[英]There is a line in the bottom part of the graph that joins the last point while using zedgraph. How can I remove this?
这是我的代码:
我正在尝试从文件夹中获取CSV文件。 之后,我从这些文件中获取数据并将它们存储在zedX和zedY列表中。 我将这两个数组传递给zedgraphControl。
我正在正确地获得情节。 但是,有一条直线从0连接到图形的最后一点。 我应该如何删除呢?
//I am taking in a folder which have CSV files containing a data. So, iterating over files in the outer loop
for (int i = 0; i < inputFolder.Count; i++)
{
//Lists to contain the data
List<Double> zedXList = new List<double>();
List<Double> zedYList = new List<double>();
//Arrays to be passed into zedgraph
double[] zedX = new double[thisbin.IndLists[i].Count()];
double[] zedY = new double[thisbin.IndLists[i].Count()];
for (int l = 0; l < thisbin.IndLists[i].Count(); l++)
{
zedX[l] = 0;
zedY[l] = 0;
}
//In the inner loop I fetch the data from the file and store it in lists
for (int j = 0; j < thisbin.IndLists[i].Count(); j++)
{
if (j % 2 == 0)
{
zedXList.Add(thisbin.IndLists[i][j]);
}
if (j % 2 != 0)
{
zedYList.Add(thisbin.IndLists[i][j]);
}
}
//from the lists I pass the data into arrays, in order to pass it into zedgraph
for (int k = 0; k < zedXList.Count(); k++)
{
zedX[k] = Convert.ToDouble(zedXList[k]);
zedY[k] = Convert.ToDouble(zedYList[k]);
}
//zedgraph plot
string title = "PLOT-" + Convert.ToString(i + 1);
TabPage myTabPage = new TabPage(title);
var zed = new ZedGraphControl();
zed.Dock = DockStyle.Fill;
zed.Size = new System.Drawing.Size(575, 312);
zed.GraphPane.CurveList.Clear();
var Indpane2 = zed.GraphPane;
Indpane2.Title.Text = "PLOT" + Convert.ToString(i + 1);
Indpane2.XAxis.Title.Text = "m/z";
Indpane2.YAxis.Title.Text = "Intensity";
var ind2 = new PointPairList(zedX, zedY);
var IndCurve2 = Indpane2.AddCurve(title, ind2, Color.OrangeRed, SymbolType.Default);
Indpane2.AxisChange();
myTabPage.Controls.Add(zed);
tabControl1.TabPages.Add(myTabPage);
IndCurve2.Line.IsVisible = true;
IndCurve2.Line.Width = 2.0F;
zed.Invalidate();
zed.Refresh();
}
一个简单的逻辑错误。 zedX和zedY的长度必须仅为thisbin.IndLists长度的一半,因为您可以交替分配值。 因此,其余曲线阵列仍为零,因此曲线的最后点为[0,0]。
因此,您必须这样做:
double[] zedX = new double[thisbin.IndLists[i].Count()/2];
double[] zedY = new double[thisbin.IndLists[i].Count()/2];
代替这个:
double[] zedX = new double[thisbin.IndLists[i].Count()];
double[] zedY = new double[thisbin.IndLists[i].Count()];`
