I added a tooltip based on code I got from the demos to my chart. I am seeing some ghosting when I drag the mouse over a bar (on a bar chart.) It seems that the machine has a bit to do with it. One of our testers is seeing it worse on her machine which is a little older than mine. I am still seeing it, but not as bad with a newer, more powerful machine. I am defining the tooltip's data template in the code behind (for a couple reason I won't get into at the moment):
private DataTemplate GetToolTipDataTemplate()
{
StringReader markup = new StringReader(
string.Format("{0}{1}{2}{3}{4}{5}{6}{7}{8}{9}",
@"<
DataTemplate
xmlns
=
""
http://schemas.microsoft.com/winfx/2006/xaml/presentation"">",
@"<
Grid
>",
@"<
Border
BorderBrush
=
""
Gray""
BorderThickness
=
""
1""
Background
=
""
#FFF7F7F7"">",
@"<
TextBlock
Text
=
""
{Binding Value, StringFormat='",
LabelFormat,
@"'}""
Margin
=
""
4,4,4,4""
FontFamily

FontSize

@"
Foreground
=
""
#FF494949""
VerticalAlignment
=
""
Center""/>",
@"</
Border
>",
@"</
Grid
>",
@"</
DataTemplate
>"));
XmlReader xmlReader = XmlReader.Create(markup);
return XamlReader.Load(xmlReader) as DataTemplate;
}
Here is an image of the tooltip ghosting:
![]()
I will note that the data template above is a bit different from what you see in the image. I took out the vector image to see if its generation was causing the issue. But it is still doing it.
Any ideas?
