How to decrease distance between ticks? I want to place candles more closely.
And i cannot find any property in LinearAxis XAxis that respond for distance.
Code:
namespace WpfApplication20
{
/// <summary>
/// Interaction logic for MainWindow.xaml
/// </summary>
///
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
DataContext = new PlotClass();
}
}
public class PlotClass
{
public PlotModel PlotModel { get; set; }
public PlotClass()
{
Random rnd = new Random();
PlotModel = new PlotModel();
LineSeries LS = new LineSeries();
LinearAxis XAxis = new LinearAxis
{
Position = AxisPosition.Bottom,
MinorStep=1,
MajorStep=1
};
LinearAxis YAxis = new LinearAxis()
{
Position = AxisPosition.Left
};
for (int i=0;i<10;i++)
{
LS.Points.Add(new DataPoint(i,rnd.Next(1,10)));
}
PlotModel.Axes.Add(YAxis);
PlotModel.Axes.Add(XAxis);
PlotModel.Series.Add(LS);
ChangeToCandles();
WhatTypeOfSeries();
}
public void ChangeToCandles()
{
Random rnd = new Random();
PlotModel.Series.Clear();
CandleStickSeries CSS = new CandleStickSeries();
for (int i = 0; i < 10;i++ )
{
CSS.Items.Add(new HighLowItem { X = i, Close = rnd.NextDouble(), High = rnd.NextDouble(), Low = rnd.NextDouble(), Open = rnd.NextDouble() });
}
PlotModel.Series.Add(CSS);
}
public void WhatTypeOfSeries()
{
var temp = PlotModel.Series[0].GetType();
Console.WriteLine(temp);
}
}
}
xaml:
<Grid>
<oxy:Plot Model="{Binding PlotModel}"/>
</Grid>
Try zooming:
XAxis.Zoom(-5, 15);
EDIT>>>>
You have a for loop from 0 to 10, you just have to add some adjust values. For that limits for being more generic:
int lowerIndex = 0;
int upperIndex = 10;
int zoomValue = 5;
for (int i=lowerIndex;i<upperIndex;i++)
{
LS.Points.Add(new DataPoint(i,rnd.Next(1,10)));
}
XAxis.Zoom(lowerIndex-zoomValue, upperIndex+zoomValue);
Try to play with CandleStickSeries.CandleWidth property:
If it is set to 1, then there will be no space between candles.
If it is set to value > 1, then candles will overlap.
If it is set to value < 1, then there will be a gap between candles. The smaller value, the bigger gap.

I am trying to make a simple five in a row (gomoku) game for two players using windows forms and c#. I put a picturebox with a picture and stretched it out on the form. Now I want to put labels at all the intersections on the picture board so a user can click them and change their background color to black or white.
How can I make the labels created clickable on the form?
public partial class Form1 : Form
{
int labelCount = 0;
int iteration = 0;
public Form1()
{
InitializeComponent();
Label[] board = new Label[361];
for (int i = 0; i < 361; i++)
{
board[i] = new Label
{
Name = "label" + i,
Height = 55,
Width = 55,
MinimumSize = new Size(55, 55),
Text = "label " + i
};
}
int x = 0;
int y = 0;
foreach (var Label in board)
{
if (x >= 580)
{
x = 0;
y = y + Label.Height + 55;
}
Label.Location = new Point(x, y);
this.Controls.Add(Label);
x += Label.Width;
}
}
}
Should I make a one-dimensional [361] or two-dimensional array[{A,1}, {A,2}....{D,1}] to easily check for a winner? How can I connect it to the created labels so the array data corresponds to the objects on the board?
Well Sorry If don`t understand your question. For the Q.1 to add 361 labels you can try the code below. I hope it will help you.
public int x = 0;
public int y = 0;
private Label[] moku = new Label[361];
private void Form1_Load(object sender, EventArgs e)
{
try
{
for (int i = 0; i < 361; i++)
{
moku[i] = new Label();
moku[i].Parent = pictureBox1;//make the picturebox parent
moku[i].Location = new Point(x, y);
moku[i].Text = "O";
moku[i].Name = "moku" + i;
moku[i].BackColor = Color.Transparent;
pictureBox1.Controls.Add(moku[i]);
y += 55;
if (y >= 361) { x += 55; y = 0; x+=55; }
}
}catch(Exception er)
{
MessageBox.Show(er.ToString());
}
}
I prefer using a 2D array because it's easier if you want to check the surrounding boxes.
