Performs advanced settings for statistical charts in current statistical thematic maps. All settings in this tab will be reflected in real-time on the current statistical thematic map (WYSIWYG).

1. "Options" Area: Adjusts and controls the display of statistical charts in thematic maps.
   • Flow: When checked, thematic maps will dynamically adjust rendering positions during map navigation to ensure full visibility. Avoid using partial refresh when flow effect is enabled (SuperMap iDesktopX does not support partial refresh).
   • No Overlap: Enables automatic adjustment of chart positions to prevent overlapping.
   • Show Negative: Displays statistical charts for features with negative attribute values.
   • Scale With Map: Adjusts chart sizes proportionally with map zoom level. When unchecked, charts maintain fixed display sizes.
   • Show Leader Line: Displays connecting lines between offset charts and their features. Requires "Flow" to be enabled. Click "Line Style" to customize connector appearance.
2. Global Statistics Values: When enabled, charts share uniform scaling based on global value ranges (left image). Disabled mode uses independent scaling per feature (right image).

   When disabled, charts use individual scaling ranges without proportional relationships between values.

3. "Visible Size Range" Area: Controls chart size baselines (max/min values). Units match map coordinates when "Scale With Map Zoom" is enabled, otherwise in 0.01mm.
   • Start Expression: Use field values or numerical inputs to control base chart sizes.
   • Maximum Display Value: Sets upper size limit. For pie/rose/donut charts, diameter equals 1/4 of max value. Column/area charts use 1/4 value as height.
   • Minimum Display Value: Sets lower size limit, following same 1/4 calculation rules as maximum value.
4. "Offset Settings" Area: Adjusts chart anchor point positions relative to features.
   • Offset X: Horizontal displacement value or field selection.
   • Offset Y: Vertical displacement value or field selection.
   • Offset Unit: Choose between map units or 0.1mm measurement.
5. "Statistics Chart Labels" Area: Configures chart value annotations.
   • Label Format: 5 preset formats: Percentage, Actual Value, Title, Title+Percentage, Title+Value.
   • Label Style: Customizes annotation text style. See: Modify Uniform Label Thematic Map Style.
6. "Axes" Area: Configures coordinate axes display for applicable chart types (area, step, line, point, bar charts).
   • Axis Color: Sets coordinate axis color.
   • Label Mode: 4 display options: None, X Only, Y Only, Both.
   • Label Style: Customizes axis text style. See: Modify Uniform Label Thematic Map Style.
   • Axis Grid: Toggles grid line display.
7. Bar Styles:
   • Column Width Coefficient: Controls bar width (0 to max width). Applies to 2D/3D bar charts.
   • Column Spacing Coefficient: Adjusts spacing between adjacent bars.
8. Rose and Pie Styles:
   • Start Angle: Initial rotation angle (0°=horizontal right). Affects pie/rose charts.
   • Rose Angle: Sector angle for rose chart segments. Values ≥360° create equal divisions.
9. Settings take effect immediately unless "Enable Instant Refresh" is disabled. Use "Apply" button for manual refresh when real-time update is disabled.

Notes

1. Thematic map configurations can be saved as templates for reuse. See: Save to Thematic Map Template Library.
2. Pre-saved templates appear in dropdown menu when creating new thematic maps.
