如何在python xlsxwriter中创建不从0开始的条形图?

我发现下面的图像完全由我想要创建的图表组成,但是我无法弄清楚如何在零以外的其他地方启动条形图。有人知道如何解决这个问题吗?

enter image description here

如评论中所述,它是带有up_down_bars的折线图。 我怎样才能得到一个这样的例子呢?

import xlsxwriter

workbook = xlsxwriter.Workbook('chart_line.xlsx')
worksheet = workbook.add_worksheet()
bold = workbook.add_format({'bold': 1})

# Add the worksheet data that the charts will refer to.
headings = ['Number', 'Batch 1', 'Batch 2']
data = [
    [2, 3, 4, 5, 6, 7],
    [10, 40, 50, 20, 10, 50],
    [30, 60, 70, 50, 40, 30],
]

worksheet.write_row('A1', headings, bold)
worksheet.write_column('A2', data[0])
worksheet.write_column('B2', data[1])
worksheet.write_column('C2', data[2])

# Create a new chart object. In this case an embedded chart.
chart1 = workbook.add_chart({'type': 'line'})

# Configure the first series.
chart1.add_series({
    'name':       '=Sheet1!$B$1',
    'categories': '=Sheet1!$A$2:$A$7',
    'values':     '=Sheet1!$B$2:$B$7',
})

# Configure second series. Note use of alternative syntax to define ranges.
chart1.add_series({
    'name':       ['Sheet1', 0, 2],
    'categories': ['Sheet1', 1, 0, 6, 0],
    'values':     ['Sheet1', 1, 2, 6, 2],
})

# Add a chart title and some axis labels.
chart1.set_title ({'name': 'Results of sample analysis'})
chart1.set_x_axis({'name': 'Test number'})
chart1.set_y_axis({'name': 'Sample length (mm)'})
chart1.set_up_down_bars({
    'up': {
        'fill':   {'color': '#00B050'},
        'border': {'color': 'black'}
    },
    'down': {
        'fill':   {'color': 'red'},
        'border': {'color': 'black'},
    },
})
# Set an Excel chart style. Colors with white outline and shadow.
chart1.set_style(10)

# Insert the chart into the worksheet (with an offset).
worksheet.insert_chart('D2', chart1, {'x_offset': 25, 'y_offset': 10})


workbook.close()

答案 0 :(得分:1)

我要猜测“无法弄清楚如何在零以外的地方启动条形码”你的意思是你不希望Y轴从0开始。

您可以像在Excel中一样更改它:通过更改轴范围的最小值。请参阅文档的set_x_axis()部分以及Working with Charts

chart.set_y_axis({'min': 10})

如果那不是你想要的,那么你可能需要澄清你的问题。

另外,为避免混淆,上图不是条形图。这是一个带有Up-Down栏的折线图。如果您需要一个条形图,该条形图也显示在文档和示例中。
