XE5 Update 2 ambiguity TGRectF

Hi, Just got around to compiling an app under TChart 2013.09.131119 and XE5 update 2 (hot fix 1,2,3). As discussed in a previous thread I'm getting the abiguity error when compiling as follows :- [bcc32 Error] VCLTee.TeeGDIPlus.hpp(73): E2015 Ambiguity between 'TGPRectF' and 'Advgdip::TGPRectF' I ha...

Re: Statistics tool

Hi Narcis, I ended up adding another point series to the chart that has the statistics tool connected but series is not displayed. It adds in 2,737,145 points in around 8 seconds and displays the graphs in that time as well. However calling ChartTool3->Statistics(MemoInfo->Lines); on the two graphs ...

Statistics tool

Hello,

I was trying the Statistics tool on a bar graph series which shows a frequency distribution. In this case the information of interest is actually in the x-axis rather than the y-axis.

Is it possible to get the statistics for the x-axis ?

Re: Can't get marks to display

I have found the issue relates not to the above code example but when I try to change the mark values later on in the code. It seems this aspect of the code no longer works, for example :- point_->Marks->Item[index_]->Font->Color = color_; or point_->Marks->Item[index_]->Visible = true; Accessing an...

Re: TAnnotationTool disappears

I have found the issue is muPercent.

If I change that to pixels and set the % values myself it draws correctly.

Looks like a bug to do with muPercent.

Can't get marks to display

Hello, I'm using the latest VCL Beta and I have TPointSeries that gets created dynamically similar to the following :- marks_ = new TPointSeries(graph_); graph_->AddSeries(craneName_); marks_->Title = "Title"; marks_->SeriesColor = clRed; marks_->Pointer->Style = psTriangle; marks_->Pointer->Inflate...

Re: TAnnotationTool disappears

Just to follow on from this, however if I had a second TAnnotationTool and change this values text in the OnTimer() the other TAnnotationTool value text disappears.

arrghh.

Re: TAnnotationTool disappears

Actually just added the following to the Timer1Timer() :=

void __fastcall TForm1::Timer1Timer(TObject *Sender)
{
chartAnno->Text = "why";
chartAnno->Shape->Left = 50;
chartAnno->Shape->Top = 50;
}

and it is drawn correctly. Is there a reason for this ?

Re: TAnnotationTool disappears

I also tried adding Chart1->Tools->Add(chartAnno); turning off GDI+ and a number of other things but no luck.

I'm using the Beta 2013_130920

TAnnotationTool disappears

Hi, I must be missing something obvious here. This used to work so not sure what I'm doing wrong. I create a TAnnotationTool in the FormShow() and then update it from a OnTimer() event. When I update it in the OnTimer it disappears ? Code looks like this :- void __fastcall TForm1::FormShow(TObject *...

Code to change to GDI

Hello,

I was wondering if you can tell me the code needed in C++ to change the render type from GDI+ to GDI ?

I can change this through the editor but was wanting to do this in code as well.

Thanks
