Easily create data visualization of static or streaming data

Get Started

pip install easycharts

Create EasyCharts Server

# charts.py
from fastapi import FastAPI
from easycharts import ChartServer

server = FastAPI()

@server.on_event('startup')
async def setup():
    server.charts = await ChartServer.create(
        server,
        charts_db="test"
    )

    await server.charts.create_dataset(
        "test",
        labels=['a', 'b', 'c', 'd'],
        dataset=[1,2,3,4]
    )

Start Server

uvicorn --host 0.0.0.0 --port 0.0.0.0 charts:server

easycharts's Issues

Unable to specify other chart types - defaults to bar

Problem

Bart type is unable to be specified, defaulting to Bart type graphs

TODO

Fix selection to allow chart_type=bar|line for graph pages

Possible to add more than 2 charts in 1 dashboard ?

Thanks for writing this, works great.
Write now the extra chart logic looks like this :

easycharts/easycharts/charts.py

Line 63 in 556a50a

charts.append(extra)

It looks like support for adding more than 2 charts on a single dashboard is not possible, is it a bug or a feature ?
Using .extend with ?extra=[chart_a, chart_b, chart_c ...] should solve this ?

What do you think ?

KeyError: 'serialization'

I get an error when trying to run the example:
