動作確認

C++ Builder XE4

左軸を対数スケールにする時、LeftAxis->Incrementは0をセットしないと間隔表記がおかしくなってしまうようだ。

	formPtr->Chart_short->LeftAxis->Logarithmic = true;
	formPtr->Chart_short->LeftAxis->SetMinMax(0.00001, 1.0);
	formPtr->Chart_short->LeftAxis->Increment = 0;
	formPtr->Chart_short->LeftAxis->MinorTickCount = 8;

The real cause of the problem is not having this property set:

Points1.Chart.Axes.Bottom.Increment = 0
Points1.Chart.Axes.Left.Increment = 0
Points1.Chart.Axes.Right.Increment = 0
Points1.Chart.Axes.Top.Increment = 0
