有关zedgraph的 问题
我现在想要zedgraph控件在C#中画一条折线，横轴是质量，纵轴是浓度，现在我已经完成了横轴坐标为[0,2500,4250,5250,5750],纵轴与之对应的坐标为[0,50,75,100,125]，画出这条折线！由于小弟是初学者，知道这个问题对各位来说很简单，还请各位不吝赐教，写上详细代码！小弟不胜感激。。。在线等着各位的回复。。。 --------------------编程问答-------------------- http://blog.csdn.net/happy09li/article/details/7535388 --------------------编程问答--------------------您好，我看了一下您之前发的传值的贴子，我没有看懂，想请教您一下：我在Form1中定义了一个数组，想在Form2中调用Form1中这个数组的值，请问具体代码怎么写？谢谢！！！ --------------------编程问答--------------------
你把数组传过去就可以了啊
1.在Form2里定义
public int[] str{get;set;}
Form2中就可以用Form1中的数组了 也就是str
2. 在Form1里创建Form2对象，
Form2 f = new Form2();
f.str=//你要传的值
f.Show();

大哥，还请您指点迷津，我按您的说法去做了，但是显示有错误 --------------------编程问答-------------------- 哪里错误？
你能把你的代码贴出来 --------------------编程问答--------------------

这句你都有问题？你是要把数组传到from2是把，你的数组C呢？ C[m]是什么你知道么？
你那些代码时从哪里copy的？
把传值的2个地方改下，，
Form1：
for (int m = 0; m < c.Length; m++)
{
c[m] = array[m];
//dataGridView1.Rows[m].Cells[0].Value = Convert.ToInt32(c[m]);
form2a.str1= c;
}
for (int m = 0; m < c.Length - 1; m++)
{
for (int n = 0; n < dataGridView1.Rows.Count; n++)
{
if (c[m] >= select_arrry[2 * n] && c[m + 1] <= select_arrry[2 * n + 1])
{
SumFlimt[m] += Flimt[n];
SumMass[m] = SumFlimt[m] * (c[m + 1] - c[m]);
}
else
continue;
}
CumMass += SumMass[m];
cummass[m + 1] = CumMass;
TheoryFlimt[m] = (double)(CumMass / c[m + 1]);
}
for(int d=0;d<c.Length;d++)
{
form2a.str2 = cummass;//你要传的值
}
form2a.Show(); --------------------编程问答-------------------- C[m]我知道，因为代码太长，我就没往上放 --------------------编程问答-------------------- --------------------编程问答-------------------- http://sourceforge.net/projects/zedgraph/files/ --------------------编程问答--------------------
？你知道，，那你说c[m]是什么？ --------------------编程问答-------------------- 8楼的给你代码传值是没问题的，，再有问题就是你其他地方的问题了
补充：.NET技术 , C#
