new·The score now tells you which way it movedA brain's exam only ever grows: its own material writes questions, and so does every question a real caller asked and did not get answered. The score is a percentage over that growing set, so a brain that learned more could post a smaller number — and this week three did. One of them answered two MORE questions than the week before and showed eighteen points less. Printed as a single percentage, that reads as decline to a reader and as punishment to anyone who contributes material.all news →

series types & options

9 notes, read out of this brain and free to use. Each one was extracted from a source and is re-checked against its exam.

echarts-gl 3D series types

echarts-gl adds rich 3D visualization types including three-dimensional bar chart (bar3D), three-dimensional scatter plot (scatter3D), three-dimensional flying line (lines3D), and surface plot (surface). Most visualization types can be used in multiple coordinate system components.

Series type determined by type property

Each series determines its own chart type through the `type` property.

ECharts GL components and 3D series overview

ECharts GL provides 3D rendering capabilities through WebGL. The main components include globe for spherical visualization, geo3D for geographic 3D maps, mapbox3D for Mapbox integration, and grid3D as the 3D Cartesian coordinate system. The 3D series types include scatter3D, bar3D, line3D, lines3D, map3D, surface for mesh surfaces, and polygons3D for 3D polygon visualization.

ECharts GL map visualization types

ECharts GL supports multiple types of map visualization: map3D for 3D geographic maps with elevation, and mapbox3D for integration with Mapbox tile-based mapping services.

ECharts GL surface and polygon series

ECharts GL provides surface series for rendering mesh surfaces in 3D space and polygons3D for rendering 3D polygon geometries, enabling complex 3D surface and volumetric visualizations.

Line color option with callback support

The color option sets the line color as a string or function. It defaults to adaptive color (自适应). When useColorPalette is true, the default color is fetched from the global color palette via option.color. The color can be specified as a color string or as an RGBA array, for example [1, 1, 1, 1] for pure white. When using array representation, each channel can be set to values greater than 1 to represent HDR color values.

Line opacity option

The opacity option controls the transparency of the line. It is a number type with a default value of 1.

Line width option

The width option sets the thickness of the line. It is a number type with a default value of 1.

series name option purpose

The name option is a string that specifies the series name. It is used for tooltip display, legend filtering, and to identify the corresponding series when updating data and configuration with setOption.
