I'm using taipy==1.1 and I have an issue with the rendering of my charts.

Here is a snippet of my code:

import pandas as pd

from taipy import Gui

...

total_cost = dataset['costInUsd'].sum()

daily_costs = dataset.groupby(['date', 'costInUsd']).sum().reset_index()
regions_location = dataset[['date', 'resourceLocation']].groupby('resourceLocation').count().reset_index().rename(columns={'date': 'Number of resources', 'resourceLocation': 'Location'})
services_family = dataset[['date', 'serviceFamily']].groupby('serviceFamily').count().reset_index()
services_cost = dataset[['costInUsd', 'serviceFamily']].groupby('serviceFamily').sum().reset_index()
...
services_info = services_family.merge(services_cost).rename(columns={'serviceFamily': 'Family', 'costInUsd': 'Cost in USD', 'date': 'Number of resources'})


page = f"""
# Cost Analysis

Month to day cost: <|{total_cost}|>

<|
Daily costs:
<|{daily_costs}|chart|type=bar|width=90%|>

<|layout|gap=5px|columns=20% 60%|

# Create a Gui object with our page content
Gui(page=page).run(dark_mode=True)

I can run it but the interpreter prints warnings:

The page is rendered but without any graphs, here is a snippet:

My data frame looks good, here is the head relative to the previous screenshot:

CodePudding user response：

Try to delete the f before the page string. Taipy is formatting by itself the string to create controls (charts, buttons, tables, ...) and make the connections between the different variables.
