勾选复选框时无法显示任何散景图

Question

我已经尝试了下面的代码来为每个元素生成散景图，当它们各自的复选框被选中时。 数据是一个 df，其中包含“id”、“data_point”、“max”、“min”等列在 id 旁边，图表应该显示复选框选择的任何 id 这应该发生在每个唯一 id 上。 对于一个唯一的 id，图表应该如下所示

data = df

if len(data) == 0:
    logging.debug(" No data")
else:
    req_hover = HoverTool(
        tooltips=[
            ('data_point: ', '@data_point'),
            ('id: ', '@id')])

    req_figure = figure(title='Graph', x_axis_label="Index", y_axis_label="id/data_point [ms]",
                        plot_width=800, plot_height=400, output_backend="webgl")

    req_figure.add_tools(handover_hover)

    id_values = data['id'].drop_duplicates()

    column_view_data = data[
        ['id', 'tag', 'sw', 'name']].drop_duplicates().dropna()
    column_view_data_source = ColumnDataSource(column_view_data)

    data_table = DataTable(selectable='checkbox', source=column_view_data_source, columns=columns, width=1450,
                           height=400, css_classes=['blueTable'])

    name_dict_req = {'name': [], 'legend': [], 'label': []}

    logging.info('START OF DRAWINGS')

    for ind, element in enumerate(elements):
        d = []
        for i, item in data.iterrows():
            it_color = Turbo256[random.randint(0, 255)]
            if element == item['id']:
                if item['data_point'] is None or str(item['data_point']) == '[]':
                    item['data_point'] = '0'
                else:
                    item['data_point'] = [float(x) for x in item['data_point'].strip('[').strip(']').split(',')]
                raw_data_element_count = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19,
                                          20]  # this is my x axis which will be 1 to 20

                d.append({'id': id,
                          'number of raw data points': data_point_element_count,
                          'data_point': item['data_point']})
                d_new = pd.DataFrame(d)
                name_glyph_req = req_figure.line(x='number of raw data points',
                                                 y='data_point',
                                                 line_width=2,
                                                 legend_label=str(item['id']),
                                                 source=d_new,
                                                 color=it_color)

                name_dict_req['name'].append(name_glyph_req)
                name_dict_req['label'].append(str(item['id']))

    logging.info('AFTER DRAWINGS LOOP')

    for label in range(len(data.id.unique())):
        name_dict_req['legend'].append(req_figure.legend.items[label])

    initial_value = []
    options = list(data.id.unique())
    for i, name in enumerate(options):
        options[i] = str(name)

    for i in range(len(options)):
        if name_dict_req['label'][i] in initial_value:
            name_dict_req['name'][i].visible = True
            name_dict_req['legend'][i].visible = True
        else:
            name_dict_req['name'][i].visible = False
            name_dict_req['legend'][i].visible = False

Answer 1

我想我没有在我的代码中的 customJS 调用中提供名称字典。 所以问题就在那里，即使我点击复选框，图表也没有显示
