Streamlit component for Let's-Plot visualization library

Last update: Nov 03, 2022

Overview

streamlit-letsplot

This is a work-in-progress, providing a convenience function to plot charts from the Lets-Plot visualization library.

Example usage

import streamlit as st
from streamlit_letsplot import st_letsplot
import numpy as np
import lets_plot
from lets_plot import *

np.random.seed(12)
data = dict(
    cond=np.repeat(['A','B'], 200),
    rating=np.concatenate((np.random.normal(0, 1, 200), np.random.normal(1, 1.5, 200)))
)

a = ggplot(data, aes(x='rating', fill='cond')) + ggsize(500, 250) \
+ geom_density(color='dark_green', alpha=.7) + scale_fill_brewer(type='seq') \
+ theme(axis_line_y='blank')

# plots any Let's Plot visualization object
st_letsplot(a)

generateStaticHtmlPage() Exception

Already mentioned in issue #7.

I am still getting the following error when using st_letsplot: generateStaticHtmlPage() - Exception: Trying to access top level value not marked as @ThreadLocal or @SharedImmutable from non-main thread

Is there a workaround? Are there several methods gnerating the html page? Or is it a bug in streamlit or lets-plot?

KeyError if there is no ggsize

If I have a plot without ggsize like lp.ggplot(df, lp.aes(x='foo, y='bar')) + lp.geom_bar() then streamlit_letsplot throws an KeyError: 'ggsize' with a throwsback to File "C:\ProgramData\Anaconda3\envs\efleets39\lib\site-packages\streamlit_letsplot\__init__.py", line 24, in st_letsplot height=plot_dict["ggsize"]["height"]

Solution: Adding lp.ggsize(500, 250) to the plot works.
