Bar series - Side All

[UserLS]

I have a graph with multiple bar series and labels on the bottom axis. When I set Bar's stack option to "Side All" I have labels only below the first series, the rest of them have no labels at all.

Hi UserLS,

This has been fixed for the next v3 and v4 maintenance releases (TF02014567).

Yes, the labels are fixed (only if we are using labels, but if my bottom axis is showing dates - it is completely broken!). But now if I make my series marks visible and set marks.Style = Label... the first series generates marks for all points on the bottom axis with zeroes for the points, that belong to other series , the second series skips the first, but sure enough has its own "zero" marks over the following series and so on...
You will also have a very interesting results if you will change the first bar series AutoDepth = false and the depth set to something like 20. Especially, if any of the following series have a zero value for one of the points.

Hi UserLS,

Yes, I could reproduce it with the following code so I've added it to the bug list to be fixed in next releases (TF02014600). Are you sure it was fine in a previous v3 maintenance release?

Code: Select all

            new Steema.TeeChart.Styles.Bar(tChart1.Chart);
            new Steema.TeeChart.Styles.Bar(tChart1.Chart);
            new Steema.TeeChart.Styles.Bar(tChart1.Chart);
            Random rnd = new Random();
            DateTime date = new DateTime(2009, 12, 18);

            for (int ValueIndex = 0; ValueIndex < 3; ValueIndex++) 
            {                
                date = date.AddDays(1);
                for (int SeriesIndex = 0; SeriesIndex < tChart1.Series.Count; SeriesIndex++)                
                    tChart1[SeriesIndex].Add(date, rnd.Next(100));                
            }

            (tChart1[0] as Steema.TeeChart.Styles.Bar).MultiBar = Steema.TeeChart.Styles.MultiBars.SideAll;

. But now if I make my series marks visible and set marks.Style = Label... the first series generates marks for all points on the bottom axis with zeroes for the points, that belong to other series , the second series skips the first, but sure enough has its own "zero" marks over the following series and so on...
You will also have a very interesting results if you will change the first bar series AutoDepth = false and the depth set to something like 20. Especially, if any of the following series have a zero value for one of the points.

If I understand well, the main problem would be the same that results in "zero" extra marks and the "depth issue". It seems that having SideAll, the first series is drawing bars with value 0 where the other bar series are going to be drawn. This produces these marks (having first series marks visible) and the depth issue. Here is a code to reproduce the problem.

Code: Select all

            new Steema.TeeChart.Styles.Bar(tChart1.Chart);
            new Steema.TeeChart.Styles.Bar(tChart1.Chart);
            new Steema.TeeChart.Styles.Bar(tChart1.Chart);

            tChart1[0].Add(100);
            tChart1[0].Add(10);            

            tChart1[1].Add(8);
            tChart1[1].Add(0);

            tChart1[2].Add(8);
            tChart1[2].Add(0);

            (tChart1[0] as Steema.TeeChart.Styles.Bar).MultiBar = Steema.TeeChart.Styles.MultiBars.SideAll;
            tChart1[0].Marks.Arrow.Color = Color.Green;
            (tChart1[0] as Steema.TeeChart.Styles.Bar).Depth = 20;
            tChart1[1].Marks.Visible = false;
            tChart1[2].Marks.Visible = false;   

I've added this too to the bug list to be fixed asap (TF02014601).

Hi UserLS,

Studying TF02014600, we've realised that this is not a bug but a limitation in design. The SideAll style forces you to have the default X values (0, 1, 2,...) so the datetimes can't be used. Instead of adding your bars with X value like, for example:

Code: Select all

tChart1[SeriesIndex].Add(date, rnd.Next(100)); //public int Add(DateTime x, double y)

You could add the values with the date as label and show it:

Code: Select all

tChart1[SeriesIndex].Add(rnd.Next(100), date.ToShortDateString()); //public int Add(double value, string text)
