Allows switching between displaying the sub-charts. Just click on the tab. The standard sub-
charts that are always generated are:
a. Average (average value for the bin)
b. Standard Deviation (statistical standard deviation for the bin). A bin where the standard
deviation can’t be calculated (Number of data points less than 2) will be shown as ---.
c. Number pts: Number of data points in that bin
d. Max: the maximum value of all data points in the bin
e. Min: the minimum value of all data points in the bin
4. User charts
Use charts are sub-charts that can be filled out/edited by the user, can be pasted into or can be
the result of a chart calculation. User charts can also be filled out by LogWorks plug-ins. They can
be for example filled out by downloading the current fuel table from the ECU with the correct plug-
in for the ECU.
5. Colorizing pane
Allows colorizing the chart according to different values. See chapter xxx for details.
6. Chart/Graph pane
Shows the values of the bins of the selected sub-chart.
7. Chart bins
8. Measurement pane

measurement pane by grabbing its left border.
9. Column Headers
10. Row Headers
9.2 Selecting data to base the chart on
In the Sessions menu you can select which sessions the chart is calculated from. You can also
specify to base the chart on only the selected areas in the sessions. For details about selections,
see chapter 7.4.
For many chart calculations it is important that only relevant sections in a log are selected.
For example for an air-fuel chart used to calculate fuel maps for an ECU it is important that
transitional events like acceleration enrichment, deceleration fuel cutoff, warm-up enrichment are
NOT included in the chart creation as those would skew the averages used to measure the chart.
Use the selection tool in the Log Window, the auto search function and so on to find those areas.
Then invert the selection so that those areas are excluded.
9.2.1 Locking a chart
If you want to prevent that a chart is updated everytime you change a selection in the log/session,
you can “lock” it. This means the data in the charts is preserved, despite any changes of selection
in the originating log/session. To lock/unlock a chart, use :
