AV on mouse move on empty chart

[Alexandre]

Hello,

There is a AV (access violation) when I follow this steps:

1 - Create new VCL forms application on Delphi XE7 update 1;
2 - Put the TChart component;
3 - Set the property "Legend.LegendStyle" to "lsValues";
4 - Compile and run the application;
5 - Move the mouse over the chart. Occurs here the AV error;
6 - Now, set the property "Hover.Visible" to "false";
7 - Compile and run the application;
8 - Move the mouse over the chart. No problem now;

THE AV ERROR OCCURS ONLY IF THE CHART IS EMPTY.

Anybody know this issue? There is some solution?

Sorry for my English. I am from Brazil.

Thank you,

Alexandre.

Caro Alexandre,

Are you using the latest TeeChart Pro v2015.14?
You can check it adding the TeeConst unit to the uses clause and showing the TeeMsg_Version constant somewhere.
I drop TChart into an empty form on a new VCL application in Delphi XE7, I add the following code and I can move the mouse around with no error here.
May I be missing anything else to reproduce the problem?

Code: Select all

uses TeeConst;

procedure TForm1.FormCreate(Sender: TObject);
begin
  Chart1.Legend.LegendStyle:=lsValues;
  Chart1.Hover.Visible:=True;
  Caption:=TeeMsg_Version;
end;

Hi Yeray,

I was using the TeeChart Pro 2014. I updated to latest version (2015) and this problem is solved.

Thank you,
