Select Levey-Jennings Chart Options

Note: The options selected for a Levey-Jennings Chart also apply to the Multi-LJ Chart.

1. Click the Charts tab.
2. Click Options.
3. Click Levey-Jennings.
4. Select the Days on charts option.
   • The default is 60 days.
   • Select a number from 1 to 90.
5. Select the X-axis type:
   • Date

     The X-axis shows a vertical column for each day. Each data point collected during that day appears in this column so the individual data points appear to be stacked.

     Selecting the Include point representing mean of data points for the day check box adds a large point representing the daily mean and shows the individual data points as smaller points.

   • Sequence
     Each data point appears in its own column.

     Note: Selecting the Sequence option makes the Include point representing mean of data points for the day check box unavailable.

6. Select the Action check box to include an action (if any) in the Levey-Jennings Chart header. The action number and description appear in the chart header and at the top of the chart corresponding to the date of the action.

   

7. Each control level has a default symbol to represent the level's data. To change the default symbol, select a Symbol for each Level point from the list.

    Tip: The different symbols help visually distinguish the levels when printing in black and white. An arrow represents data points that are off the scale, regardless of the level symbol selected.

8. Select the Size for each Symbol.
   • The default is 6.
   • Select a size from 1 to 10 (pixels).
9. Select the Fill check box to select a fill color for each level symbol.

   Tip: The different colors help visually distinguish the levels when viewing the chart on a color monitor.

10. Click (ellipsis button) for the fill and select the background color from the palette.

    Important: UnityWeb™ shows data points violating a statistical process control (SPC) rule with a status of "warning" in orange and data points violating a rule with a status of "reject" in red. Therefore, Bio‑Rad recommends not using orange or red for fill colors as it could make these data points difficult to see.

11. Select the Connect line check box to draw a line connecting the data points on the chart.
12. Repeat steps 7 through 11 as needed for each level.

    Note: The line connects the mean of the points for the day and only appears if the Include point representing mean of data points for the day check box is selected.

13. Click Save.

    Note: Click Default to return to the default settings.
