Resources

The following cone.charts related application configuration options are available:

• cone.charts.luxon: Flag whether Luxon resources are delivered to browser. Defaults to false.

Chart Tile

Some chart basic tiles are available in cone.charts.

The following example shows how to implement a linechart:

from cone.charts.browser.chart import chart_tile
from cone.charts.browser.chart import LineChartTile

@chart_tile(
    name='my_linechart',
    interface=MyModel,
    permission='view')
class MyLineChart(LineChartTile):

    @staticmethod
    def chart_data(model, request):
        return {
            'labels': ['Label 1', 'Label 2'],
            'datasets': [{
                'data': [10, 20],
                'borderColor': 'rgb(255,0,0)',
                'tension': 0.3,
                'label': 'Dataset Label',
            }],
        }

Please refer to the source code in cone.charts.browser package for available chart tiles.

2.0.1 (2026-10-31)

• Extend the JS tests to 100 % coverage, all modules including bundles are loaded by the tests now. [rnix]

• Lint and format the JS code with biome. make check runs biome check, make format runs biome check --write (see include.mk). Behavior unchanged. [rnix]

• JS tooling: Commit pnpm-lock.yaml. Upgrade @web/test-runner to 1.0 and run the JS tests headless in Chromium via Playwright. Pin patched versions of vulnerable transitive dependencies via pnpm.overrides. [rnix]

• Sort the imports with ruff (one per line, from imports first, no sections) and format the code with ruff format (90 characters per line, single quotes). [rnix]

• Add import sorting (I rules) and the formatter settings to the ruff configuration in pyproject.toml. [rnix]

2.0.0 (2026-10-24)

• Require cone.app 2.0. treibstoff>1.99 is required already, which only cone.app 2.0 is compatible with. Check out cone.app and treibstoff from their 2.0 branches in mx.ini. [rnix]

• Modernise the code ruff flags as outdated: u'' prefixes, .format() over f-strings. Remove unused import. Behaviour unchanged. [rnix]

• Add qa.ruff domain to Makefile and pin the ruff rule selection in pyproject.toml, make check runs ruff check. [rnix]

• Pin setuptools<82.0.0 in mx.ini. pyramid 2.0.2 still imports pkg_resources, which setuptools 82 removed. [rnix]

1.1.0 (2026-02-03)

• Refactor package layout to use pyproject.toml and implicit namespace packages. [rnix]

• Setup Makefile. [lenadax]

• Run tests with pytest. [lenadax]

• Initial work. [rnix, toalba, lenadax]
