Hi,

I am new to coding in c# and not very good. I basically have a simple line chart with which shows a stock price over the course of a couple of days.

On the y-axis I have the price. On the x-axis I have the date & time. However on the x-axis at every interval the date & time is shown but it is very hard to read what I would like is to be able to display the x-axis like the in the picture attached. I have no idea how to do this.

Any help would be great.

Thanks,

Mark

Here is an example... Give that a try and let me know if that gets you where you need to be.

            List<TestObject> bonds = LoadTestObjects(this.dropPortfolios.SelectedValue.Trim()).ToList();

            if (bonds != null && bonds.Count > 0)
            {
                this.Chart1.ChartAreas["ChartArea1"].AxisX.IsMarginVisible = true;
                this.Chart1.ChartAreas["ChartArea1"].AxisY.Title = "Duration";
                this.Chart1.ChartAreas["ChartArea1"].AxisX.Title = "Scenario";
                this.Chart1.ChartAreas["ChartArea1"].ShadowOffset = 2;

                this.Chart1.Legends["Default"].BackColor = System.Drawing.Color.White;
                this.Chart1.Legends["Default"].BorderColor = System.Drawing.Color.Black;
                this.Chart1.Legends["Default"].BorderWidth = 0;
                this.Chart1.Legends["Default"].Docking = System.Web.UI.DataVisualization.Charting.Docking.Bottom;
                this.Chart1.Legends["Default"].Alignment = System.Drawing.StringAlignment.Center;
                this.Chart1.Legends["Default"].LegendStyle = System.Web.UI.DataVisualization.Charting.LegendStyle.Column;
                this.Chart1.Legends.Add(new System.Web.UI.DataVisualization.Charting.Legend("MainLegend"));
                this.Chart1.Legends["Default"].IsEquallySpacedItems = true;


                foreach (Domain.VBond bond in bonds)
                {
                    System.Web.UI.DataVisualization.Charting.Series series = new System.Web.UI.DataVisualization.Charting.Series(bond.Sector);
                    series.ChartType = System.Web.UI.DataVisualization.Charting.SeriesChartType.Line;
                    series.MarkerStyle = System.Web.UI.DataVisualization.Charting.MarkerStyle.Circle;
                    series.Points.AddY(Convert.ToDouble(bond.Number1));
                    series.Points.AddY(Convert.ToDouble(bond.Number2));
                    series.Points.AddY(Convert.ToDouble(bond.Number3));
                    series.Points.AddY(Convert.ToDouble(bond.Number4));
                    series.Points.AddY(Convert.ToDouble(bond.Number5));

                    series.Points[0].AxisLabel = "-200";
                    series.Points[1].AxisLabel = "-100";
                    series.Points[2].AxisLabel = "Base";
                    series.Points[3].AxisLabel = "+100";
                    series.Points[4].AxisLabel = "+200";
                    series.Legend = "MainLegend";
                    series.BorderWidth = 3;
                    this.Chart1.Series.Add(series);
                }

Hi binaryevo,

Thanks for the reply. Will try the code as soon as I can, we'r having IT issues today in our office.

Here is the following basic code I have in the form class.

