DragChartPanel可拖拽曲线应用详解
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};
