<H2><A NAME="7_10">7.10 Handling date/time scales</A></H2>
|
|
|
29 |
<P> With date/time scale we refer to the plotting of data where the
|
|
|
30 |
independent variable (X-axis) de-nominates a time value. This could for
|
|
|
31 |
example be the temperature measured in intervals during a day.</P>
|
|
|
32 |
<P> From version 1.18 and onwards there are two principal ways of
|
|
|
33 |
handling date/time scales. The manual way and fully automatic using the
|
|
|
34 |
special "dat" scale. For most cases the automatic "dat" scale is the
|
|
|
35 |
preferred choice but in rare circumstances it might be more appropriate
|
|
|
36 |
to use the manual way since it gives slightly more control (but not
|
|
|
37 |
that much) of the overall handling of scales.</P>
|
|
|
38 |
<P> To be able to use a date/time scale at all we will assume that the
|
|
|
39 |
data points are represented by both an X coordinate (time-value) and a
|
|
|
40 |
Y-value (anything else wouldn't make sense).</P>
|
|
|
41 |
<P> We first start by describing the use of the "dat" scale.</P>
