Need help in BoxPlot
Posted: Thu Aug 13, 2009 9:17 am
I want to select multiple box plot points and then exclude and include according to the selection.
How to acheive this.
How to acheive this.
I found a solution for you and you can use a similar code for this in your application. Please see next code and check works as you want:
InitializeChart:
Code: Select all
public Form1()
{
InitializeComponent();
InitializeChart();
}
bool[] Selected1;
bool[] Selected2;
bool[] Selected3;
bool drawrectangle;
Steema.TeeChart.Styles.Box box1, box2, box3;
Rectangle rect;
private void InitializeChart()
{
//-----------------INITIALIZE CHART WITH BOXPLOT-----------------------//
box1 = new Steema.TeeChart.Styles.Box(tChart1.Chart);
box2 = new Steema.TeeChart.Styles.Box(tChart1.Chart);
box3 = new Steema.TeeChart.Styles.Box(tChart1.Chart);
tChart1.Aspect.View3D = false;
tChart1.Aspect.ClipPoints = true;
drawrectangle = false;
box1.FillSampleValues();
box2.FillSampleValues();
box3.FillSampleValues();
box1.Position = 1;
box2.Position = 2;
box3.Position = 3;
box1.Color = Color.Red;
box2.Color = Color.Yellow;
box3.Color = Color.Green;
box1.Title = "Box1";
box2.Title = "Box2";
box3.Title = "Box3";
box1.Pointer.Visible = true;
box2.Pointer.Visible = true;
box3.Pointer.Visible = true;
Selected1 = new bool[box1.Count];
Selected2 = new bool[box2.Count];
Selected3 = new bool[box3.Count];
tChart1.Panning.MouseButton = MouseButtons.Middle;
tChart1.MouseMove += new MouseEventHandler(tChart1_MouseMove);
tChart1.MouseUp += new MouseEventHandler(tChart1_MouseUp);
tChart1.MouseDown += new MouseEventHandler(tChart1_MouseDown);
tChart1.AfterDraw += new Steema.TeeChart.PaintChartEventHandler(tChart1_AfterDraw);
box1.GetPointerStyle += new Steema.TeeChart.Styles.CustomPoint.GetPointerStyleEventHandler(box1_GetPointerStyle);
box2.GetPointerStyle += new Steema.TeeChart.Styles.CustomPoint.GetPointerStyleEventHandler(box1_GetPointerStyle);
box3.GetPointerStyle += new Steema.TeeChart.Styles.CustomPoint.GetPointerStyleEventHandler(box1_GetPointerStyle);
tChart1.Draw();
ResetCoords();
}
Event of the project:
Code: Select all
void tChart1_AfterDraw(object sender, Steema.TeeChart.Drawing.Graphics3D g)
{
if ((X0 != -1) && (Y0 != -1))
{
if (drawrectangle)
{
g.Brush.Visible = false;
g.Pen.Color = Color.Black;
g.Rectangle(X0, Y0, X1, Y1);
}
}
for (int i = 0; i < Selected1.Length; i++)
{
for (int j = 0; j < tChart1.Series.Count; j++)
{
Point p = new Point(tChart1[j].CalcXPos(i), tChart1[j].CalcYPos(i));
Rectangle rect1 = new Rectangle(p.X - box1.Pointer.HorizSize - 5, p.Y - box1.Pointer.VertSize - 5, (box1.Pointer.HorizSize + 5) * 2, (box1.Pointer.VertSize + 5) * 2);