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Windows.Forms.DataVisualization.Charting;
using System.Data.OleDb;
using System.Data.SqlClient;
using System.IO;
namespace WindowsFormsApplication2
{
public partial class Form1 : Form
{
string cn = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=";
string dbPath = @"C:\Blah\";
string[] Pairs = new string[] { "AUDCAD", "AUDCHF", "AUDJPY", "AUDNZD", "AUDUSD", "CADJPY", "CHFJPY", "EURAUD", "EURCAD", "EURCHF", "EURDKK", "EURGBP", "EURJPY", "EURNOK", "EURNZD", "EURSEK", "EURUSD", "GBPAUD", "GBPCAD", "GBPCHF", "GBPJPY", "GBPNZD", "GBPUSD", "NZDJPY", "NZDUSD", "USDCAD", "USDCHF", "USDDKK", "USDHKD", "USDJPY", "USDNOK", "USDSEK", "USDSGD", "USDZAR" };
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
int i;
// set the date & time pickers
this.dateTimePickerFrom.Format = DateTimePickerFormat.Custom;
this.dateTimePickerFrom.CustomFormat = "dd/MM/yyyy HH:mm:ss";
this.dateTimePickerTo.Format = DateTimePickerFormat.Custom;
this.dateTimePickerTo.CustomFormat = "dd/MM/yyyy HH:mm:ss";
// temp
this.dateTimePickerFrom.Value = new DateTime(2010, 1, 1);
this.dateTimePickerTo.Value = new DateTime(2010, 3, 31);
// set the combo box list & start it at EURUSD
for (i = 0; i < Pairs.Length; i++)
{
this.cmbPairs.Items.Add(Pairs[i]);
}
cmbPairs.Text = "EURUSD";
chartFXPair.ChartAreas.Clear();
chartFXPair.Series.Clear();
}
private void LoadDataPointIntoGraph(DateTime dtFrom, DateTime dtTo, string FXPair)
{
double minPrice = 999, maxPrice ; 
chartFXPair.ChartAreas.Clear();
chartFXPair.Series.Clear();
chartFXPair.Titles.Clear();
ChartArea cArea = new ChartArea("Area");
Series seriesPrice = new Series("PriceData");
chartFXPair.Titles.Add(FXPair);
seriesPrice.ChartType = SeriesChartType.Line;
chartFXPair.Series.Add(seriesPrice);
OleDbConnection dbConnection = new OleDbConnection(cn + dbPath + "dbFX_1Min_db.mdb");
dbConnection.Open();
OleDbCommand SQLQuery = dbConnection.CreateCommand();
SQLQuery.CommandText = @"SELECT [Date]+[Time] AS DateAndTime, 
Round(([Close_B]+[Close_A])/2,5) AS Close_Mid
FROM " + FXPair +
" WHERE ((([Date])>=#" + dtFrom.Date + @"# 
And ([Date])<=#" + dtTo.Date + @"#) 
AND (([Time])>=#12/30/1899 " + dtFrom.Hour + ":" + dtFrom.Minute + ":" + dtFrom.Second + @"# 
And ([Time])<=#12/30/1899 " + dtTo.Hour + ":" + dtTo.Minute + ":" + dtTo.Second + @"#))
ORDER BY [Date], [Time];"; 
OleDbDataReader PriceReader = SQLQuery.ExecuteReader();
if (PriceReader.HasRows)
{
while (PriceReader.Read())
{
if ((Double)PriceReader["Close_Mid"] > maxPrice)
maxPrice = (Double)PriceReader["Close_Mid"];
else if ((Double)PriceReader["Close_Mid"] < minPrice)
minPrice = (Double)PriceReader["Close_Mid"];
seriesPrice.Points.AddXY((DateTime)PriceReader["DateAndTime"], (Double)PriceReader["Close_Mid"]);
}
}
chartFXPair.ChartAreas.Add(cArea);
cArea.AxisY.Minimum = minPrice;
cArea.AxisY.Maximum = maxPrice;
PriceReader.Close();
dbConnection.Close();
}
private void buttPlot_Click(object sender, EventArgs e)

string txt;

Just to be clear I've attached another picture as after re-reading my first post I do not think it was excatly clear as to what I want.

If you open the word document you will see a snap shot of a chart. On the x-axis you will see the time ie 12:00, 14:00. Beneath the time values you will see the actual date 06 Sep 2011. When the time value then moves past midnight the date value 07 Sep 2011 is displayed.

To me it appears there has to be two 'labels' for the x-axis to do this. If you carry scrolling on the chart as the time changes so does the date beneath the time values to the correct date. This is what I am trying to replicate.

Again thanks for any help!
