unichart series title

[jahlxx]

Hi.

How can I change the serie title of a chart in run time?

Tested on bar series, but don't work. The title doesn't change, is allways the title defined at design time.

Thanks.

Hello,

Which build are you using?

Can you give the code you use?

[jahlxx]

build 1454

my code is simple: series3.title := 'my title';

Can you try this approach for now?

1. 

uses ... uniStrUtils;

2. procedure SetTitle(AUniBarSeries: TUniBarSeries; ATitle: string);

procedure TMainForm.SetTitle(AUniBarSeries: TUniBarSeries; ATitle: string);
var
  I: Integer;
  Titles: string;
begin
  if (ATitle<>'')and(AUniBarSeries.Title<>ATitle) then
  begin
    AUniBarSeries.Title := ATitle;
    for I := 0 to AUniBarSeries.Parent.SeriesList.Count-1 do
      Titles := Titles + '"' + (AUniBarSeries.Parent.SeriesList[I] as TUniBarSeries).Title + '",';

    Titles := RemoveTrailingChar(Titles, ',');
    with AUniBarSeries.Parent.JSInterface do
      JSCall('chart.series[0].setTitle', [JSArray(Titles)]);
  end;

end;

3. Use

SetTitle(Series3, 'newTitle');

Ok. It works, Thanks. I think that is a extrange for an easy task, but works.

And what about this kind of labels? (see image)

 

This is done with Chart.js. Is possible with unichart? I prefer don't use external utils is I can do them with standard components.

Thanks.

They are already implemented.

UniChart -> Axes -> AxisA -> Title, AxisB -> Title

UniChart -> Title -> Text

 

[jahlxx]

Ok.

Title is shown. Not like in Chart.js, but is OK for me.

AxisA is shown, but unformatted:

 

AxisB, is not shown.

 

My code is:

   UniChart3.Axes.AxisA.Title := 'Test Vertical';
   UniChart3.Axes.AxisB.Title := 'Test Horizontal';

Can you make a testcase for reproduce!?

[jahlxx]

Ok Works.

The problem is calling to SetTitle procedure. When call, the behaviour is as explained before. If don't call to that procedure, AxisA and AxisB are shown.

I couldn't reproduce this behavior. Works for me.

  ..
  with AUniBarSeries.Parent.JSInterface do
    //JSCall('chart.series[0].setTitle', [JSArray(Titles)]);
    JSCode('try {'#1'.chart.series[0].setTitle(['+ Titles +'])} catch(err){};');
  ...

 

[jahlxx]

Ok, Thanks.

So complicated for a simple task.

Should be:

series3.title := 'my title';

I do not argue with you, just gave a temporary solution. 

[jahlxx]

Sorry!!

Maybe you didn't understand me or I did't explain ok.

Thanks for your temporary solution. I meant that the solution should be as simple as assign text to the property of the element. That's all. Perhaps is a bug og UniGUI that will be corrected in later builds.

Sorry again friend.

No, really everything is OK!

Sorry, you're right, we need to do this using the property. I will open a ticket in the support portal.
