You could try:
Code: Select all
private void InitializeChart()
{
tChart1.Aspect.View3D = false;
Points point = new Points(tChart1.Chart);
Random rnd = new Random();
for (int i = 0; i < 10; i++)
{
point.Add(i, rnd.Next(10, 100), Convert.ToChar(65 + i) + i.ToString());
}
point.Marks.Visible = true;
point.Marks.Transparent = true;
point.Marks.ArrowLength = 5;
point.Marks.Arrow.Visible = false;
}

You could try something like this:
Code: Select all
List<SeriesMarks> customMarks = new List<SeriesMarks>();
private void InitializeChart()
{
tChart1.Aspect.View3D = false;
Points point = new Points(tChart1.Chart);
Random rnd = new Random();
for (int i = 0; i < 10; i++)
{
point.Add(i, rnd.Next(10, 100), Convert.ToChar(65 + i) + i.ToString());
customMarks.Add(new SeriesMarks(point));
}
point.Pointer.Style = PointerStyles.Circle;
tChart1.AfterDraw +=tChart1_AfterDraw;
}
void tChart1_AfterDraw(object sender, Graphics3D g)
{
for (int i = 0; i < customMarks.Count; i++)
{
customMarks[i].Text = tChart1[0][i].Label;
customMarks[i].Transparent = true;
customMarks[i].Paint(g, Utils.FromLTRB(tChart1[0].CalcXPos(i), tChart1[0].CalcYPos(i), tChart1[0].CalcXPos(i) + 50, tChart1[0].CalcYPos(i) + 50));
}
}

customMarks.Paint(g, Utils.FromLTRB(tChart1[0].CalcXPos(i), tChart1[0].CalcYPos(i), tChart1[0].CalcXPos(i) + 50, tChart1[0].CalcYPos(i) + 50)); // This line is showing error " object reference not to set an instance of object".
I am saving all the information of chart in list object and close the form. my requirement is, when i open the form then data present in list should show in chart. this time above line gives error.

Would you be so kind as to produce a
short, self contained, correct (compilable) example with which I can reproduce this issue here?

private void Chart_AfterDraw(object sender, Steema.TeeChart.Drawing.Graphics3D g)
{
for (int i = 0; i < customMarks.Count; i++)
{
if (customMarks.Series[0].Label == lstCustomPointsSeries.Title)
{
customMarks.Transparent = true;
customMarks.Color = Color.DarkBlue;
customMarks.Text = lstCustomPointsSeries.Title;
customMarks.OnTop = true;
// customMarks.Paint(g, Utils.FromLTRB(lstCustomPointsSeries.CalcXPos(0), lstCustomPointsSeries.CalcYPos(0), lstCustomPointsSeries[i].CalcXPos(0) + 75, lstCustomPointsSeries[i].CalcYPos(0) + 15));
customMarks[i].Paint(g);
}
}
}
When i value increment to more than 0 then line -> customMarks[i].Paint(g); method shows g shows null reference exception.

Using the code example I provided in
this message of mine, I'm afraid I cannot make the code you give me compile. Can you please provide me with some code I can run without having to try and modify it?
Thank you.

I really want to help you, but I cannot help you until you provide me with some code that I can run here without any need for me to modify it.
Could you please send me a full code example, a short, self-contained, correct (compilable) example as I asked you on the 1st of July?
Thank you.

i used
g.TextOut(lstCustomPointsSeries.CalcXPos(0), lstCustomPointsSeries.CalcYPos(0), lstCustomPointsSeries.Title); and problem is resolved.
