# Examples from pyvista.Plotter.remove_chart
# ==========================================

# First define a function to add two charts to a renderer.
import pyvista as pv
def plotter_with_charts():
    pl = pv.Plotter()
    pl.background_color = 'w'
    chart_left = pv.Chart2D(size=(0.5, 1))
    _ = chart_left.line([0, 1, 2], [2, 1, 3])
    pl.add_chart(chart_left)
    chart_right = pv.Chart2D(size=(0.5, 1), loc=(0.5, 0))
    _ = chart_right.line([0, 1, 2], [3, 1, 2])
    pl.add_chart(chart_right)
    return pl, chart_left, chart_right
pl, *_ = plotter_with_charts()
pl.show()

# Now reconstruct the same plotter but remove the right chart by index.
pl, *_ = plotter_with_charts()
pl.remove_chart(1)
pl.show()

# Finally, remove the left chart by reference.
pl, chart_left, chart_right = plotter_with_charts()
pl.remove_chart(chart_left)
pl.show()
