X-Y Diagrams

How to set up and configure the X-Y diagram (Measurement Value graphic element) in GeoDin layouts

The Measurement Value graphic element (X-Y diagram) plots one measurement parameter against another - for example, UU stress-strain cross-plots. It is one of two related layout elements for plotting test results; the other is the Measurement Value (Data Sequence) element for depth-vs-value plots. See Measurement Value Graphics for that one.

GeoDin also uses X-Y diagrams as graphical templates for calculating new data sequence series using formulas - the layout must contain at least one X-Y diagram element, and the selected areas within the diagram define the conditions for applying the formula.

Supported diagram types: Time Series, X-Y Diagram, Triangle, Piper diagram, Durov diagram, Pie chart, Histogram, Box plot.

Setting up an X-Y diagram

1. Add a Measurement Value graphic element to the layout (for general steps on adding elements, see Layout Editor Basics and Creating Custom Layouts).
2. Choose the diagram type from the available options (see the full list above).
3. Set the X-axis parameter and labeling.
4. Set the Y-axis parameter and labeling.
5. Add at least one Measurement Graphic Series and configure its properties.

Optional settings

• Measurement Graphic Series - name: Label identifying this series in the diagram.
• Measurement Graphic Series - data source: Set to Samples to pull from sample measurements.
• Measurement Graphic Series - object number: In a multi-object frame, specifies which measurement point in the frame the series pulls from (for example, object number 1 or 2).
• Connection line: Choose linear or spline interpolation between data points.
• Curve quality: Controls smoothness when spline is selected.
• Color: Series color.
• Symbol type: Choose from plus, circle, square, and other marker shapes.
• Symbol size: Size of the symbol markers.

Working with X-Y diagrams

Multi-object frames: A single series definition can pull from multiple measurement points using a multi-object frame. For example, a UU test layout can show undisturbed (sample 6) and remoulded (sample 8) results in the same diagram.

PSD layouts: Particle Size Distribution (PSD) layouts are pre-built and shipped with GeoDin. Customize an existing PSD layout rather than building one from scratch. See Display PSD as a Bar Chart for the full workflow.

Reference: Scale and Tag Line Properties

Scale labeling (Text)

Controls how numerical values are displayed along the scale axis:

• Label side - Place labels on the left or right side of the scale.
• Decimal places - Number of decimal places shown for numerical labels.
• Start value position - By default the start value is shown beneath the top line; it can be placed above the top line to avoid text overlaps.
• Font - Select font, size, and other typographic properties; the preview shows the current settings.

Scale view

Controls the graphic appearance of the scale itself:

• View type - Choose the preferred graphic representation; the interval width is set by the main divisions.
• Line type - Select the line type used for the scale line.
• Color - Choose from the dropdown; select "Individually" to open the full color dialog for a custom color.
• Line thickness - Set in mm (preferred for print accuracy) or pixels (screen-only graphs). When set in mm, the preview thickness may not match print output exactly.

Main help tags (tick marks)

Controls the appearance of major tick marks on the scale:

• Tag line length - Set automatically or to a fixed value.
• Tag line alignment - Default is top right; can be adjusted to centre right or bottom right.
• Color and line type - Select from dropdown or choose "Individually" for a custom color.
• Line thickness - Set in mm (preferred) or pixels.
