Problem with point and bubble series in version 7

[Mark]

I have upgraded from vesion 5 to 7 using delphi 6. I am missing X axis labels and ticks in my main application of most charts which using bubble or point series which are created at run time. I have reproduced the effect in a tiny 1 chart application

TForm1 = class(TForm)
Chart1: TChart;
procedure FormShow(Sender: TObject);
private
{ Private declarations }
public
{ Public declarations }
end;

var
Form1: TForm1;

implementation

{$R *.dfm}
uses
Series;

procedure TForm1.FormShow(Sender: TObject);
var
Series: TpointSeries;
begin
Series:=TPointSeries.Create(Self);
with Series do
begin
AddXY(0.1,34,'Test1',clteeColor);
AddXY(0.23,44,'Test2',clteeColor);
AddXY(0.41,24,'Test3',clteeColor);
AddXY(0.7,39,'Test4',clteeColor);
AddXY(0.91,24,'Test5',clteeColor);
ParentChart:=Chart1;
GetHorizAxis.LabelStyle:= talValue;
end;

This used to work in version Teechart v5.

If I dont use Labelstyle= the x axis labels are shown as "Test1" etc. What am I doing wrong this should be a simple XY graph. The points come out right, the Y axis is correct but the X axis has no labels, ticks, or grid lines.

Hi,

to show the XLabels you should set the increment to 0.1 (bcos it's less than 1), adding the following line should work fine :

GetHorizAxis.Increment := 0.1;

Why isnt the increment calculated automatically? It is in version 5. It does seem to be in version 7 but only if the increment >1. The data I plot is can have variable ranges depending on which field the user chooses to plot in my application. This means either I have to stick with version 5.02 of teechart which is working correctly or give up using automatic scaling in version 7 and write my own scaling routines to look at the data ranges and calculate nice starting, ending and increment values for my data?
