Diagram and Chart Properties

Reference for diagram, chart, and drawing-layer display properties used in GeoDin site-plan and layout graphics

This page documents the display properties available for diagram and chart graphic elements used in GeoDin site-plan layouts and print graphics. For constructing site plans - scenarios, scenes, object selection, and scales - see Creating Site Plans.

Reference: Diagram Types

The following diagram types are available as graphic elements in GeoDin layouts. Select the diagram type when configuring the element properties.

Durov Diagrams

The Durov diagram is an alternative to the Piper diagram for hydrochemistry visualization. It plots major ions as percentages of milli-equivalents in two triangles, projected onto a square grid perpendicular to the third axis. The plot reveals clustering of data points with similar compositions. An ion balance calculation is performed automatically for missing ingredients.

The Durov diagram 2020 variant allows freely definable axis parameters (which must normally be converted to percent). Per triangle, sides add up to 100%. The orientation of the triangle axes and parameter labeling are freely definable. In the extended Durov diagram, additional squares are added at the bottom and right for an extra parameter in each direction with freely defined scales.

Formation Diagram (LBGR)

A classification method for high-mineralized natural waters (Valjaschko, 1960s), extended by Rechlin et al. for slightly mineralized freshwater. Distinguishes four elementary water types based on molar equivalent ratios of main ingredients (not predominating ions): Carbonate Type (unsaturated NaHCO3 water), Sulfate Sodium Type (carbonate saturated, sulfate not - dissolved Na2SO4), Sulfate Magnesium Type (carbonate and sulfate saturated with earth-alkali ions), and Chloride Type (calcium exceeds carbonate and sulfate). Requires analysis of Ca, Mg, Na, K, HCO3+CO3, SO4, Cl. The LBGR hydrogeochemical formation model (Brandenburg) distinguishes 9 formation types from precipitation through deep water-bearing layers.

Pie/Bar Chart

Displays parameters or formulas compared against each other using independently adjustable fill patterns and colors. Only positive values are drawn; use a formula such as $WAS:CL@B0,5$ to convert negative values. Each data record produces one diagram per page. Statistics can be calculated using formulas like $WAS:CL@MAX$ in the parameter list.

Circle Diagram

Plots a parameter value on a radius axis against another parameter as an angle value, displayed as a user-defined symbol. Requires defining a radius parameter, an angle parameter, and the series to be shown.

Boxplot

Graphically represents the distribution of an ordinally scaled characteristic. The box spans the middle 50% of data (25th to 75th percentile, IQR). A continuous line marks the median. Whiskers extend up to 1.5x IQR; their actual length is determined by the last data value within that limit (so whiskers may differ in length). Values beyond the whiskers are plotted individually as outliers.

Reference: Series and Calculated Lines

List Management

Where multiple elements can be defined (series, columns, calculated lines, etc.), they appear in an ordered list. Use New, Duplicate, Delete, and arrow icons to manage entries. Edit without refresh suspends recalculation during bulk edits. Double-click an entry to navigate to its properties.

Calculated Horizontal Lines

Horizontal reference lines can be added to any series in addition to curves, bars, or symbols. Available calculation types: Minimum, Mean value, Maximum, and Median (computed from measurement values), or a numeric value from Object data. Choose whether statistics use only the displayed time interval or all measurement values regardless of the visible range.

Default Line

Displays a horizontal line at a user-defined value. Select whether the line references the left or right axis.

Aggregation Preferences

An aggregation series is calculated from other series. Available types: Mean values, Sums, and Differences. For differences, values of all series from the second onward are subtracted from the first (e.g., series 3,1,2 yields value3 - value1 - value2). Enable Only values measured at the same time to restrict calculations to coincident timestamps. The Stack option enables stacked or bar display with percentage-based segments.

Measurement Frequency

Filters which datasets of a measurement series are displayed using a time-interval. Useful for distinguishing data logger records from manual measurements by defining two series with different frequency settings and line colors. Lines are automatically interrupted at frequency boundaries.

Confidence Limit

Configures confidence limit display on time series. Properties: Display name (for legend), Confidence level (0-1, typically 0.95), Upper/lower confidence level selection, Draw curve and Draw symbols toggles (with sub-node styling), and Show in legend option.

Reference: Data Filtering

Post-selection

Filters data sets from correlated data types using logical conditions. Define a Name (shown in layout interfaces) and a Condition using selection syntax. Conditions can be parameterized with placeholders: %NUMERICPARAM (numeric fields), %STRINGPARAM (text fields), %DATEPARAM (date fields). Set a Default value for parameterized conditions. Enable Make available as quick setting to expose the parameter in layout interfaces. Display selector content in layouts using $%SelectorContent:Selector_name[@format]$ - use @t for translated values or @c for key codes.

Reference: Text and Labeling

Point Labels

Displayed points can be optionally labeled by activating the Label option. The label content is defined by a labeling macro, entered directly or built using the Build icon. See Text Macros and Variable Text for macro syntax details.

Time Axis Text Formatting

Time axis labels support absolute or relative time values. Absolute format codes: d/dd (day), ddd/dddd (weekday), m/mm (month number), mmm/mmmm (month name), yy/yyyy (year), h/hh (hour), n/nn (minute), s/ss (second). Relative mode starts at 0 and labels the time difference from the start in selectable units (days, months, etc.) with configurable decimal places.

Diagram Text Positioning

Text elements can be fixed text or linked to legend labels. Position is defined in a 0,0 to 1,1 coordinate system relative to the diagram area (0,0 = lower-left, 1,1 = upper-right). Enable Use absolute coordinates of the chart axes to tie positioning to displayed parameter values. Remove text outside the chart area hides text that falls outside the diagram due to axis changes. Link to a legend label using the syntax %Leg:S=<series>,L=<label> for dynamic text.

Legend Labels

Used either within a diagram (via a text element linked with %Leg:S=,L= syntax) or in a separate legend element. Labels combine free text with variable data field names (text macro syntax). The Translation (language) setting controls dictionary retranslation; defaults to "Automatic" (uses the object type language). If no translation exists, the abbreviation is displayed directly.

Reference: Appearance Properties

Fill, Color, and Outline

Fill pattern applies to symbols with filled areas (no effect on line-only symbols). Enable Draw area transparent to show background elements through unfilled areas; disable it to hide background behind the symbol rectangle. Line type adjusts symbol contour presentation. Color is selected from the dropdown or set to "Individually" for custom colors. Line thickness can be set in mm (recommended for print consistency) or pixels (screen-only use).

Color and Transparency

The default fill pattern background color comes from the fill pattern table. Select User defined to override. Transparent fill patterns allow overlaying with visible underlying elements (not supported by all output devices). Line thickness adjustment applies only to vector fill patterns and affects print output only.

Font

Select font family, size, and style from the dropdown. Alignment uses six anchor points for precise positioning (status line shows position relative to the alignment point). Angle rotates text up to 360 degrees. Background mode: Transparent shows graphics through individual characters; Opaque crops the text with a background color (default white, customizable).
