c++ builder / TeeChart > Link > Memory Usage keep increasing when auto scrolling chart

動作環境
C++ Builder XE4

TeeChartを使ってグラフ描画するソフトでメモリリークが発生している。その一因としてTeeChartの情報を調べてみた。

TeeChartのバージョンは違うかもしれないが、同様の症状があるかもしれない。

Using your code together with the GetAxisLabel event, there was no memory leak.
However, I'm unable to access the e.Series and e.ValueIndex.

別途、page2の記載

As I explain in previous message your Memory Usage increase because you use AddLabels().

AddLabels()はこちらでは使っていない。

こちらで使っているのはAddXY()のみ。

AddXY()を繰り返す処理に対して、余分な旧データは適宜Delete()している。これによるメモリリークはないと思っているが、TeeChartの不具合があるかは不明。
