Legends
Legend example using the classic mode. In this example we show the two ways in which the legend
option can be used. First one is only legend="Bla"
and in the second one, argument as a NamedTuple, we set more detailed instructions about the legend.
using GMT
x = linspace(0,2π,50);
lines(x, sin.(x), ls="lineDiamond", legend="sin(x)", grid=(pen="gray90",), theme=("A2"), xaxis=(annot="pi2",))
lines!(x, cos.(x), ls="linesquare", legend=(label="cos(x)", pos=:MiddleCenter, box=:none), mc=:red, show=true)
With different page and frame colors filling
We can set the frame filling color in any of the frame
, xaxis
or yaxis
option, and the frame and page colors can be different. Use this fact to show a equation in a legend.
using GMT
x = 1:10
lines(x, x.^2, limits=(0,10,0,100), linewidth=2, linestyle=".-", pagecolor="#D0DFE6FF",
xaxis=(xlabel="x", bgcolor=:lightgray), ylabel="x@+2@+", legend=(label="x@+2@+", pos=:LT), show=true)
Apples & Oranges
The legend
method can automatically create a legend for symbols plotted using plot. Legend entries are only created when the legend
option is used (but see also the legend module.)
using GMT
gmtbegin()
plot("@Table_5_11.txt", region=[0., 7.2, 3, 7.2], figscale=2, pen=(1.5, :gray),
legend="Branch lines", frame=:a)
plot("@Table_5_11.txt", marker=:circle, markersize=0.35, markercolor="lightgreen",
markerline="faint", legend="Apples")
plot("@Table_5_11.txt", marker=:triangle, ms=0.35, fill="orange", legend="Oranges")
legend(position=(anchor=:TR, width=3, offset=0.25), box=(pen=1, fill="gray95", shaded=true))
gmtend(:show)
A more complex example using the legend module.
using GMT
makecpt("-Cpanoply -T-8/8 > tt.cpt")
legend((
vspace=-0.25,
header=(text="My Map Legend", font=(24,"Times-Roman")),
hline=(pen=1, offset=0.5),
ncolumns=2,
vline=(pen=1, offset=0),
symbol1=(marker=:circ, size=0.4, dx_left=0.25, fill="p300/12", dx_right=0.75, text="This circle is hachured"),
symbol2=(marker=:ellipse, size=0.4, dx_left=0.25, fill=:yellow, dx_right=0.75, text="This ellipse is yellow"),
symbol3=(marker=:wedge, size=0.4, dx_left=0.25, fill=:green, pen=0.25, dx_right=0.75, text="This wedge is green"),
symbol4=(marker=:fault, size=0.65,dx_left=0.25, fill=:blue, dx_right=0.75, text="This is a fault"),
symbol5=(marker="-", size=0.4, dx_left=0.25, pen=(0.25,:dash), dx_right=0.75, text="A contour"),
symbol6=(marker=:vector, size=0.65,dx_left=0.25, fill=:magenta, pen=0.5, dx_right=0.75, text="This is a vector"),
symbol7=(marker="i", size=0.4, dx_left=0.25, fill=:cyan, pen=0.25, dx_right=0.75, text="This triangle is boring"),
hline2=(pen=1, offset=0.5),
vline2=(pen=1, offset=0),
ncolumns2=1,
map_scale=(lon=5, lat=5, length="600+u+f"),
vspace2=0.13,

label=(txt="Smith et al., @%5%J. Geophys. Res., 99@%%, 2000", justify=:R, font=(9, "Times-Roman")),
vspace4=0.25,
text1="Let us just try some simple text that can go on a few lines. There is no easy way to predetermine",
text2="how many lines may be required so we may have to adjust the height to get the right size box."
),
region=(0,10,0,8), pos=(paper=(1.25,1.25), width=14, justify=:BL, spacing=1.2),
