Description narcís calvet 2014-01-09 04:37:21 EST 
According to the description of AddArray function, the second parameter means the data number of the first parameter? But actually it is the data number - 1 ? So if I have a array of 10 elements, I should add data like below?

   double array[10] = {1, 2,3,4,5,6,7,8,9,10};
   Series1->AddArray(array, 9);

Solution:

Series1->AddArray(EXISTINGARRAY(array));

Explanation:

This is a confusing problem with Delphi compiler generating the *.hpp header file.
The second parameter is misleading, named "size" but in reality it is passed the High(array) value ( Count - 1 )

We cannot control the param name, it is generated automatically by Delphi compiler.

Just adding the link to the latest version of the docwiki explanation, since the previous link doesn't work any more.
