- NOTE({valuexpr,}xexpr,yexpr); Put text label and optional value on plot
-
- The NOTE procedure causes DAN to output a text string to the graphics
- area of a plot. The text may optionally be followed by a specified
- numeric value. The text is taken from the most recently processed TEXT
- statement. The lower left corner of the first character in the text is
- output starting at the coordinates given by 'xexpr' and 'yexpr'. These
- coordinates are given with respect to the current scaling values, hence
- the YMIN, YMAX, etc. values must have been set before the NOTE
- statement is executed.
-
- A text only message is output if only the x and y coordinates are
- specified in the NOTE statement. That is, if the NOTE statement only
- contains two parameters then they are assumed to be x and y
- coordinates, and a value is not appended to the text string.
- +
- If any of the expressions in the statement contains a variable then the
- NOTE statement will cause an implicit loop to be executed with multiple
- notes being output; one for each step in the implicit loop. This feature
- can be used to label multiple points along a trace or maintain a running
- value that is updated as the trace is output.
-
- This procedure may be used for annotating graphs with calculated values.
- The CONNECT procedure may be used to visually attach a NOTE to a point on
- a plot.
