Cannot get UniCharts to work in C++ Builder 10.4

[Woutero]

I cannot get UniCharts to work in C++ Builder 10.4, target windows 64bit.

 

I have done the following:

 

In Main.h I have

 

class TForm1 : public TUniForm

{

__published:       // IDE-managed Components

               TUniChart *UniChart1;

               TUniButton *UniButton1;

private: // User declarations

public:                  // User declarations

               __fastcall TForm1(TComponent* Owner);

};

//---------------------------------------------------------------------------

TForm1 *Form1(void);

TUniLineSeries *LineSeries;

//---------------------------------------------------------------------------

 

In Main.cpp I have:

 

void __fastcall TForm1::UniButton1Click(TObject *Sender)

{

   int I,Val;

   String Header;

              

   TUniLineSeries *LineSeries = new TUniLineSeries(UniChart1);

   LineSeries->Parent = UniChart1;

 

  for (I=0; I<=11; I++)

  {

               Header = IntToStr(2000 + I);

 

               Val = Random(100) + 50;

               LineSeries->Add(Val, Header);

  }

 

}

 

Similar code in Delphi 10.4 worked fine, but not in C++ Builder 10.4?

Hello, 

Please specify first, which edition and build of uniGUI are you using? 

[Woutero]

Hi Sherzod!

I'm using uniGUI 1.90 Build 1535

Any suggestions?  Everything works fine in Delphi 10.4 but not in C++ Builder 10.4?

Thanks so much

Not trial?

[Woutero]

Forgot to say that I'm using the Complete Professional version

Done

[Woutero]

Any update? Is there anything wrong with my code? Is this a bug?

Can anyone provide a short C++ example for UniChart that works in C++ Builder?

Thanks in advance

Can you please confirm with which C++ Builder versions the UniChart component works?

I got it to work half way what I need. So at least I know the UniChart component does work with C++ Builder. 

When I  manually add a LineSeries to the UniChart component, then the following code works:

 TUniChartSeries *LineSeries = UniChart1->SeriesList->Series[0] ;  
   LineSeries->Parent = UniChart1;
   LineSeries->Clear();

But I want to create Series[0] dynamically at run time. How do I do that?

 

 

 

[Woutero]

I figured it out, thanks to

The following C++ code works and creates a LineSeries and AreaSeries dynamically, exactly what I want:

  int I;
  TUniLineSeries *LineSeries;
  TUniAreaSeries *AreaSeries;

  LineSeries = new TUniLineSeries(UniChart1);
  LineSeries->Name = "NewLineSeries";
  LineSeries->Parent = UniChart1;
  for (I=1; I<=25; I++)
    LineSeries->Add(Random(1000), IntToStr(I));

  AreaSeries = new TUniAreaSeries(UniChart1);
  AreaSeries->Name = "NewAreaSeries";
  AreaSeries->Parent = UniChart1;
  for (I=1; I<=25; I++)
    AreaSeries->Add(Random(1000), IntToStr(I));

I spoke to soon.

When I put the code above in the UniFormCreate event, then everything works perfectly. But when I move the exact same code to a UniButton1Click event, then nothing happens on the UniChart. This is very weird?

void __fastcall TForm1::UniButton1Click(TObject *Sender)
{

// Same code don't work here

}

[Woutero]

This seems to be a bug. No matter what I do, the same code that works perfectly in the UniformCreate event, does not work when inside a UniButton1Click event.

I have found the following workaround:

I create 2 UniCharts, same size and on top of each other. For the first chart I manually create a LineSeries and for the second chart I manually create an AreaSeries.

Then at run time, depending on which button is pressed, I make UniChart1->Visible = true, UniChart2->Visible = false, and vice versa as needed.

Its a clumsy approach, but the only code that works with  uniGUI 1.90 Build 1535 to allow me to choose at run time between different Series types for a UniChart.

Fore some reason my posts have been ignored for 3 days.  What's going on?

Sherzod I'm not a trial user, I've purchased  a Complete Professional version in 2020, you can check my account

Hello 

I'm sorry, you're not on ignore.

Yes, I know you are a subscriber.

I reported your issue.

We will let you know. 

[Woutero]

Thanks Sherzod

Can you please confirm that setting the Title for a Bar/Line/AreaSeries during run time has been implemented or not?

e.g. BarSeries->Title = "2020";

In uniGUI 1.90 Build 1535, this is a protected member and the above line does not compile?

@Woutero

You can try this approach for now:

Thanks it works
