Labeling on Left Axis with HorizBar

[Centrii]

Hi

I use the TChart for .Net v3 latest Version.
Now I have in my ASP.Net Application a problem with the labels on the Left Axis with a HorizBar.
If I have less than 20 DataPoint, every Point has its on label, but if I have more than 20, only every 5th Datapoint has a Label.

Can you tell me how I can solve this issue?

Thank you in advance

Hi Ruben,

Probably your left axis is too short to show 20 labels without overlapping. That's why the chart only draws some of them. If you want you can use custom labels to force the labels you wish to be drawn.

Hi Yeray,

Thank you for your quick answer.
The Left Axis isn´t to short, there is enough Space left between the labels, so there would be not a overlapping.

I think thats a problem with Major Ticks, or something like that. But I didn´t find a way to solve the problem so far.

Mayby you have an other Idea.

thanks

Hellon Ruben,


Please check that next code, when you make chart biggest, all labels appears and when you make chart smaller some labels disappears, because doesn't fit in the Left Axes and labels doesn't overlap.

Example:

Code: Select all

 private void InitializeChart()
        {
            tChart1.Dock = DockStyle.Fill;
            Steema.TeeChart.Styles.HorizBar hbar = new Steema.TeeChart.Styles.HorizBar(tChart1.Chart);
            hbar.FillSampleValues(30);
        }

Thanks,

Hi Centrii,

Thanks for your Help, but I dont have the Dock Property in my Chart.

Using latest TeeChart for .NET v3 release available as you say you should have Dock property. Could you please check it again?

Yes, you can post your files at news://www.steema.net/steema.public.attachments newsgroup or at our upload page.

Thanks in advance.

Hi Narcís,

I´m using TeeChart Version=3.5.3371.26406, and I definitely don´t have the Property Dock, neigther at the Chart nor at the Webchart and I´m using the TeeChart as TempChart="Httphandler".

I did an upload on the Upload-Page, there you can see my Problem.

Thanks,

Hello Centrii,

I make a simple example using custom labels, please check that next code works fine in your application.

InitializeChart():

Code: Select all

private void InitializeChart()
        {
            Steema.TeeChart.Styles.HorizBar bar = new Steema.TeeChart.Styles.HorizBar(tChart1.Chart);
            bar.FillSampleValues(75);
            bar.ColorEach = true;
            bar.Marks.Visible = false;
            for (int i = 0; i < bar.Count; i++)
            {
                bar.Labels.Add("point index " + i.ToString());   
            }
            tChart1.Axes.Bottom.Labels.Items.Clear();

            for (int i = 0; i < bar.Count; i++)
            {
                tChart1.Axes.Left.Labels.Items.Add(bar.YValues[i], bar.Labels[i]);
            }
        }

If you want a more advanced code for solve the possibles problems of overlap you could see this theard specifically the last pages, that there are specific examples and the all possibilities if you can use to fix your issue.


Only, that you change Tchart1 for webChart1, because you can use the code with webChart.

I hope that will helps,

Thanks,
