PolygonAnnotation, graphique et pixel

Version imprimable

Bonjour à tous,

Je souhaite réaliser un polygon annotation sur un graphique (droite définie par des coordonnées X et Y de mon abscisse et de mon ordonnée)

Il semblerait que le polygon annotation soit défini en pixel par rapport au chart area et non en points X et Y par rapports à mes abscisses.

Je voulais savoir s'il était possible de transformer des coordonnées X et Y de mon abscisse et de mon ordonnée en coordonnées pixel ?

Mon graphique :

Bonjour,

je te conseil de regarder ce tuto pour mieux comprendre les chartGraphiques
http://plasserre.developpez.com/cours/chart

pour répondre a ta question, auncune idée :mrgreen:
ou as tu trouvé ce code?

pour les annotation, tu a le chapitre qui va bien, et la au moins tu comprend ce que tu fait
III-B-7. Annotations

Merci pour ces infos.

Je me suis déjà appuyé sur ce cours pour réaliser mes graphiques et c'est vrai qu'il est très bien fait. Et même s'il explique la façon de réaliser des annotations il n'explique pas comment faire des polygon annotation et il semblerait que la méthodologie de ce type d'annotation diffère des annotations plus conventionnelles.

Encore merci pour ton aide

Oui je m'en suis rendu compte après :(

bah écoute même en regardant le site msdn pour comprendre le système des anotations Points
J'ai trouvé ceci

AnnotationPathPoint()

Initialise une nouvelle instance de la classe AnnotationPathPoint.
AnnotationPathPoint(Single, Single)

Initialise une nouvelle instance de la classe AnnotationPathPoint avec les valeurs x et y spécifiées.
AnnotationPathPoint(Single, Single, Byte)

Initialise une nouvelle instance de la classe AnnotationPathPoint avec les valeurs de point x, y et type spécifiées.

Sachant que tu ne fais que
Code:

1 2 Dim AnnotationPathPoint1 As System.Windows.Forms.DataVisualization.Charting.AnnotationPathPoint = _ New System.Windows.Forms.DataVisualization.Charting.AnnotationPathPoint()
tu dois donner des valeur à X et Y
X -> Obtient ou définit la coordonnée X du point de tracé d'une annotation.
Y -> Obtient ou définit la coordonnée Y du point de tracé d'une annotation.

après je ne comprend pas ou est ton soucis,
pour moi les points d'exclamation devraient générer une erreur
(jamais vue ça en vb.net)

en te regardant le détail de la class, tu sais quels sont les paramètres accessibles ainsi que ce que tu veux en faire
Bref tout est sur la toile... (sauf ton réel problème ^^)

J'ai trouvé ça aussi pour convertir des points en Pixel (vue que ça dépend de la résolution de ta machine
Code:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 Public Declare Function GetDC Lib "user32" (ByVal hwnd As IntPtr) As Int32 Public Declare Function GetDeviceCaps Lib "gdi32" (ByVal hdc As IntPtr, ByVal nIndex As Int32) As Int32 Public Declare Function ReleaseDC Lib "user32" (ByVal hwnd As Int32, ByVal hdc As Int32) As Int32 Public Const LOGPIXELSX = 88 Private Const POINTS_PER_INCH As Long = 72 Public Function PointsPerPixel() As Double Dim hDC As IntPtr Dim lDotsPerInch As Int32 hDC = GetDC(IntPtr.Zero) lDotsPerInch = GetDeviceCaps(hDC, LOGPIXELSX) PointsPerPixel = POINTS_PER_INCH / lDotsPerInch ReleaseDC(IntPtr.Zero, hDC) Return PointsPerPixel End Function

Merci beaucoup pour ton aide !

Je vais regarder ça de près !

En fait mon problème c'est qu'à priori le polygon annotation nécessite des coordonnées de type X et Y en pixel or je souhaiterais les définir en valeurs abscisse et ordonnées de mon graphique. (Le but étant de définir différentes zones (ou domaines) sur mon graphique).

PS mon graphique est une courbe définie par des axes (graphique de type scientifique).

Encore merci de ton aide, je vais regarder tes suggestions et je reviens te voir si je n'y arrive pas

Bonjour,

Voici mon code mais rien n'est affiché (ormis le graphique et l'annotation (ano2) mais pas mon polygon annotation (annot))

Je ne comprends pas pourquoi.
