Hi,

I'm just learning c# so believe this should not be to hard.

I have a chart on a form which when loaded a new Series called "PriceData" is created, please see the code below.

My problem is I have a class say called Class1 and I am trying to reference the Series called "PriceData" on the chart but cannot.

Any help would be great.

Thanks,

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;

namespace WindowsFormsApplication2
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
chartFXPair.ChartAreas.Clear();
chartFXPair.Series.Clear();
chartFXPair.Titles.Add("Blah");
ChartArea cArea = new ChartArea("Area");
cArea.AxisX.Minimum = 3;
cArea.AxisX.Maximum = 5;
cArea.AxisY.Minimum = 0;
cArea.AxisY.Maximum = 100;
chartFXPair.ChartAreas.Add(cArea);
Series seriesPrice = new Series("PriceData");
seriesPrice.ChartType = SeriesChartType.Line;
seriesPrice.ChartArea = "Area";
chartFXPair.Series.Add(seriesPrice);
seriesPrice.Points.AddXY(1, 50);
seriesPrice.Points.AddXY(2, 25);
seriesPrice.Points.AddXY(3, 70);
seriesPrice.Points.AddXY(4, 40);
}

You are declaring the series inside a private method of the Form class, which is why you can't see it outside of that method.

Declare it as public at the class level and you should be able to reference it from any instance of your form.
