DragChartPanel  是java cs架构中的一种图形展现的开源组件。

业务需求需要用到DragChartPanel  ,这是一种根据jtable表格中的数据给与展示的图形组件。它和其他图形组件区别再与它可以进行拖拽,用户通过它不仅可以看出数据变化的曲线,而且可以通过拖拽修改表格中的数据。

下面展示一下它的效果图:

丑归丑,但是很实用呀。

下面展示它的代码

初始化坐标格图:

chartpanel1 = new DragChartPanel(this);
chartpanel1.setXtitle("时 间");
chartpanel1.setYtitle("负 荷(MW)");
chartpanel1.setDragLabel(jLabel1);
chartpanel1.setTm((DefaultTableModel) jTable1.getModel());
chartpanel1.setStartRow(0);
chartpanel1.setChartPanel(jPanel11);

绘制曲线:

private void drawGraph(int col) {
jLabel1.setText("");
int count = jTable1.getRowCount();
String[][] chartData1 = new String[1][count];
String[] chartIndex = new String[count];
DefaultTableModel tm = (DefaultTableModel) jTable1.getModel();
for (int i = 0; i < tm.getRowCount(); i++) {
      chartIndex[i] = tm.getValueAt(i, 0) == null ? "" : tm.getValueAt(i, 0).toString();
      chartData1[0][i] = tm.getValueAt(i, col) == null ? "" : tm.getValueAt(i, col).toString();
    }
    if (chartpanel1 != null) {
      chartpanel1.setEditColumn(col);
      chartpanel1.setData(chartData1);
      chartpanel1.setXLab(chartIndex);
      chartpanel1.setTitle(tm.getColumnName(col));
      chartpanel1.setLs_linename(new String[]{tm.getColumnName(col)});
      chartpanel1.getChart();
    }
  }

这个组件有一个缺点。只支持对列进行修改,这是这个组件的一个特点(拖动曲线表格的列会发生改动)。
为了使用它,很多表的结构就不得不迎合这一缺点。

例如如下表结构:

都是按列展示的。对于有些情况很不合理!如何解决(思考中。。。。。。)

上面思考的问题解决了!!!

源码中有这样一个字段:

再使用的过程中会出现如下情况:

这个时候你get哪个model就无所谓了,为了避免影响,随便弄一样不会发生改变的model吧。

这样,拖动曲线的时候,label的值会实时显示曲线的坐标。

那么,给上面的label 加一个监听,改变值的时候,将label的内容用“:”分割开,不刚好是x轴和y轴的值了吗?

对应横向表格中,直接再label监听事件中就可以更改table的值。(完美!!!)

注意一下:有时拖动x轴的坐标是很详细很详细的数据移动,是因为你选这了setIndex而不是setXLab

private void initChartline() {
     //填充 图形
    String[][] ChartData = new String[1][24];
    String[] ChartIndex = new String[24];
    if (fixTable.getRowCount() > 0) {
      for (int i = 0; i < dataTable.getColumnCount() - 2; i++) {
        ChartIndex[i] = String.valueOf(i);
        ChartData[0][i] = dataTable.getValueAt(fixtable_sld, i) == null ? "" : dataTable.getValueAt(fixtable_sld, i).toString();
      }
      if (dchartpanel_1 != null) {
        //String pdate = (String) fixTable.getValueAt(fixTable.getSelectedRow(), 3);
        dchartpanel_1.setLs_linename(new String[]{"联络线曲线" + "ceshi1" + "(MW)"});
        dchartpanel_1.setLcol(Lcol);
        dchartpanel_1.setXLab(ChartIndex);//setXLab 和setIndex的区别在于,setXLab拖动取值x轴是按照下标取值的,而setIndex则是拖动的位置,常常不是整数,推荐用前者
        dchartpanel_1.setData(ChartData);
        //dchartpanel_1.setIndex(ChartIndex);
        dchartpanel_1.getChart();
      }
    } 
  }
//曲线颜色
  private java.awt.Color[] Lcol = {    
    java.awt.Color.red,
    java.awt.Color.blue,
    java.awt.Color.blue};
