Added a Maker & Text

[pcs_user]

I’m using TeeChart Pro V2016.18.160504
I'm using C++Builder Seattle Update 1
1. I’m looking to put a maker on a Series. A red dot or a dotted white line.
2. I want text as value for the Y side of the chart, is that possible?

Hello,

I’m looking to put a maker on a Series. A red dot or a dotted white line.

You can use a TColorLine for this. Ie in Delphi:

Code: Select all

  with Chart1.Tools.Add(TColorLineTool) as TColorLineTool do
  begin
    Pen.Color:=clWhite;
    Pen.Width:=2;
    Pen.Style:=psDash;
    Axis:=Chart1.Axes.Bottom;
    Value:=123750;
  end;

I want text as value for the Y side of the chart, is that possible?

You can change the Labels Style to talValue. In Delphi:

Code: Select all

  Chart1.Axes.Left.LabelStyle:=talValue;

I’m not familiar with Delphi. Are there any C++ examples?
Thanks.

Hello,

It's not so different:

Code: Select all

#include "TeeTools.hpp"

Code: Select all

  TColorLineTool* ChartTool1 = new TColorLineTool(Chart1);
  Chart1->Tools->Add(ChartTool1);

  ChartTool1->Pen->Color=clWhite;
  ChartTool1->Pen->Width=2;
  ChartTool1->Pen->Style=psDash;
  ChartTool1->Axis=Chart1->Axes->Bottom;
  ChartTool1->Value=123750;

Yeray,
How do I get the location of the marker so I can display the value of Series 1?
Thanks for your help.

Hello,

I'm not sure to understand what is the exact behaviour you are trying to achieve.
Do you know the x value of the vertical line / red dot? Do you want to drag the color line / the red dot? Do you want the color line /the red dot to follow the mouse movement?

Yeray,
I’ll try to clear it up for you.
I don’t know how to get the x value of the vertical white dashed line (TColorLineTool).
I know how to drag the vertical white dashed line.
I want the “y” value from Series1 on the chart when I move the vertical white dashed line so I could display it on the chart.

Hello,

Have you seen the demo at "All features\Welcome !\Chart styles\Standard\Line (Strip)\Interpolating Line series"?
I believe it does pretty much what you are trying to achieve.

The Features Demo is shipped with the binary version.

Hello,
Thanks for your help.

I’ve not seen the demos. I didn’t have them in my download.
Is there a way I could download them?
I have version TeeChart Pro v2016 VCL/FMX. I didn’t know what is a binary version of the program.

Hello,

The binary version is the version without sources, where the packages come precompiled.
This version includes the examples and the documentation. You should find a shortcut to the "New Features Demo" in the TeeChart group in the start menu. Alternatively, you can find the Tee9New*.exe at the "Examples" folder in the TeeChart installation path.
