Is it possible to show a continuous vertical line as part of Data PointMarker in graph? We have managed to show text labels for our peaks using Data Points and point markers. We have used Sprite to display the TextBlock with peak labels. Now we need to show a vertical line starting from the label text up to the tip of peak. For readability we have kept a vertical space between the data point and the peak label. Hence sometimes it becomes difficult to find which peak points to which peak label. However there is no character to represent a long and continuous line. The OR character shows dotted line. Is there any other control we can use inside the sprite to show as a line?
