2D Scatter Map Plot

Below is an example of how to plot 2D data on a map plot using EMCPy’s plotting method.

import numpy as np
import matplotlib.pyplot as plt

from emcpy.plots import CreatePlot, CreateFigure
from emcpy.plots.map_tools import Domain, MapProjection
from emcpy.plots.map_plots import MapScatter


def main():
    # Create test data
    lats = np.linspace(35, 50, 30)
    lons = np.linspace(-70, -120, 30)

    # Create scatter plot on CONUS domian
    scatter = MapScatter(lats, lons)
    # change colormap and markersize
    scatter.color = 'tab:red'
    scatter.markersize = 25

    # Create plot object and add features
    plot1 = CreatePlot()
    plot1.plot_layers = [scatter]
    plot1.projection = 'plcarr'
    plot1.domain = 'conus'
    plot1.add_map_features(['coastline', 'states'])
    plot1.add_xlabel(xlabel='longitude')
    plot1.add_ylabel(ylabel='latitude')
    plot1.add_title(label='EMCPy Map', loc='center',
                    fontsize=20)

    fig = CreateFigure()
    fig.plot_list = [plot1]
    fig.create_figure()

    plt.show()


if __name__ == '__main__':
    main()
