Click to see subtopics:On many of Harmony Enterprise’s plots (for example, analysis plot-style worksheets and the Results Viewer cross-plot), you can add a diagnostic line, which is useful for identifying and extrapolating trends in the data.
To add a diagnostic line, click the Add a Diagnostic Line icon (
) on the toolbar.
A diagnostic line requires at least one dataset or forecast. If there are multiple datasets, a popup opens where you can associate the diagnostic line with a data series. If that data series has one of its axes scaled, the diagnostic line scales with it.
If the plot’s vertical and horizontal axes are both set to use logarithmic scales (that is, if the plot is “log-log”), when you click the Add a Diagnostic Line icon, a popup opens where you can select a preset value.
Context menu
Right-clicking the diagnostic line lists these options:
- Show All Annotations — displays the x, y coordinates for both endpoints, the slope of the line, denoted by "m", as well as the formula of the line.
- Customize Line — for changing the line width and color.
- Default Slopes — for changing the slope to a preset value; this is only shown for log-log plots.
- Remove Line — deletes the line from the plot.
Line manipulation
You can manipulate the diagnostic line as follows:
- Rotate — rotates the line, keeping the center point in its original position
- Move end points — drag either end point, while the other end point stays in its original position
- Move line — drag near the center of the line to move it to another location
