SetIndexLabel does not update

[Wessel]

Using the following code:

Code: Select all

procedure OnParamsChange; stdcall;
begin
  SetIndexLabel(0, 'EMA'+IntToStr(period) );
end;         

Has no effect on the IndexLabel text even when the period is changed to another value with the options menu.

Same using the SetIndexLabel inside the Calculate also seems not to have the ability to change the text.

It looks like if it is set once it is unchangeable after that.

Is this a bug or a misinterpretation of me how to use the function.

How can I change the IndexLabel's when the Parameters are changed ?

Could anybody of the developers of FT please give a proper solution for this or just confirm that it is right now, and fix this Bug? Its a pity as having lines and be able to rename them dynamically opens up a wealth of possibilities.

Hello Wessel,

You are correct, Index Label can be changed only in Init procedure. It is not a bug actually but we'll allow changing Index Label in OnParamsChange in next versions.

Excellent!

Thank you very much for taking that in your next release
