Graph cannot be plotted.
Because of no data
A graph cannot be plotted because
the currently displayed window
contains no data.
Perform graph plotting only when
data is available in the window.
Graph cannot be plotted.
Illegal data
No graph was plotted because
the graph range to plot contained
inappropriate data.
This message also appears if
there is no data in the graph range.
Check if data in the set graph
range is appropriate.
Also check if there is data in the
graph range.
Selection error
Data required is not
selected.
Some of the data required to plot
the graph have not been selected.
Check that the complete data
required to plot the graph has
been provided.
Selection error
The maximum number of
peaks that can be selected
at one time is 6.
More than 6 peaks have been
selected.
The maximum number of peaks
that can be displayed on a graph
at one time is 6.
Select six or less peaks.
Selection error
Start time was set to a time
later than the end time.
The start time was set to a time
later than the end time when
setting up the time axis (in Manual
mode).
Set the start time to a time earlier
than the end time.
Graph cannot be created /
plotted.
For logarithmic graphs,
axes can not be set at zero
or negative values.
Zero or negative values were
set as the minimum or maximum
values when setting up logarithmic
axes (in Manual mode).
Logarithmic axes cannot display
zero or negative values. When
