Hello,

You can change the number of days in the line 

int NbreGraphes =23;

Thanks

Hi,

Please try the attached fix.

I added "LegendBox.MarkerSize" for getting a custome marker size. In current version, marker size relate to chart area width. When we add graph number, chart area width is decreased and then marker size is decreased too.

Hi,

Yes, our next official release of the component would include the functionality of this fix.

Thank you.

Hi,

Hi,

Well, you may use this fix without any problem, the fix will be like the official version. However, you can expect the next official version (which will include the functionality of the fix) before the end of next week if we complete all the tasks on hand.

Thank you.

Good morning,

Always with the same program, I have a new problem. When I figure in a stream to the page, the graph is correct, but when I save in a file on the site to be able to recover later, the details of the Y axis appear several times.

The code :

//

// Suppression des information à gauche de l'axe des Y sauf pour la première série

// -----------------------------------------------------------------------

for (int intGraph = 1; intGraph < NbreJoursOuvres; intGraph++)

{

c.ChartAreas[intGraph].AxisY.AxisLabels.Clear();

c.ChartAreas[intGraph].AxisY.MajorTickMark.IsVisible = false;

c.ChartAreas[intGraph].AxisY.MinorTickMark.IsVisible = false;

}

//
// Sauvegarde du fichier dans un répertoire temporaire
// ----------------------------------------------------
string StrNomDuFichier = Server.MapPath("./Temp") + "/Graphique_Aspose_Chart_KO.png";
c.Save(StrNomDuFichier);

--> Legends on the Y axis appear several times

//
// Affichage du résultat dans le fond de la page
// ---------------------------------------------
MemoryStream ms = new MemoryStream();
c.Save(ms, ImageFormat.Png);

Response.Clear();
Response.ContentType = "image/png";
Response.OutputStream.Write(ms.ToArray(), 0, (int)ms.Length);

-- > The chart is OK

Thanks for your help

Hi,

Thanks for providing us the template images.

Yes we found the issue, we will figure it out soon.

Thank you.
