Visualization

viz(object; [options])

Visualize Meshes.jl object (e.g., mesh, geometry) with options such as color and alpha values for transparency. All available options will be documented below upon loading a Makie.jl backend.

Examples

Different coloring methods (vertex vs. element):

# vertex coloring (i.e. linear interpolation)
viz(mesh, color = 1:nvertices(mesh))

# element coloring (i.e. discrete colors)
viz(mesh, color = 1:nelements(mesh))

Different strategies to show the boundary of geometries (showsegments vs. boundary):

# visualize boundary with showsegments
viz(polygon, showsegments = true)

# visualize boundary with separate call
viz(polygon)
viz!(boundary(polygon))

Notes

This function will only work in the presence of a Makie.jl backend via package extensions in Julia v1.9 or later versions of the language.

Values passed to the color option can be of any type, as long as they can be converted to colors by the colorfy function from the Colorfy.jl package.

For Mesh subtypes, the length of the vector of colors determines if the colors should be assigned to vertices or to elements.

Viz

Plot type

The plot type alias for the viz function is Viz.

Attributes

alpha = 1.0 — scalar or vector of transparency values in [0, 1]

color = :slategray3 — scalar or vector of colors for geometries

colormap = :viridis — color scheme (a.k.a. map) from ColorSchemes.jl

colorrange = :extrema — minimum and maximum color values or symbol

pointcolor = :gray30 — color of points

pointmarker = :circle — marker of points

pointsize = 4 — size of points

segmentcolor = :gray30 — color of segments

segmentsize = 1.5 — width of segments

showpoints = false — visualize points

showsegments = false — visualize segments

viz!(object; [options])

Visualize Meshes.jl object (e.g., mesh, geometry) in an existing scene with options forwarded to viz.

viz! is the mutating variant of plotting function viz. Check the docstring for viz for further information.

viewer(geotable; kwargs...)

Basic scientific viewer for geospatial table geotable.

Aesthetic options are forwarded via kwargs to the Meshes.viz recipe.

Notes

This function will only work in the presence of a Makie.jl backend via package extensions in Julia v1.9 or later versions of the language.

cbar(fig[row, col], values; colormap=:viridis, colorrange=:extrema)

Add a colorbar to fig[row, col] for the given values and options for the colorfy function from the Colorfy.jl package.

Notes

This function will only work in the presence of a Makie.jl backend via package extensions in Julia v1.9 or later versions of the language.

hscatter(geotable, vars; [options])

h-scatter plot for all variables vars stored in the geotable. Optionally, specify the options documented below.

Options

• lag - lag distance in length units (default to 0.0u"m")
• tol - tolerance for lag distance (default to 0.1u"m")
• distance - distance from Distances.jl (default to Euclidean())
• nmax - maximum number of samples (default to 4000)
• size - size of points (default to 2)
• color - color of points (default to :black)
• alpha - transparency of points (default to 1.0)
• rcolor - color of regression line (default to :salmon)
• icolor - color of identity line (default to :black)
• ccolor - color of center lines (default to :teal)

Examples

# h-scatter of z vs. z at lag 1.0
hscatter(geotable, "z", lag=1.0)

# h-scatter of z vs. w at lag 2.0
hscatter(geotable, ["z", "w"], lag=2.0)

Notes

This function will only work in the presence of a Makie.jl backend via package extensions in Julia v1.9 or later versions of the language.
