Is there a way to display the data item label within the bar rectangle like this? (Please excuse my ASCII art...)

-----------------------------------------------------
Item 1                                              |
-----------------------------------------------------


-----------------------------------------------
Item 2                                        |
-----------------------------------------------


---------------------------------------------------------
Item 3                                                  |
---------------------------------------------------------

Hello t-chizzle,

You can use the MarksOnBar to draw the bar in your end. The code below shows you how:

Code: Select all

        Steema.TeeChart.Styles.HorizBar horizbar;
        private void InitializeChart()
        {
            horizbar = new Steema.TeeChart.Styles.HorizBar(tChart1.Chart);
            horizbar.FillSampleValues(3);
            horizbar.CustomBarWidth = 50;
            horizbar.MarksOnBar = true;
            horizbar.MarksLocation = Steema.TeeChart.Styles.MarksLocation.Start;
        }

Thanks in advance

Thanks Sandra. That seems to sort basically sort it, but in my use case there is an issue that you should be able to see from the attached image.

The min and max are set to 0 and 120, but he graph is resized as if the marks are attached to the edge of the bar. When the label is longer than the screen the data entirely disappears.

Is there a way around this?

Hello t-chizzle,

Marks are split in lines when you choose a "compound" mark style like: MarksStyles.LabelPercent, MarksStyles.LabelPercentTotal or MarksStyles.XY.

You can also make marks having multiple lines adding line breaks into them, for example:

Code: Select all

   private void InitializeChart()
        {
            horizbar = new Steema.TeeChart.Styles.HorizBar(tChart1.Chart);
            Random rnd = new Random();
            horizbar.Add(10, 50,"Name");
            horizbar.Add(20, 70, "Short\n Name");
            horizbar.Add(50, 30, "Very long name that \n causes some problems");
        
            horizbar.CustomBarWidth = 50;
            
            horizbar.MarksOnBar = true;
            horizbar.Marks.Transparent = true;
            horizbar.Marks.MultiLine = true;
            horizbar.MarksLocation = Steema.TeeChart.Styles.MarksLocation.Start;
            tChart1.Axes.Left.Labels.Style = Steema.TeeChart.AxisLabelStyle.Value;
            tChart1.Axes.Left.Inverted = false;

Using GetMarkText event you can automatically parse marks text too. You could replace blank spaces for line brakes or implement any customization you wish.

Thanks in advance,

Hi Sandra,

I don't think the problem is due to not being able to split the labels. The problem is that the size of the bar shrinks as the length of the mark grows. This makes sense when the label is on the end of the bar, but when it's at the beginning it's the wrong thing to do. In the image above, if I don't use a mark the axis is 0 -> 120 and the red value goes all the way to the end.

The extra whitespace at the end is the length of the largest mark. The end of the bar moves left as if it was allowing space for the mark to be drawn on the end.

Thanks

Hello t-Chizzle,

Could you attach the simple project you're using because we can reproduce exactly the problem here?

Thanks in advance for your help,

Hi Sandra,
How do I get the updated dll?
Thanks

Hello t-chizzle,

How do I get the updated dll?

We will prepare for you a Teechart.dll.
Could you tell us in which version you are working(specifying .Net Framework).
Also, could you tell us if you want TeeChart.dll signed or unsigned?

Thanks in advance

Hi Sandra,
I'm using the dll that lives in this directory: Steema TeeChart for .NET 2015 4.1.2015.12160\net45\x86

I guess that means .net 45, x86, signed.

Thanks
