Installation

$ pip install pyg2plot

Usage

render HTML

from pyg2plot import Plot

line = Plot("Line")

line.set_options({
  "data": [
    { "year": "1991", "value": 3 },
    { "year": "1992", "value": 4 },
    { "year": "1993", "value": 3.5 },
    { "year": "1994", "value": 5 },
    { "year": "1995", "value": 4.9 },
    { "year": "1996", "value": 6 },
    { "year": "1997", "value": 7 },
    { "year": "1998", "value": 9 },
    { "year": "1999", "value": 13 },
  ],
  "xField": "year",
  "yField": "value",
})

# 1. render html file
line.render("plot.html")
# 2. render html string
line.render_html()

render Jupyter

from pyg2plot import Plot

line = Plot("Line")

line.set_options({
  "height": 400, # set a default height in jupyter preview
  "data": [
    { "year": "1991", "value": 3 },
    { "year": "1992", "value": 4 },
    { "year": "1993", "value": 3.5 },
    { "year": "1994", "value": 5 },
    { "year": "1995", "value": 4.9 },
    { "year": "1996", "value": 6 },
    { "year": "1997", "value": 7 },
    { "year": "1998", "value": 9 },
    { "year": "1999", "value": 13 },
  ],
  "xField": "year",
  "yField": "value",
})

# 1. render in notebook
line.render_notebook()

# 2. render in jupyter lab
line.render_jupyter_lab()

use JavaScript callback

from pyg2plot import Plot, JS

line = Plot("Line")

line.set_options({
  "height": 400, # set a default height in jupyter preview
  "data": [
    { "year": "1991", "value": 3 },
    { "year": "1992", "value": 4 },
    { "year": "1993", "value": 3.5 },
    { "year": "1994", "value": 5 },
    { "year": "1995", "value": 4.9 },
    { "year": "1996", "value": 6 },
    { "year": "1997", "value": 7 },
    { "year": "1998", "value": 9 },
    { "year": "1999", "value": 13 },
  ],
  "xField": "year",
  "yField": "value",
  "lineStye": JS('''function() {
    return { stroke: 'red' }; 
  }''')
})

Use JS API, you can use JavaScript syntax for callback.

API

Now, only has one API of pyg2plot.

• Plot

1. Plot(plot_type: str): get an instance of Plot class.

2. plot.set_options(options: object): set the options of G2Plot into instance.

3. plot.render(path, env, **kwargs): render out html file by setting the path, jinja2 env and kwargs.

4. plot.render_notebook(env, **kwargs): render plot on jupyter preview.

5. plot.render_jupyter_lab(env, **kwargs): render plot on jupyter lab preview.

6. plot.render_html(env, **kwargs): render out html string by setting jinja2 env and kwargs.

7. plot.dump_js_options(env, **kwargs): dump js options by setting jinja2 env and kwargs, use it for HTTP request.

More apis is on the way.
