DEPRECATED

Please use the monorepo at https://github.com/deephaven/deephaven-plugins

Custom implementation built on top of plotly express to make it compatible with deephaven tables.

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.

To unit test, run the following command from the root of the repo:

tox -e py

Usage

Once you have the plugin installed and the server started, the recommended way to import the package mirrors plotly express:

import deephaven.plot.express as dx

Then, you can create a table (or use an existing one) and start plotting

from deephaven.column import int_col, string_col
import deephaven.plot.express as dx
from deephaven import new_table

source = new_table([
    string_col("Categories", ["A", "B", "C"]),
    int_col("Values", [1, 3, 5]),
])

fig = dx.bar(table=source, x="Categories", y="Values")
