I could use the Feature Demo for TeeChart for .NET to reproduce these problems. I specifically used Welcome !\Components\ChartController example

Found the following issues when making changes to the controls on the Page and Format tabs of the print preview dialog

1. When moving the Zoom Slider Bar the chart is repainted when passing each increment. This is very unfriendly. If I want to move the slider from extreme left to all the way to the right, I have to stop and wait for a repaint at each tick mark. Sometimes a repaint takes 15 seconds or longer. The repaint should occur on a mouse up event or something similar, not on the slider change event.

2. When changing the Margin Values using using the UP/Down buttons the chart is repainted This is very unfriendly. It would be better if there was a timer that waited for a pause in my clicking and then repaints the chart.

3. When moving the Detail Resolution Slider Bar the chart is repainted when passing each increment. This is very unfriendly. If I want to move the slider from extreme left to all the way to the right, I have to stop and wait for a repaint at each tick mark. Sometimes a repaint takes 15 seconds or longer. The repaint should occur on a mouse up event or something similar, not on the slider change event.

4. When I changed the Margin Units from 1/100 inch to Percent. The preview flips upside down. Not good

7. Annotations are not positioned correctly in the print preview. Using the Welcome !\Components\ChartController example, I added an annotation and positioned the annotation in the center of the Green triangle. I hit print preview and look at where the label ends up. It is way off position.
