Lines
A simple line plot of the 3 columns.
plot(rand(100,3))
Functions
Plot multiple functions.
plot(0:0.01:4π,[sin,cos])
You can also call it with plot(f, xmin, xmax).
plot([sin,cos],0,4π)
Or make a parametric plot with plot(fx, fy, umin, umax).
plot(sin,(x->begin # /home/tom/.julia/v0.4/Plots/docs/example_generation.jl, line 33:
sin(2x)
end),0,2π)
Global
Change the guides/background without a separate call.
plot(rand(10); title="TITLE",xlabel="XLABEL",ylabel="YLABEL",background_color=RGB(0.5,0.5,0.5))
Two-axis
Use the axis or axiss arguments.
Note: This is only supported with Qwt right now
plot(Vector[randn(100),randn(100) * 100]; axiss=[:left,:right],ylabel="LEFT",yrightlabel="RIGHT")
Vectors w/ pluralized args
Plot multiple series with different numbers of points. Mix arguments that apply to all series (singular... see marker) with arguments unique to each series (pluralized... see colors).
plot(Vector[rand(10),rand(20)]; marker=:ellipse,markersize=8,colors=[:red,:blue])
Build plot in pieces
Start with a base plot...
plot(rand(100) / 3; reg=true,fillto=0)
and add to it later.
scatter!(rand(100); markersize=6,color=:blue)
Heatmaps
heatmap(randn(10000),randn(10000); nbins=100)
Lots of line types
Options: (:line, :step, :stepinverted, :sticks, :dots, :none, :heatmap, :hexbin, :hist, :bar)
Note: some may not work with all backends
plot(rand(20,4); linetypes=[:line,:step,:sticks,:dots],labels=["line","step","sticks","dots"])
Lots of line styles
Options: (:solid, :dash, :dot, :dashdot, :dashdotdot)
Note: some may not work with all backends
plot(rand(20,5); linestyles=[:solid,:dash,:dot,:dashdot,:dashdotdot],labels=["solid","dash","dot","dashdot","dashdotdot"])
Lots of marker types
markers = supportedMarkers()
plot([fill(i,10) for i = 1:length(markers)]; marker=:auto,labels=map(string,markers),markersize=10)
Bar
x is the midpoint of the bar. (todo: allow passing of edges instead of midpoints)
bar(randn(1000))
Histogram
note: fillto isn't supported on all backends
histogram(randn(1000); nbins=50,fillto=20)
