equal to", "Greater than", or "Greater than or equal to") |
Compare with | Threshold or reference value to compare against (string, number, or boolean) |
Color | Color to display when this rule matches |
Label | Text label to display when this rule matches |
