Hi all,
I'm having an error in Teechart 2011 on Delphi Xe.
I have 2 pc with windows 7, one with font at 100% (windows -> control panel -> Appearance and Personalization -> Display setting -> Font Size) and one with 125%.

To avoid the problem of wrong font scaling, i have disabled scaling in my form (Scaled := False). All components respect this options, and many charts in my form also respect this, but not all.

I have 2 charts with Point Series, with series created dinamically (the other charts that work have static series), and with this all my Marks are proportioned wrong in 125%.

Have tryed also to set Serie1.marks.font.pitch := fpFixed, or set Serie1.marks.font.pixelperinch := 96, but nothing change, always wrong.

Is there an option that i miss that can solve this problem?

Hi sicorspa,

I've tried it with Win 7 x64 and the chart texts seem to behave as the regular TLabel. Find an example attached. If you still have problems with it, don't hesitate to let us know.

take your project and set form.scaled to FALSE

i don't want that the marks text is scaled

if you try with scaled to false and try your application with 100% font size (windows 7 option, in windows xp 96dpi) and 125% font size (windows 7 option, in windows xp 120dpi) you will see that the marks text will be scaled up, from 8 pixel height to 10 pixel height.

The form itself isn't scaling, like you can see from the label "My custom label text"

tryed also setting marks.font.pitch := fpFixed, or set marks.font.pixelperinch := 96 but marks are always scaling.

With circle series for example this doens't happen

Hi sicorspa,

Adding this to the project above: still gives me a bigger label text in 125% than in 100% mode:

You don't undestand.

As I have say in all my posts, I DON'T WANT FONT SCALING, SO I HAVE SET IT TO DISABLE IN THE FORM.

THE PROBLEM IS THAT TEECHART SCALE THE MARKS IGNORING THAT SETTINGS

Try setting Form.Scaled := FALSE;

The Point Series Scale the marks anyway

Hi,

I haven't probably explained myself clearly enough.
In my first reply I forgot setting "Form1.Scaled:=false;".
However, I added it in the next reply and, as you can see in the first picture, all the texts seem to be bigger, both the TeeChart texts (axes labels, marks, legend items and title) and non TeeChart related texts (the label "M y custom label text", an the form caption "Form1").
So I'm not sure to be able to reproduce the point:

With Form1.Scaled:=false, no component seem to be respecting this option for us here in two different machines. If the attached exe gives you a different result than the shown in the images in the zip, there must be something different in our machines and yours.

in your attachments there is form.scaled to true

setting it to false give me this



as you see with 120dpi the label "My custom label text" is alway the same dimension as 96dpi, the marks and the legend of the chart instead grow.

I use Delphi XE and teechart pro 2011

If your label "My custom label text" grow in dimension with 120dpi (or 125% in windows 7 style) is because you haven't set form.scaled to false

it's a standard function in delphi and have alvway worked in all versions, so it's not normal that in your system this option don't work



set it in design time, not runtime

Hi,

This seemed to make the difference for me here.
I've added to the wish list the possibility to add a Scaled property or a ScaleBy function in a future release (TV52016158).
Thanks for reporting and explaining it.

Thanks for your support

anyway i think it's also a bug that teechart marks don't respect font scaling disabled in point series (it's not so for vertical bar series and pie series for example)
