使用 xslwriter 在图中创建点 [英] create point in graph using xslwriter

问题描述

我可以使用 Python 中的 xlsxwriter 通过线属性生成图形.但我需要把特定值上的 4 个点(菱形).谁能建议我如何使用 xlsxwriter 中的线属性将菱形放在特定值上.

I am able to generate graph using xlsxwriter in Python by line properties. But I need to put 4 dots(diamond) on the particular value. Can anyone suggest me How Can I put diamond on the particular value using line properties in xlsxwriter.

如果需要，我也可以发布代码.

if require than I can post the code also.

from openpyxl import load_workbook
from xlsxwriter.workbook import Workbook
import math
def graph(headline,table_percentage,table_threashold):
    """Create Graph Chart"""
    wb = load_workbook(filename = 'sample.xlsx')
    worksheet_final = wb.get_sheet_by_name(name='test')
    workbook = Workbook('graphs.xlsx')
    worksheet = workbook.add_worksheet()

    heading =['test1','test2','test3','test4','test5']
    worksheet.write_row('A1',heading)
    count =2
    while(count < worksheet_final.get_highest_row()):
        data_x = worksheet_final.cell(row = count, column = 1).value
        data_y = worksheet_final.cell(row = count, column = 2).value
        data_s1 = worksheet_final.cell(row = count, column = 8).value
        data_d0 = worksheet_final.cell(row = count, column = 14).value
        data_d1 = worksheet_final.cell(row = count, column = 20).value
        worksheet.write(count,0,round(data_x,0))
        worksheet.write(count,1,data_y)
        worksheet.write(count,2,data_s1)
        worksheet.write(count,3,data_d0)
        worksheet.write(count,4,data_d1)
        count = count + 1
    # Create a new chart with properties object.

    cellname = headline

    # Add a series to the chart.

   # Insert the chart into the worksheet.
    worksheet.insert_chart('K1', chart)
    workbook.close()

    table_percentage = "5%"
    table_threashold = {}
    #Need to put dot on the below 4 value
    table_threashold ['setup_mt1'] = [5,210]

    graph(headline,table_percentage,table_threashold)

推荐答案

在 XlsxWriter 无法打开系列中的单个点标记，但可以关闭带有标记的系列的点标记.为此，您需要使用 点(请参阅文档) 系列选项并关闭您不想要的标记.

In XlsxWriter it isn't possible to turn on individual point markers in a series but it is possible to turn point markers off for a series with markers. To do this you need to use the points (see docs) series option and turn off markers that you don't want.

from xlsxwriter.workbook import Workbook

workbook = Workbook('chart_point.xlsx')

worksheet = workbook.add_worksheet()
chart = workbook.add_chart({'type': 'line'})

data = [
    [1, 2, 3, 4, 5],
    [2, 4, 6, 8, 10],
    [3, 6, 9, 12, 15],

]

# Write the data for the chart.
worksheet.write_column('A1', data[0])
worksheet.write_column('B1', data[1])
worksheet.write_column('C1', data[2])

# Add a chart series with markers but turn some off.
chart.add_series({
    'categories': '=Sheet1!$A$1:$A$5',
    'values': '=Sheet1!$B$1:$B$5',
    'marker': {'type': 'automatic'},
    'points': [
            {'fill': {'none': True}, 'line': {'none': True}},
            {'fill': {'none': True}, 'line': {'none': True}},
            {'fill': {'none': True}, 'line': {'none': True}},
            {'fill': {'none': True}, 'line': {'none': True}},
    ],
})

# Add a second chart series.
chart.add_series({
    'categories': '=Sheet1!$A$1:$A$5',
    'values': '=Sheet1!$C$1:$C$5',
    'marker': {'type': 'automatic'},
    'points': [
            {'fill': {'none': True}, 'line': {'none': True}},
            {},
            {'fill': {'none': True}, 'line': {'none': True}},
            {'fill': {'none': True}, 'line': {'none': True}},
            {'fill': {'none': True}, 'line': {'none': True}},
    ],
})

worksheet.insert_chart('E9', chart)

workbook.close()

这意味着您只能指示属于系列的标记，即 XlsxWriter 中没有用于向不属于系列的图表添加点的功能.

This implies that you can only indicate markers that are part of the series, i.e., there is no facility in XlsxWriter for adding a point to a chart that isn't part of a series.