Form design:
Full source:
using System;
using System.Drawing;
using System.Windows.Forms;
namespace WindowsFormsApplication6
{
public enum Player
{
Empty = 0,
White,
Black
}
public partial class Form1 : Form
{
// initialize board of 5x5
private Player[,] board = new Player[5, 5];
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
DrawBoard();
}
private void DrawBoard()
{
for (var i = 0; i <= board.GetUpperBound(0); i++)
{
for (var j = 0; j <= board.GetUpperBound(1); j++)
{
// for name and text
var name = string.Format("{0}, {1}", i, j);
var label = new Label()
{
Name = name, // name of label
Size = new Size(55, 55),
BorderStyle = BorderStyle.FixedSingle,
Location = new Point(i * 55, j * 55), // location depends on iteration
Text = name
};
label.Click += ClickLabel; // subscribe the Click event handler
pictureBox1.Controls.Add(label); // add label to a container
}
}
}
// this event handler will handle all the labels click event
private void ClickLabel(object sender, EventArgs e)
{
var label = (Label)sender; // this is the label that you click
var x = Convert.ToInt32(label.Name.Split(',')[0]);
var y = Convert.ToInt32(label.Name.Split(',')[1]);
// change the color
if (radPlayerBlack.Checked)
{
// Player Black
label.ForeColor = Color.White;
label.BackColor = Color.Black;
board[x, y] = Player.Black;
}
else
{
// Player White
label.ForeColor = Color.Black;
label.BackColor = Color.White;
board[x, y] = Player.White;
}
}
}
}
You can check the value of the 2D array for black or white. Here's the value when I QuickWatch it in Visual Studio.
I want that all my actions for drawing graph were in my control, inherited from Canvas. But window don't display MyCanvas. I don't know why.
class MyCanvas : Canvas
{
private Double XTimeScale;
private Double YAmpSacle;
private Double YTopLimit;
private Double YBotLimit;
private List<Point> DotsGraph;
public MyCanvas(Double XTimeScale,
Double YAmpSacle,
Double YTopLimit,
Double YBotLimit)
{
this.XTimeScale = XTimeScale;
this.YAmpSacle = YAmpSacle;
this.YTopLimit = YTopLimit;
this.YBotLimit = YBotLimit;
this.Height = (YTopLimit + YBotLimit);
}
public List<Line> DrawNet(Double Width, Double Height)
{
List<Line> temp = new List<Line>();
SolidColorBrush brush = new SolidColorBrush();
brush.Color = Colors.Gray;
for (int i = 0; i < Width; i+= 10)
{
Line Y = new Line();
Y.Stroke = brush;
Y.StrokeThickness = 1;
Y.Y1 = 0;
Y.Y2 = Height;
Y.X1 = i;
Y.X2 = i;
temp.Add(Y);
}
for (int j = 0; j < Height; j += 10)
{
Line X = new Line();
X.Stroke = brush;
X.StrokeThickness = 1;
X.X1 = 0;
X.X2 = Width;
X.Y1 = j;
X.Y2 = j;
temp.Add(X);
}
foreach (var t in temp)
this.Children.Add(t);
return temp;
}
}
And the class of windows where MyCanvas should be displayed. I added it to Grid:
public partial class ShowCanvas : Window
{
public ShowCanvas()
{
InitializeComponent();
MyCanvas EAP = new MyCanvas(300, 300, 300, 300);
Base.Children.Add(EAP); // Base is Grid on window ShowCanvas
}
}
Your window did display your canvas, but your canvas didn't have any children. Call DrawNet method.
You can use an open-source program called "Snoop" to navigate through the visual tree and see properties of visuals
Is it possible to have a different marker style for ranges among (XY-Axis) values ? For example. The marker style is shown in steel blue color here, Can I have markers above 15 and below 13 to show another color ?
Display:
Oxyplot has both a TwoColorLineSeries and a ThreeColorLineSeries
Here is an example with the ThreeColorLineSeries
public class MainViewModel
{
public MainViewModel()
{
Model = new PlotModel
{
Title = "Colouring example"
};
var series = new ThreeColorLineSeries();
// Random data
var rand = new Random();
var x = 0;
while (x < 50)
{
series.Points.Add(new DataPoint(x, rand.Next(0, 20)));
x+=1;
}
// Colour limits
series.LimitHi = 14;
series.LimitLo = 7;
// Colours
series.Color = OxyColor.FromRgb(255,0,0);
series.ColorHi = OxyColor.FromRgb(0,255,0);
series.ColorLo = OxyColor.FromRgb(0,0,255);
Model.Series.Add(series);
}
public PlotModel Model { get; set; }
}
I'm trying to move my project from WinForms to WPF, but i couldn't succeed in this. I had a picture box, with a full of lines one after another and i could just use DrawLine(pen,point,point) in a loop. But when i tried to do this by using WPF, i couldn't menage.
