Pyechart drawing multiple Y-axis line graphs

pyechart Draw multiple lines y Axonometric chart

Draw three polylines , And use different y Axis ： Use the following data to draw a line chart , And set according to the unit y Axis

data ：

Adding y Use... For axis data yaxis_index Appoint y The index of the axis ,`

line.add_yaxis(         # The first curve 
    series_name='PM2.5',
    y_axis=pm25,
    label_opts=opts.LabelOpts(is_show=False),
    yaxis_index=0,      # Set up y Index axis 
    is_smooth=True,
)
line.add_yaxis(         # Add the second curve 
    series_name='AQI',
    y_axis=aqi,
    label_opts=opts.LabelOpts(is_show=False),
    yaxis_index=1,      # Set up y Index axis 
    is_smooth=True,
)
line.add_yaxis(         # Add a third curve 
    series_name='CO',
    y_axis=co,
    label_opts=opts.LabelOpts(is_show=False),
    yaxis_index=2,      # Set up y Axis 
    is_smooth=True,
)

Use extend_axis Method add y Axis and specify format ,position Parameter settings add y Axis position ,position='left' For the left ,position='right' For the right ;offset Parameter settings y Distance between axes . Added y Axis index from yaxis_index=1 Start .yaxis_index=0 Mainly y Axis , stay set_global_opts Set its specific format in .

line.extend_axis(
    yaxis=opts.AxisOpts(type_='value', position='right'))
line.extend_axis(
    yaxis=opts.AxisOpts(
        name='mg/m³', 
        type_='value',
        position='left', offset=40))
