Posted by: wewe8866 Posted on: 2006-09-21 10:17 从数据库读取一系列的坐标点,(非整数)要把这些坐标点用直线连接起来,并显示,要求比例正常,无放大缩小,在网页中显示/ java库中好像没有非整数的绘图方法,如有请告知, 或者在jsp页面中使用javascrip??用什么方法?? 或者还有其他捷径??? 困扰很长时间的问题,求各位帮忙~~ | |

Posted by: wewe8866 Posted on: 2006-09-22 16:16 就是不想扩大数据,因为数据放大后,出图肯定就大,如何去缩回原来的大小,因为要做标准的图形,需要一比一的比例, 要么什么把图形类型转换成可以在客户端随意放大缩小一定倍数的(要有数值比例的)? 关于javascript,由于没使用过,不知如何实现,是不是更好?? | |

Posted by: lisliefor Posted on: 2006-09-25 11:49 Actually you can set the axis of coordinates enlager, so you need not to enlage picture . just like if the date enlage 10 times larger and your axis of coordinates' setting enlage 10 times larger . About javascript , are you sure that it can paint ? Applet ? Do you write before? Maybe you need to find some example ! Google please !! | |
