Question

我刚刚尝试了https://plot.ly/python/gauge-charts/中的代码，尽管它不起作用。你能指导我哪里出问题了吗？我是python的新手，也是密谋。这是代码：

import plotly.plotly as py

import plotly.graph_objs as go
from plotly.offline import *

base_chart = {
    "values": [40, 10, 10, 10, 10, 10, 10],
    "labels": ["-", "0", "20", "40", "60", "80", "100"],
    "domain": {"x": [0, .48]},
    "marker": {
        "colors": [
            'rgb(255, 255, 255)',
            'rgb(255, 255, 255)',
            'rgb(255, 255, 255)',
            'rgb(255, 255, 255)',
            'rgb(255, 255, 255)',
            'rgb(255, 255, 255)',
            'rgb(255, 255, 255)'
        ],
        "line": {
            "width": 1
        }
    },
    "name": "Gauge",
    "hole": .4,
    "type": "pie",
    "direction": "clockwise",
    "rotation": 108,
    "showlegend": False,
    "hoverinfo": "none",
    "textinfo": "label",
    "textposition": "outside"
}
meter_chart = {
    "values": [50, 10, 10, 10, 10, 10],
    "labels": ["Log Level", "Debug", "Info", "Warn", "Error", "Fatal"],
    "marker": {
        'colors': [
            'rgb(255, 255, 255)',
            'rgb(232,226,202)',
            'rgb(226,210,172)',
            'rgb(223,189,139)',
            'rgb(223,162,103)',
            'rgb(226,126,64)'
        ]
    },
    "domain": {"x": [0, 0.48]},
    "name": "Gauge",
    "hole": .3,
    "type": "pie",
    "direction": "clockwise",
    "rotation": 90,
    "showlegend": False,
    "textinfo": "label",
    "textposition": "inside",
    "hoverinfo": "none"
}
layout = {
    'xaxis': {
        'showticklabels': False,
        'autotick': False,
        'showgrid': False,
        'zeroline': False,
    },
    'yaxis': {
        'showticklabels': False,
        'autotick': False,
        'showgrid': False,
        'zeroline': False,
    },
    'shapes': [
        {
            'type': 'path',
            'path': 'M 0.235 0.5 L 0.24 0.65 L 0.245 0.5 Z',
            'fillcolor': 'rgba(44, 160, 101, 0.5)',
            'line': {
                'width': 0.5
            },
            'xref': 'paper',
            'yref': 'paper'
        }
    ],
    'annotations': [
        {
            'xref': 'paper',
            'yref': 'paper',
            'x': 0.23,
            'y': 0.45,
            'text': '50',
            'showarrow': False
        }
    ]
}

# we don't want the boundary now
base_chart['marker']['line']['width'] = 0

fig = {"data": [base_chart, meter_chart],
       "layout": layout}
# fig.show()

py.iplot(fig, filename='gauge-meter-chart')

实际上，我想构建一种具有一些笔触的游标，并将其值写在上面。所以任何人都可以帮助我，我会很感激。预先感谢。

您可以将Plotly设置为在联机或脱机模式下工作。要在线工作，您需要一个用户名

要离线工作，只需将代码编辑为

import plotly
import plotly.graph_objs as go
from plotly.offline import *

...
...

plotly.offline.plot(fig, filename='gauge-meter-chart.html')

iplot（）无法正常工作。为什么呢是否需要帐号？
