<hr><a name="_details"></a><h2>Detailed Description</h2>
<h3>template<class T><br>
class CChartPointsArray< T ></h3>
Manages an array of points which supports fast resizing.
<p>
This class is used internally to store the data for all the points. The data is stored in a C-style array. The internal buffer can grow dynamically depending on the needs.<p>
The class is a template class with the template parameter being the type of the points to be stored. The points have to provide the following methods: <ul>
<li>
double GetXMin() </li>
<li>
double GetX() </li>
<li>
double GetXMax() </li>
<li>
double GetYMin() </li>
<li>
double GetY() </li>
<li>
double GetYMax()</li>
</ul>

Specifies how the points should be ordered in the array.

This specifies if the points should be ordered on their X values, on their Y values or not ordered (kept in order they are added to the control). Ordering can improve performances a lot but makes it impossible to draw some specific curves (for instance, drawing an ellipse is only possible if no ordering is set).

I am a 29 years old guy and I live with my girlfriend in Hoegaarden, little city from Belgium well known for its white beer
.
I studied as an industrial engineer in electronics but I oriented myself more towards software development when I started to work.
Currently I am working in a research centre in mechatronica. I mainly develop in C++ but I also do a bit of Java.
When I have so spare time, I like to read (mainly fantasy) and play electric guitar.
