0.1 in logarithmic mode

[Nati]

Hi,

sorry for the small image.
the question is marked in circle. when using logarithmic mode, the 0.1 value on the Y axis is located below the X axis level.
is there a way to make this 0.1 value appears on the same level as X axis?
thanks

Hello Nati,
I couldn't reproduce your problem here, using last version of TeeChartVCL and next code:

Code: Select all

uses Series;
procedure TForm2.FormCreate(Sender: TObject);
var Series1:TLineSeries;
    i:Integer;
begin
     Chart1.View3D:=False;
     Series1 := TLineSeries.Create(self);
     Chart1.AddSeries(Series1);
     for i := 0 to 20 do
     begin
      Series1.AddXY(i,2.0E-3*(5*i-50)*(2*i-10)+5);
     end;
     Chart1.Axes.Left.Logarithmic:=True;
     Chart1.Axes.Left.Increment:=1;
end;

Could you tell us if your problem with label axis, appears using previous code? If previous code doesn't works as you want, please modifies it so we can help you find a good solution for you.

Thanks,

hi

first things first: im using version 8.05.50522
in my project, when i added the line: Chart1.Axes.Left.Increment:=1; (before it was 0) then 0(zero) was at X axis level but the Y axis wasn't in the way we expect it to be, we want it to show 1, 10, 100, 1000... (just like it does when Chart1.Axes.Left.Increment := 0) - see attached (loga2.jpg), the -0.1 value is gone which is good but the values on Y axis lost the 1,10,100,1000 sequence

change your code to make a graph with values around 1, 10, 100, 1000 etc... and Chart1.Axes.Left.Increment:=0 (zero), you will see the -0.1 value below the X axis just like in the image i posted in my first topic - i also attached a new image here where you can see the Y axis values and the -0.1 value below the X axis

thanks

hi

is there an update on this issue?
thanks

Hello Nati,

Sorry for the delay. I have made a new code using values from 0.01 to 1.0E+5:

Code: Select all

uses Series;
procedure TForm2.FormCreate(Sender: TObject);
var Series1:TLineSeries;
    i:Integer;
begin
     Chart1.View3D:=False;
     Series1 := TLineSeries.Create(self);
     Chart1.AddSeries(Series1);
    with  Series1 do
    begin
          AddY(1.0E-3);
          AddY(1.0E-2);
          AddY(1.0E-1);
          AddY(1.0E+1);
          AddY(1.0E+2);
          AddY(1.0E+3);
          AddY(1.0E+4);
          AddY(1.0E+5);
    end;
     Chart1.Axes.Left.Logarithmic:=True;
end;

And I have checked that in last version 8.07 it works fine as show in next image:

So, I recommend you download last version 8 of TeeChartVCL and check again if your problem persist.

I hope will help.

Thanks,

hi

i downloaded 8.07 but it seems to fail to connect to the internet to check my license/password
it asks twice how to connect to the internet, i tried both direct and proxy but both failed and then it says that the license/password is incorrect so im not sure if it fails because it can't connect to the internet or because it thinks the license/password are wrong, needless to say that i enter the same credentials as i do when logging in to this forum.

what am i missing? is there an offline way to install the new version?
thanks

Hello Nati

By default the activation is done via internet and it will fail if you don't have internet connection or a firewall blocks the installer access to the internet. Anyway, you can write an e-mail Sales Dept. at sales at steema dot com. providing the key the installer generated to register the product manually if the installer fails to conect to the internet and prompts you to do so.

Thanks,

hi

after fighting the latest version installation process, i managed to install it but the same happens. i show you an image (of bar series) with the problem, you used a different kind of graph, not sure why,
so 2 things:
1) please use a bar series!
2) if you still dont see the problem on your side, please attach your demo so i can work on it and show you the problem.

thanks

Hello Nati,

I have done your suggestion and I have changed TLineSeries to TBarSeries:

Code: Select all

uses Series;
procedure TForm2.FormCreate(Sender: TObject);
var Series1:TBarSeries;
    i:Integer;
begin
     Chart1.View3D:=False;
     Series1 := TBarSeries.Create(self);
     Chart1.AddSeries(Series1);
    with  Series1 do
    begin
          AddY(1.0E-3);
          AddY(1.0E-2);
          AddY(1.0E-1);
          AddY(1.0E+1);
          AddY(1.0E+2);
          AddY(1.0E+3);
          AddY(1.0E+4);
          AddY(1.0E+5);
    end;
     Chart1.Axes.Left.Logarithmic:=True;
end;

And I get next result:

Could you confirm us, that your problem is the same of above image? If it isn't the same, please modify previous code, because we can reproduce it here.

Thanks,
