I am building the app in which I want to plot two separate graphs from two data frames. I would like to use the dropdown to display only one graph per page based on each data frame (df,df1).
I followed the Plotly reference and couldn't reproduce it on my example.
This is my code so far that works (it displays both graphs on the same page, without dropdown):
import pandas as pd
import dash
import plotly.express as px
import dash_core_components as dcc
import dash_html_components as html
app = dash.Dash(__name__)
data = [['Blue',20],['Red ',12],['Green',33]]
df = pd.DataFrame(data,columns=['Color','Number'])
data1 = [['A',10,88],['B ',50,45],['C',25,120]]
df1 = pd.DataFrame(data1,columns=['Letter','Column1','Column2'])
fig = px.bar(df, x=df['Color'], y=df['Number'])
fig1 = px.line(x=df1['Letter'], y=df1['Column1'], color=px.Constant('Column1'),
labels=dict(x='Letter', y='Column1', color='Letter'))
fig1.add_bar(x=df1['Letter'], y=df1['Column2'], name='Letter')
app.layout = html.Div(children=[
html.H1(children='Colors and Letters', style={'text-align': 'center'}),
html.Div(children='Color', style={'text-align': 'center'}),
dcc.Graph(
id='example-graph',
figure=fig
),
html.Div(children='Letter', style={'text-align': 'center'}),
dcc.Graph(
id='example-graph1',
figure=fig1
)
])
if __name__ == '__main__':
app.run_server(debug=True)
This is what I would like to get:
What would be the best approach to do this?
Thanks in advance.
I don't have much experience with Dash, but here's a great answer and your code throughout. The point is to introduce a dropdown so that the initial value is displayed as fig. Depending on the return value of the callback function, I use the if function to switch the graph.
import pandas as pd
import plotly.express as px
import dash
import dash_core_components as dcc
import dash_html_components as html
from dash.dependencies import Input, Output
app = dash.Dash(__name__)
data = [['Blue',20],['Red ',12],['Green',33]]
df = pd.DataFrame(data,columns=['Color','Number'])
data1 = [['A',10,88],['B ',50,45],['C',25,120]]
df1 = pd.DataFrame(data1,columns=['Letter','Column1','Column2'])
app.layout = html.Div(children=[
html.H1(children='Colors and Letters', style={'text-align': 'center'}),
html.Div(children='Color', style={'text-align': 'center'}),
html.Div([
html.Label(['Choose a graph:'],style={'font-weight': 'bold'}),
dcc.Dropdown(
id='dropdown',
options=[
{'label': 'graph1', 'value': 'graph1'},
{'label': 'graph2', 'value': 'graph2'},
],
value='graph1',
style={"width": "60%"}),
html.Div(dcc.Graph(id='graph')),
]),
])
#app.callback(
Output('graph', 'figure'),
[Input(component_id='dropdown', component_property='value')]
)
def select_graph(value):
if value == 'graph1':
fig = px.bar(df, x=df['Color'], y=df['Number'])
return fig
else:
fig1 = px.line(x=df1['Letter'], y=df1['Column1'], color=px.Constant('Column1'),
labels=dict(x='Letter', y='Column1', color='Letter'))
fig1.add_bar(x=df1['Letter'], y=df1['Column2'], name='Letter')
return fig1

I would like to add a range slider along with my dropdown, and make the range slider the 'Wallclock' datetime along with an interaction that allows the range slider to chose the datetime for that capsules based on the dropdown value. I managed to find several ways that other people have done this but none seems to work for my situation especially the callback and the update of the graph. Thank you!

obviously I don't have access to your Excel spreadsheet so generated a data frame with same shape
taken approach of using a second figure with a rangeslider for slider capability
updated callback to use this figure as input for date range

New to Plotly Dash.
I’m working through the tutorial on my simple example. Learning how to update a graph when new data is added to the data frame (two data frames in this case) and how to connect this with the dropdown that I have on my dashboard.
I want my graphs to get updated with new data on each page load or page refresh (as I will have only a few updates per day.)
This is the code I'm working on:
import pandas as pd
import plotly.express as px
import dash
import dash_core_components as dcc
import dash_html_components as html
from dash.dependencies import Input, Output
app = dash.Dash(__name__)
data = [['Blue', 20], ['Red ', 12], ['Green', 33]]
df = pd.DataFrame(data, columns=['Color', 'Number'])
data1 = [['A', 10, 88], ['B ', 50, 45], ['C', 25, 120]]
df1 = pd.DataFrame(data1, columns=['Letter', 'Column1', 'Column2'])
fig = px.bar(df, x=df['Color'], y=df['Number'])
fig1 = px.line(x=df1['Letter'], y=df1['Column1'], color=px.Constant('Column1'),
labels=dict(x='Letter', y='Column1', color='Letter'))
fig1.add_bar(x=df1['Letter'], y=df1['Column2'], name='Letter')
app.layout = html.Div(children=[
html.H1(children='Colors and Letters', style={'text-align': 'center'}),
html.Div(children='Color', style={'text-align': 'center'}),
html.Div([
html.Label(['Choose a graph:'], style={'font-weight': 'bold'}),
dcc.Dropdown(
id='dropdown',
options=[
{'label': 'Colors', 'value': 'graph1'},
{'label': 'Letters', 'value': 'graph2'},
],
value='graph1',
style={"width": "60%"}),
html.Div(dcc.Graph(id='graph')),
]),
])
#app.callback(
Output('graph', 'figure'),
[Input(component_id='dropdown', component_property='value')]
)
def select_graph(value):
if value == 'graph1':
return fig
else:
return fig1
if __name__ == '__main__':
app.run_server(debug=True)
Any help would be greatly appreciated. Thanks in advance.
As documented in the section on live update, you should be able to achieve the desired behaviour by defining a function that creates the layout,
def layout():
return html.Div(...)
and assigning this function as the app layout,
app.layout = layout # note no (), you must assign the function itself, not the layout
I'm having so many issues align my map componants to the left of my data grid componant. I want each componant side by side. I have tried adding Divs, included attibutes and changing style. Please help.

