Hello,

I'd like to have all marks vertical (content readable from the right side) and attached to the upper border of the chart.

I've done the following:

• Series->Marks->Angle = 90
• In Series->AfterDrawValues

  Code: Select all

  int num_pos = Series->Marks->Positions->Count;
   for (int i = 0; i < num_pos; ++i)
    Series->Marks->Positions->Position[i]->LeftTop.y = 0;
  

Result: Marks are rotated but not aligned to upper chart border. How can I move the marks there?

Hi to2,

You also have to change the Custom property: If you still have troubles with it, don't hesitate to let us know.

You also have to change the Custom property:

I did so. 3 new problems occur:

1. It seems as if the y=0 position is set when the mark is not rotated, after that the 90° rotation is performed around a center which is the center of the mark. Result: the marks don't have their LeftTop at y=0 but their "LeftCenter". The vertical center of the mark is at y=0 and the LeftTop is outside of the chart area.
2. ArrowLength doesn't follow to the new position of mark.
3. If I scroll the BottomAxis then marks and arrows don't follow to the new position of the series.

I wonder if I could get the desired behaviour by keeping Custom = false and modifying the ArrowLength of each mark instead. Is there an event fired, before a mark is drawn, so that I can calculate the mark dimensions and set the ArrowLength accordingly?

What are

• TSeriesMarkPosition::MidPoint and
• TSeriesMarkPosition::HasMid

for? I can't find information about these properties in my online help.

Got it working. Have to set many things (ArrowFrom, ArrowTo, LeftTop ...) manually. Have to consider that mark's width and height are measured before rotation. But finally it does what I want.

Hi to2,

I'm glad to see you found it. If you still have any problem, regarding this or not, don't hesitate to let us know.
