2D Plots: Styling

Customize plot appearance with colors, markers, line styles, and custom ticks.

from tikzfigure import TikzFigure

Colors and markers

Section titled “Colors and markers”

pgfplots supports named colors and various marker types:

fig = TikzFigure()


ax = fig.axis2d(xlabel="Month", ylabel="Temperature", xlim=(0, 13), grid=True)


months = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12]
temp_seattle = [-5, -4, 0, 5, 10, 15, 18, 17, 12, 6, 0, -4]
temp_phoenix = [12, 15, 18, 24, 30, 36, 38, 37, 33, 26, 18, 12]


ax.add_plot(months, temp_seattle, label="Seattle", color="blue", mark="o")
ax.add_plot(months, temp_phoenix, label="Phoenix", color="red", mark="square")


ax.set_legend(position="north west")
fig.show()

\begin{tikzpicture}
    \begin{axis}[xlabel=Month, ylabel=Temperature, xmin=0, xmax=13, grid=true, legend pos=north west]
        \addplot[color=blue, mark=o] coordinates {(1,-5) (2,-4) (3,0) (4,5) (5,10) (6,15) (7,18) (8,17) (9,12) (10,6) (11,0) (12,-4)};
        \addplot[color=red, mark=square] coordinates {(1,12) (2,15) (3,18) (4,24) (5,30) (6,36) (7,38) (8,37) (9,33) (10,26) (11,18) (12,12)};
        \legend{Seattle, Phoenix}
    \end{axis}
\end{tikzpicture}

Available markers: o (circle), * (star), square, triangle, diamond, x, +

Available colors: red, blue, green, black, plus mixing like blue!50!red

Line styles and thickness

Section titled “Line styles and thickness”

Customize line appearance with options and line_width:

fig = TikzFigure()


ax = fig.axis2d(xlabel="$X$", ylabel="$Y$", xlim=(0, 10), grid=True)


x = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
y1 = [0, 1, 4, 9, 16, 25, 36, 49, 64, 81, 100]
y2 = [0, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20]


ax.add_plot(x, y1, label="Thick solid", color="red", line_width="2pt")
ax.add_plot(x, y2, label="Thin dashed", color="blue", dashed=True)


ax.set_legend()
fig.show()

\begin{tikzpicture}
    \begin{axis}[xlabel=$X$, ylabel=$Y$, xmin=0, xmax=10, grid=true, legend pos=north east]
        \addplot[color=red, line width=2pt] coordinates {(0,0) (1,1) (2,4) (3,9) (4,16) (5,25) (6,36) (7,49) (8,64) (9,81) (10,100)};
        \addplot[color=blue, dashed=True] coordinates {(0,0) (1,2) (2,4) (3,6) (4,8) (5,10) (6,12) (7,14) (8,16) (9,18) (10,20)};
        \legend{Thick solid, Thin dashed}
    \end{axis}
\end{tikzpicture}

options accepts pgfplots flags: "dashed", "dotted", "densely dashed", "only marks".

Custom ticks and labels

Section titled “Custom ticks and labels”

Control tick positions and labels:

fig = TikzFigure()


ax = fig.axis2d(xlabel="Grade", ylabel="Count", xlim=(0.5, 4.5), ylim=(0, 30))


ax.add_plot([1, 2, 3, 4], [5, 12, 18, 10], label="Students", color="green", mark="*")


# Custom x-axis labels
ax.set_ticks("x", [1, 2, 3, 4], labels=["A", "B", "C", "D"])


# Y-axis ticks at multiples of 5
ax.set_ticks("y", [0, 5, 10, 15, 20, 25, 30])


ax.set_legend()
fig.show()

        \addplot[color=green, mark=*] coordinates {(1,5) (2,12) (3,18) (4,10)};
        \legend{Students}
    \end{axis}
\end{tikzpicture}

Scatter plots (only marks)

Section titled “Scatter plots (only marks)”

Use options=["only marks"] to show only markers without connecting lines:

fig = TikzFigure()


ax = fig.axis2d(xlabel="X", ylabel="Y", xlim=(-1, 5), ylim=(-2, 10), grid=True)


# Noisy data points
x_data = [0, 1, 1.5, 2, 2.5, 3, 4]
y_data = [0, 0.9, 2.2, 3.8, 4.5, 6.2, 8.1]


# Fitted line
x_fit = [i * 0.1 for i in range(50)]
y_fit = [2 * x + 0.5 for x in x_fit]


ax.add_plot(
    x_data,
    y_data,
    label="Data",
    color="red",
    mark="o",
    mark_size="2pt",
    options=["only marks"],
)
ax.add_plot(x_fit, y_fit, label="Fit: y = 2x + 0.5", color="blue")


ax.set_legend(position="north west")
fig.show()

        \legend{Data, Fit: y = 2x + 0.5}
    \end{axis}

Axes on different layers

Section titled “Axes on different layers”

Axes can be assigned to layers to control stacking with other TikZ elements:

fig = TikzFigure()


ax = fig.axis2d(xlabel="X", ylabel="Y", xlim=(0, 5), ylim=(0, 5), layer=1)
ax.add_plot([0, 1, 2, 3, 4, 5], [0, 1, 2, 3, 4, 5], label="data", color="red")
ax.set_legend(position="north west")


# Background shape on layer 0
fig.add_node(
    2.5,
    2.5,
    label="bg",
    content="Background",
    shape="circle",
    minimum_size="4cm",
    fill="gray!20",
    draw="none",
    layer=0,
)


# Foreground annotation on layer 2
fig.add_node(
    4,
    4,
    label="fg",
    content="Foreground!",
    shape="rectangle",
    fill="yellow!30",
    layer=2,
)
