Dragchartpanel drag curve application details
•
Java
Dragchartpanel is an open source component for graphical presentation in Java CS architecture.
Business requirements need to use dragchartpanel, which is a graphical component displayed according to the data in JTable table. It is different from other graphic components and can be dragged. Users can not only see the curve of data change, but also modify the data in the table by dragging.
Here's the rendering:
Ugly is ugly, but it's very practical.
Here's the code
Initialize grid:
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);
Draw curve:
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();
}
}
This component has one drawback. Only column modification is supported, which is a feature of this component (the column of the curve table will be changed when dragging). In order to use it, the structure of many tables has to cater to this disadvantage.
For example, the following table structure:
They are displayed by column. It is unreasonable for some situations! How to solve (thinking...)
The above problems have been solved!!!
There is such a field in the source code:
During reuse, the following situations will occur:
At this time, it doesn't matter which model you get. In order to avoid influence, just get a model that won't change.
In this way, when dragging the curve, the value of label will display the coordinates of the curve in real time.
Then, add a monitor to the above label. When changing the value, separate the label content with ":". Isn't it just the value of x-axis and y-axis?
In the corresponding horizontal table, you can change the value of table directly in the label listening event. (perfect!!!)
Note: sometimes dragging the x-axis coordinates is a very detailed data movement because you selected setindex instead of 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();
}
}
}
