winform中chart图表的打印示例，如何显示预览，纸张设置等

帮你看了下，winform 中的chart好像没有打印方法。但有导出生成的方法，可以先生成后在打印

chart1SaveImage("d:\\ddBmp", SystemDrawingImagingImageFormatBmp);

你自己弄个路径，先生成的bmp，然后就用winfrom 的那些打印控件就行pageSetupDialog，printDocument，printPreviewDialog，printDialog

pageSetupDialog和printPreviewDialog的Docuent属性设置为printDocument,然后在printDocument的printpage方法中写

Bitmap bitmap = new Bitmap("d:\\ddBmp");

eGraphicsDrawImage(bitmap, eMarginBoundsLeft, eMarginBoundsTop);就行了

预览是thisprintPreviewDialog1ShowDialog(); ，打印是thisprintDocument1Print();，打印设置thispageSetupDialog1ShowDialog();

其实就是把那个chart图表生成的打印出来，关闭窗体时在给生成那个删了，如果怕生成的文件重名就用全局唯一标识

cCharTemp=getchar();主要是接受scanf("%c",&cCharPut);这里按的回车，执行程序时，你输入a，然后回车，实际上缓冲区接受的是两个字符，第一个是'a'第二个是‘\n'，scanf("%c",&cCharPut);只把a从缓冲区中取走，但是'\n'还在缓冲区。如果没有getchar这个语句，那么下面的语句scanf("%c",&cCharPut);就会直接读取缓冲区中的'\n‘而不会等到你再去输入字符。而getchar是取走缓冲区中一个字符，把回车给取走，缓冲区空了，你才能再次输入

这个是要设置y轴的值，如果你的数据都是140000以上 那么你可以把y轴的最小值设置成140000

private void SetAxisY()

{

Axis AxisY = new Axis()

{

LineColor = ColorFromArgb(64, 64, 64, 64),

// Y轴标签字体大小

LabelAutoFitMinFontSize = 10,

// Y轴标签显示样式

LabelStyle = new LabelStyle() { Format = "{#}0%" },

// 网格Y轴设置

MajorGrid = new Grid() { LineColor = ColorFromArgb(64, 64, 64, 64) },

// Y轴的最大值

Maximum = 1000,

// Y轴的最小值

Minimum = 0,

// Y轴标签间距

Interval = 500,

// 最小刻度

MajorTickMark = new TickMark() { TickMarkStyle = TickMarkStyleOutsideArea, Size = 500 },

};

SystemWindowsFormsDataVisualizationChartingChart c = new SystemWindowsFormsDataVisualizationChartingChart();

cChartAreas[0]AxisY = AxisY;
