Usage

Use this widget by including:

<field name="field_text_json" widget="json_graph" />

For example:

<field name="values_data" widget="json_graph"/>

The JSON needs to be like:

fields = ['field1', 'field2', 'field3', ...]
field_x = 'field_x'
dictionary = self.value_ids.sorted(field_x).read(fields)
color = {
    'field1': HEXCOLOR1,
    'field2': '#FFBB78',
    'field3': '#1F77B4',
    ...
}
dictionary = self.value_ids.sorted(field_x).read(fields)
content = {}
data = []
for field in fields:
    if field != field_x:
        content[field] = []
        for rec in dictionary:
            content[field].append({'x': rec[field_x], 'y': rec[field]})
        if field in color:
            data.append({'values': content[field], 'key': field,
                'color': color[field]})
            continue
        data.append({'values': content[field], 'key': field})
info = {
    'label_x': 'X Label',
    'label_y': 'Y label',
    'data': data
}
self.field_text_json = json.dumps(info)

For example:

fields = ['sequence', 'value', 'sma', 'cma']
field_x = 'sequence'
dictionary = self.value_ids.sorted(field_x).read(fields)
color = {
    'value': '#2CA02C',
    'sma': '#FFBB78'
}
dictionary = self.value_ids.sorted(field_x).read(fields)
content = {}
data = []
for field in fields:
    if field != field_x:
        content[field] = []
        for rec in dictionary:
            content[field].append({'x': rec[field_x], 'y': rec[field]})
        if field in color:
            data.append({'values': content[field], 'key': field,
                'color': color[field]})
            continue
        data.append({'values': content[field], 'key': field})
info = {
    'label_x': 'Sequence',
    'label_y': '',
    'data': data
}
self.values_data = json.dumps(info)

Known issues / Roadmap

• nolabel is ignored, this image will never bring a label, by default simply use an extra separator.
• A graph will always use 100% of the width, pending the css dynamic attribute.
• Height is harcoded.
