Plotting Post Value Procedures

Plotting a Single Analyte

1. Plot 2d Data -> Post Values

2. Select Analyte

3. Filter Locations and Date Range

4. Transform Data (min., max. etc.)

5. Select Standard

Optimize Location Positioning

Plotting a Single Analyte

• Use Optimize Location to Automatically Position Callout Boxes

• Slows Redraw

• Before saving document, advisable to unselect Optimize Location.
