New Features:

Running Events Continuously

Gradio now supports the ability to run an event continuously on a fixed schedule. To use this feature,
pass every=# of seconds to the event definition. This will run the event every given number of seconds!

This can be used to:

• Create live visualizations that show the most up to date data
• Refresh the state of the frontend automatically in response to changes in the backend

Here is an example of a live plot that refreshes every half second:

import math
import gradio as gr
import plotly.express as px
import numpy as np


plot_end = 2 * math.pi


def get_plot(period=1):
    global plot_end
    x = np.arange(plot_end - 2 * math.pi, plot_end, 0.02)
    y = np.sin(2*math.pi*period * x)
    fig = px.line(x=x, y=y)
    plot_end += 2 * math.pi
    return fig


with gr.Blocks() as demo:
    with gr.Row():
        with gr.Column():
            gr.Markdown("Change the value of the slider to automatically update the plot")
            period = gr.Slider(label="Period of plot", value=1, minimum=0, maximum=10, step=1)
            plot = gr.Plot(label="Plot (updates every half second)")

    dep = demo.load(get_plot, None, plot, every=0.5)
    period.change(get_plot, period, plot, every=0.5, cancels=[dep])

demo.queue().launch()
