Plotly: ¿Cómo hacer una opción desplegable de índice múltiple?

Nov 19 2020

Tengo datos con el mismo número de índice para diferentes períodos de tiempo como se muestra a continuación

29700   2:59 PM 719350  689850  337.85  95.45   
29700   2:45 PM 786975  641575  360.00  108.35  
29700   2:30 PM 823500  626875  336.50  127.80  
29700   2:15 PM 812450  631800  308.55  143.00  
29700   2:00 PM 974700  617750  389.80  120.00  
29700   1:45 PM 1072675 547100  262.55  186.85  
29700   1:30 PM 1272300 469600  206.85  232.00  

usando el siguiente código, he hecho el gráfico:

subfig = make_subplots(specs=[[{"secondary_y": True}]])

# create two independent figures with px.line each containing data from multiple columns
fig = px.line(df,x='Time', y='Call OI')
fig2 = px.line(df,x='Time', y='Call LTP')

fig2.update_traces(yaxis="y2")

subfig.add_traces(fig.data + fig2.data)
subfig.layout.xaxis.title="Time"
subfig.layout.yaxis.title="OI"
subfig.layout.yaxis2.type="log"
subfig.layout.yaxis2.title="Price"
# recoloring is necessary otherwise lines from fig und fig2 would share each color
# e.g. Linear-, Log- = blue; Linear+, Log+ = red... we don't want this
subfig.for_each_trace(lambda t: t.update(line=dict(color=t.marker.color)))
subfig.show()

Quiero un menú desplegable que seleccione un índice diferente y los datos del gráfico cambien en consecuencia. Por ejemplo, si selecciono del menú desplegable 29600, solo muestra datos para ese número de índice y también hay una manera de voltear el eje x (tiempo) de izquierda a derecha. Gracias de antemano por cualquier solución.

Edición 2: sugerencia actualizada con conjunto de datos vinculado

Para utilizar el conjunto de datos completo proporcionado en el enlace , simplemente descargue ese contenido como un archivo csv, ábralo y copie el contenido, y luego ejecute el código a continuación para obtener la siguiente figura. Los datos se recogen utilizando dfi = pd.read_clipboard(sep=','). Realmente no hay necesidad de preocuparse por configurar 'Strike Pricecomo índice. Tenga en cuenta que el conjunto de datos tiene muchos 0valores, pero seleccionar, por ejemplo, 26100producirá al menos un resultado significativo:

Editar: sugerencia actualizada con giro de eje

Mi última sugerencia se basa en un ejemplo de la sección Share data between callbacksde dcc.Store y realiza los ajustes necesarios para que funcione en su caso de uso. También he incorporado una funcionalidad para cambiar los valores del eje x usando:fig.update_layout(xaxis = dict(autorange='reversed'))

Sugerencia 1


No ha especificado cómo está utilizando sus cifras. Pero suponiendo que esté en JupyterLab, recomendaría encarecidamente usar JupyterDash. Encuentro eso mucho más flexible que incorporar funciones desplegables directamente en la figura, como señalaron los principiantes en el enlace de los comentarios.

El fragmento de código a continuación le permitirá seleccionar de qué índice mostrar datos en la siguiente aplicación que está configurada para producir la figura 'inline'que significa en el propio cuaderno. Si está interesado en utilizar un enfoque como este, puedo ver si puedo implementar un botón para voltear el eje x también.
