from flet.plotly_chart import PlotlyChart
def main(page: ft.Page):
df = px.data.gapminder().query("continent=='Oceania'")
fig = px.line(df, x="year", y="lifeExp", color="country")
page.add(PlotlyChart(fig, expand=True))
ft.app(target=main)
Bar chart
The following example is based on original example from Plotly docs.
import plotly.express as px
import flet as ft
from flet.plotly_chart import PlotlyChart
def main(page: ft.Page):
df = px.data.gapminder().query("continent == 'Oceania'")
fig = px.bar(
df,
x="year",
y="pop",
hover_data=["lifeExp", "gdpPercap"],
color="country",
labels={"pop": "population of Canada"},
height=400,
)
page.add(PlotlyChart(fig, expand=True))
ft.app(target=main)
Pie chart

from flet.plotly_chart import PlotlyChart
def main(page: ft.Page):
labels = ["Oxygen", "Hydrogen", "Carbon_Dioxide", "Nitrogen"]
values = [4500, 2500, 1053, 500]
fig = go.Figure(data=[go.Pie(labels=labels, values=values)])
page.add(PlotlyChart(fig, expand=True))
ft.app(target=main)
Box chart
The following example is based on original example from Plotly docs.
import plotly.graph_objects as go
import flet as ft
from flet.plotly_chart import PlotlyChart
def main(page: ft.Page):
x = ['day 1', 'day 1', 'day 1', 'day 1', 'day 1', 'day 1',
'day 2', 'day 2', 'day 2', 'day 2', 'day 2', 'day 2']
fig = go.Figure()
fig.add_trace(go.Box(
y=[0.2, 0.2, 0.6, 1.0, 0.5, 0.4, 0.2, 0.7, 0.9, 0.1, 0.5, 0.3],
x=x,
name='kale',
marker_color='#3D9970'
))
fig.add_trace(go.Box(
y=[0.6, 0.7, 0.3, 0.6, 0.0, 0.5, 0.7, 0.9, 0.5, 0.8, 0.7, 0.2],

x=x,
name='carrots',
marker_color='#FF851B'
))
fig.update_layout(
yaxis_title='normalized moisture',
boxmode='group' # group together boxes of the different traces for each value of x
)
page.add(PlotlyChart(fig, expand=True))
ft.app(target=main)
Properties
figure
Plotly figure to draw - an instance of plotly.graph_objects.Figure
class.
original_size
True
to display chart in original size. False
(default) to display a chart that fits configured bounds.
isolated
Every time when a page or parent chart control are updated with page.update()
or Control.update()
methods respectively the chart is re-drawn by calling Plotly API. Frequent re-drawings of large charts could affect the performance of the entire Flet app.
Set isolated
to True
to enable explicit chart updates. To re-draw the chart call its update()
method.
