Logs with different units produce a separate value (y-axis) scale.
Archives of numerical data, however, by default show a “?” for units when charted, as shown below in Figure 5-10
. Archives of binary data show Active or Inactive and archives of multi-state data show State 0,” State 1,” State 2,” and soon.
Figure 5-10 Charts of archives containing numerical data have unknown units.
Unlike logs, archives are not associated with units or state descriptors—they are just values with timestamps. However, you can manually set both the legend descriptor and units label for an archive (or log) before charting. Click on a selected (added) archive or log, and then edit the Legend Label and Unit Axis Label fields (Figure 5-11
).
Figure 5-11 Legend Label and Unit Axis Label fields for any item can be manually set.
