Plots

GridVisualize/PlutoVista

Plotting is possible e.g. via Nodal Evaluations and the plot routines from ExtendableGrids.jl. In Pluto notebooks it is recommended to use PlutoVista.jl as an backend.

UnicodePlots

For a fast and rough peak several UnicodePlots plotters are available via an extension (ExtendableFEMBaseUnicodePlotsExt) that is loaded when UnicodePlots is available.

ExtendableFEMBase.unicode_gridplot — Function

function unicode_gridplot(
	xgrid::ExtendableGrid;
	title = "gridplot",
	resolution = (40,20),
	color = (200,200,200),
	bface_color = (255,0,0),
	CanvasType = BrailleCanvas,
	plot_based = ON_CELLS,   # or ON_FACES/ON_EDGES
	kwargs...

(via extension that requires UnicodePlots)

Plots the grid on a UnicodePlots canvas (default: BrailleCanvas) by drawing all edges in the triangulation.

ExtendableFEMBase.unicode_scalarplot — Function

function unicode_scalarplot(
	u::FEVectorBlock; 
	components = 1:get_ncomponents(u),
	abs = false,
	resolution = (30,30),
	colormap = :viridis,
	title = u.name,
	kwargs...)

(via extension that requires UnicodePlots)

Plots components of the finite element function in the FEVectorBlock u by using a lazy_interpolate! onto a coarse uniform mesh and UnicodePlots.jl lineplot or heatmap for 1D or 2D, respectively.

In 1D all components all plotted in the same lineplot, while in 2D all components are plotted in a separate heatmap.

If abs = true, only the absolute value over the components is plotted.
