Parameters
Is the name of a 1D or 2D dataset.
Is the type of the coordinate:
| Value | Meaning |
|---|---|
| x | x coordinate |
| y | y coordinate |
| x_pos | x coordinate: Text object will be moved to this position. |

If the string :date is added to the type name the value will be formatted as a date/time value.
Data point index. The Index starts with 1. If a negative index is specified, the counting starts at the last data point. Example: To read the value of the second last point index is -2.
Specifies the number format. The default format is %g. Example: %.3lf will print the values with 3 decimal places. For a complete description see printf. In field functions commas are not allowed inside the format string. If the string :date is added to the type name the value will be formatted as a date/time value. To format the string the DT_Format function is used.
Example
y[1]: @f{xyvalue(Data 1, y, 1)}
y[last]: @f{xyvalue(Data 1, y, -1, %.2lf)}
Date: @f{xyvalue(Data2, x:date, 1, %c)}
Output:
y[1]: 123.2
y[last]:= 123.19
Date: 1.11.2007 00:00:00
