Annotation's Font Size Changed does not redraw.

The font size of an annotation's text style is a dependency property and is bindable. When changing the fontsize through changing the object that is bound to the property, the annotation does not recalculate it's draw rectangle even though the sizing is set to automatic. This causes the text to appe...

Re: Annotation Anchor is responsible for too much.

Im requesting that the arrow source point and the anchor become divorced. I'd like to be able to keep my anchor in the top left corner of my annotation. I'd also like to draw my arrow from the center, or from the corner nearest the target point. Would you add such a feature?

Re: Custom MinorTicks

I too desire a better method for adding alternate types of Tickmarks to the chart. We must use the Custom Tickmarks as a workaround, as the major gridline marks do not achieve everything we desire. Is there any chance in the future of adding a seperate collection for Minor Custom Tickmarks, so we do...

Annotation Anchor is responsible for too much.

I have 2 design goals. Given the desired location of the the top left of my Annotation, draw an annotation at that point. Also, draw a line from the center of the annotation to the target point. The location could be specified in ScreenCoordinates or AxisValues. Example: Adding an annotation at Scre...

Show pointLineSeries only on chart, not in legend.

I'm looking to have the pointLineSeries only appear on the chart. Removing the Title.text leaves an empty location next to the line symbol. Is there a way I can add a series to the chart, without having it appear in the legend?

Annotation Arrow sizing.

For annotation arros, is there any way to programmatically set the arrows head and line thickness to be different?

I'd like the line thickness to be 1.0f, and the head to be 4.0f.

If not, do you suggest any workarounds to change how the arrow draws?

Re: Annotation anchor to snap to corner nearest target point

Since the anchor is used for more than just drawing the line, is there a way I could unhook the the line from the anchor?

Or, if you guys end up doing it, maybe add a flag that sets the line to draw from the target point, to the nearest point on the text box?

Annotation anchor to snap to corner nearest target point.

One commonality of the annotations we create is that the background is often transparent. This is a nice feature, but can be an issue when the anchor point is in the center. Since we draw the line from the anchor point to the text, the line passes through our text, and is not good to look at. Our ol...

While a bit archaic, this is the format I'm presented with. Currently, the \t character is not being represented with whitespace, but is instead...