Is it possible to have a dash app within a Jupyter Notebook, rather than served up and viewed in a browser?
My intention is to link graphs within a Jupyter notebook so that hovering over one graph generates the input required for another graph.
(Disclaimer, I help maintain Dash)
See https://github.com/plotly/jupyterlab-dash. This is a JupyterLab extension that embeds Dash within Jupyter.
Also see alternative solutions in the Dash Community Forum like the Can I run dash app in jupyter topic.
There's already a great answer to this question, but this contribution will focus directly on:
1. How to use Dash within Jupyterlab, and
2. how to select graphing input by hovering over another graph
Following these steps will unleash Plotly Dash directly in JupyterLab:
1. Install the latest Plotly version
2. Installl JupyterLab Dash with conda install -c plotly jupyterlab-dash
3. Using the snippet provided a bit further down launch a Dash app that contains an animation built on a pandas dataframe that expands every second.
Screenshot of the Dash in JupyterLab (code in snippet below)
This image shows Dash literally fired up inside JupyterLab. The four highlighted sections are:
1 - Cell. A cell in a .ipynb that you're already probably very familiar with
2 - Dash. A "live" dash app that expands all three traces with a random number and shows the updated figure every second.
3 - Console. An console where you can inspect available elements in your script using, for example, fig.show
4 - mode. This shows where some true magic resides:
app.run_server(mode='jupyterlab', port = 8090, dev_tools_ui=True, #debug=True,
dev_tools_hot_reload =True, threaded=True)
You can choose to fire up the dash app in:
Jupyterlab, like in the screenshot with mode='jupyterlab',
or in a cell, using mode='inline':
or in your default browser using mode='external'
Code 1:
import pandas as pd
import numpy as np
import plotly.express as px
import plotly.graph_objects as go
from jupyter_dash import JupyterDash
import dash_core_components as dcc
import dash_html_components as html
from dash.dependencies import Input, Output
# code and plot setup
# settings
pd.options.plotting.backend = "plotly"
# sample dataframe of a wide format
np.random.seed(4); cols = list('abc')
X = np.random.randn(50,len(cols))
df=pd.DataFrame(X, columns=cols)
df.iloc[0]=0;
# plotly figure
fig = df.plot(template = 'plotly_dark')
app = JupyterDash(__name__)
app.layout = html.Div([
html.H1("Random datastream"),
dcc.Interval(
id='interval-component',
interval=1*1000, # in milliseconds
n_intervals=0
),
dcc.Graph(id='graph'),
])
# Define callback to update graph
#app.callback(
Output('graph', 'figure'),
[Input('interval-component', "n_intervals")]
)
def streamFig(value):
global df
Y = np.random.randn(1,len(cols))
df2 = pd.DataFrame(Y, columns = cols)
df = df.append(df2, ignore_index=True)#.reset_index()
df.tail()
df3=df.copy()
df3 = df3.cumsum()
fig = df3.plot(template = 'plotly_dark')
#fig.show()
return(fig)
app.run_server(mode='jupyterlab', port = 8090, dev_tools_ui=True, #debug=True,
dev_tools_hot_reload =True, threaded=True)
But the good news does not end there, regarding:
My intention is to link graphs within a Jupyter notebook so that
hovering over one graph generates the input required for another
graph.
There's a perfect example on dash.plotly.com that will do exactly that for you under the paragraph Update Graphs on Hover:
I've made the few necessary changes in the original setup to make it possible to run it in JupyterLab.

I am not sure dash apps can be displayed within a Jupyter notebook. But if what you're looking for is using sliders, combo boxes and other buttons, you may be interested in ipywidgets that come from Jupyter directly.
These may be used with plotly, as shown here.
EDIT
Eventually it seems that there are solutions to embed dash apps inside Jupyter by using an iframe and IPython.display.display_html().
See this function and this GitHub repo for details.
See https://medium.com/plotly/introducing-jupyterdash-811f1f57c02e
$ pip install jupyter-dash
from jupyter_dash import JupyterDash
app = JupyterDash(__name__)
<your code>
app.run_server(mode='inline')
Look for plotly offline.
Say you have a figure (e.g. fig = {'data': data, 'layout':layout} )
Then,
inside a jupyter notebook cell,
from plotly.offline import iplot, init_notebook_mode
init_notebook_mode()
# plot it
iplot(fig)
This will plot the plotly inside your jupyter. You dont even have to run the flask server.
