復制代碼 代碼如下:

private void MakeLineChart()
{

string[] DataName = { "星期一", "星期二", "星期三", "星期四", "星期五", "星期六", "星期日" };
//第一條曲線的數據
int[] Data = { 0, 10, 20, 100, 40, 50, 60 };
//第二條曲線的數據
int[] Data1 = { 100, 50, 41, 86 };
//第三條曲線的數據
int[] Data2 = { 10, 50, 100, 30, 50, 60 };
string strValue1 = "";
string strValue = "";
string strValue2 = "";
string strCateory = "";
//循環取得數據并格式化為OWC10需要的格式,(加'/t')
for (int i = 0; i < DataName.Length; i++)
{
strCateory += DataName[i] + '/t';
}
for (int i = 0; i < Data.Length; i++)
{
strValue += Data[i].ToString() + '/t';
}
for (int i = 0; i < Data1.Length; i++)
{
strValue1 += Data1[i].ToString() + '/t';
}
for (int i = 0; i < Data2.Length; i++)
{
strValue2 += Data2[i].ToString() + '/t';
}
