Hi All,

Recently we upgraded TeeChart from 2015 to 2020 version. We noticed following difference when showing marks on bar:
Before:

After:

New 'Tails' feature is configurable and can be switched-off. One more difference is lowered marks inside the bar.
Is it possible to get them to original position?

We use 'end' location of marks.

The workaround I found is:
- switch-off 'Marks on bar' property;
- set Marks->Arrow->Distance property to '-28'.
Doing so I got marks on similar position, but I wonder whether there is a 'legal' way to achieve it.

Thank you,
Taras

Hello!

How about:

Code: Select all

        Bar _bar = new Bar();
        
        private void InitializeChart()
        {
            _tChart.Series.Add(_bar);
            _bar.FillSampleValues();

            _bar.Marks.TailStyle = MarksTail.None;
            _bar.MarksOnBar = true;
        }

which gives me:

Hi Christopher,

Thanks for your reply.

Indeed, found that property to remove tails. Screenshots were made earlier.

Is it possible to also place marks a bit higher within the bar?

At this sample it's not a big deal, but in our case marks have multiple lines and get cut when bar is almost 0 height.

Regards,
Taras

Hello,

if you're not entirely happy with the position at which 'MarksOnBar' leaves the SeriesMarks, you can turn it off and modify their position using ArrowLength, e.g.

Code: Select all

        Bar _bar = new Bar();
        
        private void InitializeChart()
        {
            _tChart.Series.Add(_bar);

            _bar.FillSampleValues();

            _bar.Marks.ArrowLength = -10;

            _bar.Marks.TailStyle = MarksTail.None;
            //_bar.MarksOnBar = true;
        }

Ah, sorry, I must have misread your first message and missed your reference to Marks.ArrowLength! Either way, although the negative numbers may look a little strange, this is the most 'legal' way I can find to modify the position of SeriesMarks when Marks.AutoPosition is true.
