小编cur*_*guy的帖子

这是我的代码。我正在尝试连接/绘制中心和不同节点之间的路径。现在我想stroke为不同的路径制作不同的颜色。我创建了一个颜色数组，其中路径的笔触颜色是什么。但我不能把它stroke做成不同的颜色。

var lineFunction = d3.svg.line()
                     .x(function(d) { return d.x;})
                     .y(function(d) { return d.y;})
                     .interpolate("linear");
var lineGraph = vis.append("g")
                  .append("path")
                  .attr("d", lineFunction(CenterList))
                  .attr("stroke", function(d, i) { return ColorArr[i]; } )
                  .attr("stroke-width", 5)
                  .attr("fill", "none")
                  .attr("id", "viz");

ColorArr=black, black, red, red, black, black, black, red, black, red;

格拉法纳版本7.3.3。我在 之上创建了一个自定义变量JSON Datasource。下面的有效负载我用来填充变量选项$Project [{"text": "Proj1", "value": "1"}, {"text": "Proj2", "value": "2"}]。

现在，对于模板查询，我想使用text选定的 $Project dropdown 。例如 fields.Project:$Project.__text这样的事情。但我只得到value所选变量的 ，$Project而不是text.
有没有办法得到它。

这是我的d3.js代码段:

<script>


var width = 300,
height = 300,
margin = 20;
var x_centre = width/2;
var y_centre = height/2;
var nuclear_radius = 15;

var vis = d3.select("#chart_container").append("svg:svg")
.attr("width", width)
.attr("height", height);

var radiuses = [1,2,3];

var multiplier = (d3.min([width, height]) - 2*margin - nuclear_radius) / (d3.max(radiuses) * 2);

var shells = vis.selectAll("circle.shell")
 .data(radiuses)
 .enter().append("circle")
 .attr("class", "shell")
 .attr("cx", x_centre)
 .attr("cy", y_centre)
 .attr("r", function(d, i) { 
     return (d * multiplier);
  });

var nucleus = vis.selectAll('circle.nucleus')
.data(['nucleus'])
.enter().append("circle")
.attr("class", "nucleus")
.attr("cx", x_centre) …

我对 JSTL 很陌生。

现在我已经创建了一个 HashMap 并在 jsp 页面中呈现它。

这就是我创建 HashMap 的方式

在应用层：

public HashMap<String, String> uploadSmelter(){

HashMap<String, String> progress = new HashMap<String, String>();

try {
        CompanyEntity instanceNew = (CompanyEntity) sessionFactory.getCurrentSession()
                .createCriteria(CompanyEntity.class)
                .add(Restrictions.eq("name", smObj.getName()))
                .add(Restrictions.eq("metal",  MetalEnum.valueOf(metal))).uniqueResult();
        if (instanceNew != null){
            //logger.info();
            progress.put("error", Integer.toString(1));
            progress.put("errorMsg", "Company : " +smObj.getName() + " for Metal: " + metal + " exists." );

        }
     }
 return progress
}

在控制器级别：

HashMap<String, String> result = new HashMap<String, String>();
result.put("error", "0");        
result.put("update", "0");
result.put("create", "0");
HashMap<String, String> progress …

我创建了一个名为的地图result.

在sortByKeys方法中,因为我的键是带有数值的String,我将它们转换为Integer键类型Map然后对它们进行排序.

当我循环并单独打印时,排序工作正常,但是当我在另一个Map中设置它们时则不行.

public class TestDate {
    public static void main (String args[]){

    Map<String, String> result = new HashMap<String, String>();

        result.put("error", "10");
        result.put("1","hii");
        result.put("Update","herii");
        result.put("insert","insert");
        result.put("10","hiiuu");
        result.put("7","hii");
        result.put("21","hii");
        result.put("15","hii"); 

        Map<String, String> sorted = sortByKeys(result);
        //System.out.println(sorted);   
    }

    private static Map<String, String> sortByKeys(Map<String, String> map) {
        Map <Integer,String> unSorted = new  HashMap<Integer, String>();
        Map <String,String> sorted = new  HashMap<String, String>();
        for (Map.Entry<String, String> entry : map.entrySet())
        {
            try{
                int foo = Integer.parseInt(entry.getKey());            
                unSorted.put(foo, entry.getValue());                
            }catch (Exception e){

            } …

我打开了一张图片QHBoxLayout.我需要裁剪打开的图像并保存裁剪的图像.我怎样才能在PySide中做到这一点？

import sys
from PySide import QtGui, QtCore

class Example(QtGui.QWidget):

    def __init__(self):
        super(Example, self).__init__()

        self.initUI()

    def initUI(self):      

        hbox = QtGui.QHBoxLayout(self)
        pixmap = QtGui.QPixmap("re.png")

        lbl = QtGui.QLabel(self)
        lbl.setPixmap(pixmap)


        self.rect = QtCore.QRect()


        hbox.addWidget(lbl)
        self.setLayout(hbox)

        self.setGeometry(300, 300, 280, 170)
        self.setWindowTitle('Open Image')
        self.show()   
        # Tried here to implement Qpen      
        #self.painter = QtGui.QPainter(self)    
        #self.painter.setPen(QtGui.QPen(QtCore.Qt.black, 1, QtCore.Qt.SolidLine));
        #self.painter.drawRect(self.rect);
def main():

    app = QtGui.QApplication(sys.argv)
    ex = Example()
    sys.exit(app.exec_())


if __name__ == '__main__':
    main()
