Question

我们在from openpyxl.chart import ( Reference, Series, BarChart ) wb = load_workbook('revenue.xlsx') wsheet = wb.get_sheet_by_name('sales') print (wsheet) data = Reference(wsheet, min_col=5, min_row=2, max_col=5, max_row=10)方法中提到的元组是什么意思？在下面： -

data =   Reference(wsheet, (5, 2), (5, 10))

OR

import React , { Component } from 'react';
import { connect } from "react-redux";
import { fetchPrescriptionFromUrl } from '../actions/index.js';
import { Link } from 'react-router';
import PrescriptionNew from './new.jsx';
import '../app.css';

class PrescriptionIndex extends Component {

  componentDidMount(){
    this.props.fetchData(PORT+'/prescriptions');
  }

  render() {
    if (this.props.has_error){
      return(<p> Fetching an Api results in error</p>)
    }

    if (this.props.has_loading){
      return(<p> Loading...</p>)
    }
    return(
      <div>
        <PrescriptionNew /> 
        {this.props.prescriptions.prescriptions && this.props.prescriptions.prescriptions.map(function(data){
        return (
          <div className="image-prescription" key={data.id}>
            <Link to={"/update/" + data.id} >
              <img src={data.image_path.image_path.url} 
                className="prescription-image"
                alt="prescription" 
              />
            </Link>  
          </div>      
        );
      }); }
      </div>
    )
  }
}
export default PrescriptionIndex;

我浏览了一些文档，但对我来说并不是那么清楚

openpyxl.chart.reference的源代码相对较短。摘录如下。另请参阅OpenPyXL文档中的Creating a chart。参数(5, 2)和(5, 10)指的是Excel工作表中包含您正在绘制的图表数据的单元格范围的起点和终点。

class Reference(Strict):

    """
    Normalise cell range references
    """

    min_row = MinMax(min=1, max=1000000, expected_type=int)
    max_row = MinMax(min=1, max=1000000, expected_type=int)
    min_col = MinMax(min=1, max=16384, expected_type=int)
    max_col = MinMax(min=1, max=16384, expected_type=int)
    range_string = String(allow_none=True)

    def __init__(self,
                 worksheet=None,
                 min_col=None,
                 min_row=None,
                 max_col=None,
                 max_row=None,
                 range_string=None
                 ):
        if range_string is not None:
            sheetname, boundaries = range_to_tuple(range_string)
            min_col, min_row, max_col, max_row = boundaries
            worksheet = DummyWorksheet(sheetname)

我们在openpyxl.reference方法中提到的元组意味着什么？
