Deephaven Plugin for Plotly

The Deephaven Plugin for Plotly. Allows for opening Plotly plots in a Deephaven environment. Any Plotly plot should be viewable by default. For example:

Scatter Plot

import plotly.express as px
df = px.data.iris()
fig = px.scatter(df, x="sepal_width", y="sepal_length", color="species",
                 size='petal_length', hover_data=['petal_width'])

Box Plot

import plotly.express as px
df = px.data.tips()
fig = px.box(df, x="time", y="total_bill")

Multiple Series

It's possible to have multiple kinds of series in the same figure. Here is an example driving a line and a bar plot:

from plotly.subplots import make_subplots
import plotly.graph_objects as go
fig = make_subplots(rows=1, cols=2)
fig.add_trace(
    go.Scatter(x=[1, 2, 3], y=[4, 5, 6]),
    row=1, col=1)
fig.add_trace(
    go.Bar(x=[1, 2, 3], y=[4, 5, 6], marker=dict(color=[4, 5, 6], coloraxis="coloraxis")),
    row=1, col=2)
fig.update_layout(title_text="Side By Side Subplots", showlegend=False)

Plot data from a Deephaven table

from deephaven import empty_table, numpy
import plotly.express as px
t = empty_table(300).update(formulas=["X = (double)i", "Y = Math.sin(X)"])
data = numpy.to_numpy(t, ["X", "Y"])
fig = px.line(x=data[:,0], y=data[:,1])

Build

To create your build / development environment:

python -m venv .venv
source .venv/bin/activate
pip install --upgrade pip setuptools
pip install build deephaven-plugin plotly

To build:

python -m build --wheel

The wheel is stored in dist/.

To test within deephaven-core, note where this wheel is stored (using pwd, for example). Then, follow the directions in the deephaven-js-plugins repo.
