Hi. It should give you similar, but not the same look. The same could be achieved using MoveTo3D and LineTo3D methods. To get a true 3d feel and look I'd stick with Cylinder method. Using it it'd be a lot easier to control the z coordinate (concentration). For example, the following code will draw a...

Hi. Hmm... I don't think this drawing method will mimic true 3d scatter plot. The Cylinder canvas method will draw a vertical or horizontal cylinder using Left,Right,Top,Bottom as bounds in x-y (2d projection) plane and Z0 and Z1 as bounds in z plane. That is, the Z0 and Z1 (if not equal) define the...

Hi. take it you are saying to create another table, insert the values in it then Yes, and then connect it to TDBGrid. Or if you want a more generic solution, create a customized datasource for table and then connect the table it. I want this to be done automatically Still, you can calculate values, ...

Hi.

Try using TPoint3DSeries. It more less does exactly what you need (gives you control over individual point z=z(x,y) coordinate).

Hi.

Hmm... Try setting Series2.Marks.Visible property to true: If this doesn't work, let me know and I'll prepare a sample test application (D2006) for you.

Hi.

Yes, sure, this can be done. Check the following example in TeeChart demo:
All Features -> Axes -> Opaque zones
or
All Features -> Axes -> Multiple at runtime.

Hi.

Why don't you simply create a temporary table, copy values in it and finally connect this table directly to TDBGrid using the same schema as for any other dataset ?

Hi. I think the problem is how you use ValueIndex parameter in OnGetMarkText event. In this event ValueIndex is constant parameter and should not be used as variable in for loop. You should figure out another way to "connect" failure to point ValueIndex (index) parameter. Something like this: if (Op...

Hi. The following example uses series GetSeriesMarj event to customize individual mark text: public Form1() { InitializeComponent(); line1.Marks.Visible = true; line1.FillSampleValues(); } private void line1_GetSeriesMark(Steema.TeeChart.Styles.Series series, Steema.TeeChart.Styles.GetSeriesMarkEven...

Hi. How does it work? Well, you're using the TChartSeries OnGetMarkText event, together with failure series values, to "filter" which point marks you want to mark as "failed". Something like this: // Enable, disable failure filter procedure TForm1.CheckBox1Clicked(Sender: TObject); begin if (CheckBo...

Hi, Ricky. Another way to have vertical axis at specific x position (in your case 0.0) is to use the following code: ... horizBar1.Add(-5); horizBar1.Add(5); horizBar1.Add(-2); horizBar1.Add(-1); horizBar1.GetVertAxis.Visible = false; ... private void tChart2_BeforeDrawSeries(object sender, Steema.T...

Hi, David. Yes, several ways to do it. I'd use TChartSeries OnGetMarkText event to show/hide individual mark text. Something like this: procedure TForm1.Series2GetMarkText(Sender: TChartSeries; ValueIndex: Integer; var MarkText: string); begin if Sender.MandatoryValueList[ValueIndex] >0 then MarkTex...

Hi. To add a chart tool to specific chart, do the following: 1. Add a TChart on the form. 2. Select tChart with left mouse button. 3) Press right mouse button to bring up chart editor. 4) Select the "Tools" tab. 5) Press the "+" sign button 6) Select "Axis" tab 7) Double click the "color line" tool ...

Hi. But will this work for any generic series? i.e. Lines, Bars, etc? I know I can cast it as a Bar type, but will it give the same general behaviour if the actual object is of a different type. Not all series have border property so this can't be generic (i.e. introduced as public property for base...

I'm glad it turned out ok.