This is the code snippet that i've used in WinForms :
for (x = 0; x < X_COORD_END - X_COORD_START; x += 1)
{
System.Drawing.Point point1 = new System.Drawing.Point(x, 30);
System.Drawing.Point point2 = new System.Drawing.Point(x, 60);
e.Graphics.DrawLine(myPen, point1, point2);
}
And the result was :
I've tried to use Line array on WPF, but i gave an error on canvas.Children.Add line. Now i'm trying to use collection of points, but i can't arrange points as i want to. Here is what i've tried :
private void DrawLine(Point[] points)
{
Polyline line = new Polyline();
PointCollection collection = new PointCollection();
foreach (Point p in points)
{
collection.Add(p);
}
line.Points = collection;
line.Stroke = new SolidColorBrush(Colors.Black);
line.StrokeThickness = 20;
scanCanvas.Children.Add(line);
}
for (int counter = 0; counter < 1000; counter++ )
{
points[counter] = new Point(counter, 30);
}
DrawLine(points);
Use Stackpanel for your scenario. I have used a line array, which is similar to the thing which you have done in winforms.
MainWindow.xaml
<Window x:Class="SO.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="525">
<StackPanel x:Name="stackGraphicsArea" Orientation="Horizontal"/>
</Window>
MainWindow.xaml.cs
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
Line[] lines = new Line[1000];
for(int i=0; i<1000;i++)
{
lines[i] = new Line();
lines[i].Stroke = new SolidColorBrush(Colors.Red);
lines[i].StrokeThickness = 5;
lines[i].X1 = 0;
lines[i].X2 = 0;
lines[i].Y1 = 30;
lines[i].Y2 = 20;
}
DrawLines(lines);
}
private void DrawLines(Line[] _lines)
{
foreach (Line _line in _lines)
{
stackGraphicsArea.Children.Add(_line);
}
}
}
Sriman Reddy has answered my question already but i think i should post my own solution too :
private void DrawLine(int x_coord_start, int y_coord_start, int x_coord_end, int thickness, Color color)
{
Random rand = new Random();
for (int x = 0; x < x_coord_end - x_coord_start; x++)
{
double newTop = rand.Next();
Line top = new Line();
top.Stroke = new SolidColorBrush(color);
top.StrokeThickness = x + 1;
top.X1 = x_coord_start + x;
top.Y1 = y_coord_start;
top.X2 = x_coord_start + x;
top.Y2 = y_coord_start + thickness;
Canvas.SetTop(top, 0);
Canvas.SetLeft(top, 0 /*x * top.Width*/);
scanCanvas.Children.Add(top);
}
}
I'm trying to add some ellipces with random positions into my canvas, but i can see them on my canvas. Progmab is compilling quite saccesfull. Code:
for (int i = 0; i < FirefliesCount; ++i)
{
Firefly CurrentFirefly = new Firefly();
CurrentFirefly.Speed = Randomer.Next(1, 3);
CurrentFirefly.Body = new Ellipse();
CurrentFirefly.Body.Margin = new Thickness(Randomer.Next(10, (int)MainCanvas.Width - 10),
Randomer.Next(10, (int)MainCanvas.Height - 10),
0, 0);
CurrentFirefly.Body.Fill = Brushes.Black;
CurrentFirefly.Body.Height = MainCanvas.Height / 4;
CurrentFirefly.Body.Width = 1.5 * CurrentFirefly.Body.Height;
MainCanvas.Children.Add(CurrentFirefly.Body);
}
And Fireflie class:
class Firefly
{
public Ellipse Body { get; set; }
public int Speed { get; set; }
}
Probably you did not set the Width and Height properties of your MainCanvas; then they have the value NaN and therefore you will not see the ellipses.
My suggestion is to use ActualWidth and ActualHeight instead and to delay the adding of the ellipses until the canvas is loaded. Here is an example:
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
MainCanvas.Loaded += MainCanvas_Loaded;
}
void MainCanvas_Loaded(object sender, RoutedEventArgs e)
{
Init();
}
private void Init()
{
const int FirefliesCount = 100;
Random Randomer = new Random();
for (int i = 0; i < FirefliesCount; ++i)
{
Firefly CurrentFirefly = new Firefly();
CurrentFirefly.Speed = Randomer.Next(1, 3);
CurrentFirefly.Body = new Ellipse();
CurrentFirefly.Body.Margin = new Thickness(Randomer.Next(10, (int)MainCanvas.ActualWidth - 10),
Randomer.Next(10, (int)MainCanvas.ActualHeight - 10),
0, 0);
CurrentFirefly.Body.Fill = Brushes.Black;
CurrentFirefly.Body.Height = MainCanvas.ActualHeight / 4;
CurrentFirefly.Body.Width = 1.5 * CurrentFirefly.Body.Height;
MainCanvas.Children.Add(CurrentFirefly.Body);
}
}
}
The corresponding xaml file looks like this:
<Window x:Class="WpfApplication7.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
