Color bar

Plots requiring a color bar will automatically add one.

The add_color_bar() method allows to configure the default color bar.

Add a color bar.

Parameters
----------
position
    Position of the colorbar (top, bottom, left, right)
      - Default to bottom for maps
      - Default to right for graphics
params
    Bar's parameters.

Note

Color bar can be fully customized using AxeParams and changed at CasysPlot creation through the color_bar parameter of PlotParams.

from casys import AxeParams, CasysPlot, PlotParams

param = AxeParams(
    label={
        "label": "My Data",
        "fontsize": "x-small",
        "color": "red"
    },
    ticks={
        "labelsize": "x-small",
        "labelcolor": "blue",
        "colors": "green",
        "width": 5,
    },
    values={
        "ticks": [0.1, 0.5, 0.7],
        "labels": ["low value", "medium value", "high value"],
    },
    position="right",
)


plot = CasysPlot(
    data=ad,
    data_name="SLA box stat",
    stat="std",
    plot_params=PlotParams(color_bar=param, color_limits=(0, 1)),
)

plot.show()

Tip

Using PlotParams kwargs_plot parameter allows to define non linear color scales.

from matplotlib.colors import LogNorm
from casys import AxeParams, CasysPlot, PlotParams

plot = CasysPlot(
    data=ad,
    data_name="Scatter Ku-band Range std / C-band Range std",
    plot_params=PlotParams(
        kwargs_plot={"norm": LogNorm(vmin=0.01, vmax=40)},
    ),
)

plot.show()
