Problem with markers in the pie-type graphic

Hi,

We have a problem when displaying a pie-type graphic with persistent marks, showing information of portions of the pie. The matter is that the marks take as much space as they need to display their information, thus reducing drastically the displaying space for the pie. The result is a perfectly visible mark, but an almost invisible pie.

Is there any way to let the mark to be drawn over the pie, so the display space of the pie is not reduced?

Thanks in advance.

Hi Teltronic,

Yes, you can use custom marks position for that. You'll find an example here.

Hi Narcis,

I think that's not exactly what we need. We don't want to place the mark in other position; we just want to know if it is possible that the mark is painted over the pie. We don't have an available URL for posting the image, so I'll try to make an schema. This is more or less the situation:

_________________________________________

############
############
############

[+++++++++] **** [++++++++++]

[ LEGEND ]

_________________________________________

The # symbols mean to be the graphic header. As you see, the marks (painted with '+') are taking as much space as they need, thus reducing the pie size (painted here with '*'). We'd like to know if it is possible to change this behaviour so that the pie is not displayed in such a small manner.

Thanks in advance.

Hi Teltronic,

The only alternative I can think of is setting negative mark arrow length:

Code: Select all

    TChart1.Series(0).Marks.ArrowLength = -20
    TChart1.Series(0).Marks.Arrow.Visible = False
