... so diesmal gibt es erst Code 😉
Das ganze ist eine Zeichenfunktion für ein Säulendiagramm. Soweit so gut. Jetzt will ich aber auf die einzellnen Säulen auch noch nen Text schreiben ... gehe ich jetzt aber hin und rufe RotateTransform auf, schreibe den Text, rufe wieder RotateTransform auf, erscheint der TExt nicht, aber die Säulen haben auf einmal nen komischen abstand von einandern ?! Jemand ne Idee warum? Oder wie zeichnen ihr einen gedrehten String? 😃

Doch den Säulen-Hintergrund, oder?
Zeig mal den Code, wo Du den Text zeichnest.

ohne Rotation ... klappt.

mit Rotation:

bool Bar::draw(Gdiplus::Graphics* graphics)
{
	if (graphics == NULL)
		return false;

	Gdiplus::SolidBrush brush_bar(Gdiplus::Color(173, 222, 107));
	Gdiplus::SolidBrush brush_caption(Gdiplus::Color(0, 0, 0));

	Gdiplus::StringFormat	stringFormat;
	stringFormat.SetAlignment(Gdiplus::StringAlignmentNear);
			stringFormat.SetLineAlignment(Gdiplus::StringAlignmentCenter);

	LONG bar_width = min(static_cast<LONG>((m_rect.right - m_rect.left - m_items.size() * 2) / m_items.size()), 20);
	for (std::size_t bar = 0; bar < m_items.size(); ++bar)
	{
		LONG height = ((m_rect.bottom - m_rect.top) / 100) * m_items[bar].first;
		Gdiplus::RectF rect(static_cast<Gdiplus::REAL>(m_rect.left + static_cast<LONG>(bar) * (bar_width + 2)), static_cast<Gdiplus::REAL>(m_rect.bottom - height), static_cast<Gdiplus::REAL>(bar_width + 2), static_cast<Gdiplus::REAL>(height));
		graphics->FillRectangle(&brush_bar, rect);
		graphics->RotateTransform(90.0f, Gdiplus::MatrixOrderAppend);
				graphics->DrawString(m_items[bar].second.c_str(), -1, &m_fontControl, rect, &stringFormat, &brush_caption);
		graphics->RotateTransform(90.0f, Gdiplus::MatrixOrderPrepend);
	}
	return true;
}

klappt nicht ... muss ich erst TranslateTransform aufrufen?
