Detailed Description

Stores the settings for rendering a single diagram.

QgsDiagramSettings stores the settings related to rendering the individual diagrams themselves, while QgsDiagramLayerSettings stores settings which control how ALL diagrams within a layer are rendered.

◆ maximumScale

double QgsDiagramSettings::maximumScale = 0

The maximum map scale (i.e.

most "zoomed in" scale) at which the diagrams will be visible. The scale value indicates the scale denominator, e.g. 1000.0 for a 1:1000 map. A scale of 0 indicates no maximum scale visibility.

See also: minimumScale

Definition at line 457 of file qgsdiagramrenderer.h.

◆ minimumScale

double QgsDiagramSettings::minimumScale = 0

The minimum map scale (i.e.

most "zoomed out" scale) at which the diagrams will be visible. The scale value indicates the scale denominator, e.g. 1000.0 for a 1:1000 map. A scale of 0 indicates no minimum scale visibility.

Definition at line 465 of file qgsdiagramrenderer.h.
