Hello shikha,

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.Bar bar = new Steema.TeeChart.Styles.Bar(tChart1.Chart);
            bar.FillSampleValues(30);
            bar.Marks.Visible = false;
            for (int i = 0; i < bar.Count; i++)
            {
                bar.Labels.Add("point index " + i.ToString());   
            }

            tChart1.Axes.Bottom.Labels.Angle = 90;
            tChart1.Axes.Bottom.Labels.Items.Clear();

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

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

I hope that will helps,

Thanks,

hey but u are only setting it to 90 degrees which i have already done. but still i m getting error. please let me know if i have missed something i ur code. i can not use your code directly as i have other processing in my code. so if u can tell me what eactly will make a adifference , it will be great. thanks in advance.

Hi shikha,

Do all the points you've added have labels? Note that if you've added some of your points with labels and others without, the axis will be set to show the labels but most of them are empty. For example:

Code: Select all

Steema.TeeChart.Styles.Bar bar = new Steema.TeeChart.Styles.Bar(tChart1.Chart);
bar.Marks.Visible = false;

bar.Add(10);
bar.Add(20, "point index 1");
bar.Add(50);
bar.Add(30);
bar.Add(10, "point index 4");

tChart1.Axes.Bottom.Labels.Angle = 90;

If that's not your situation, please, try to reproduce your problem in a simple example project we can run as-is to reproduce it here.
You can either post your files at news://www.steema.net/steema.public.attachments newsgroup or at our upload page.

Hi
no its not the case . i am adding all points. i can say that because
when i set tcStraAssessRC.Page.MaxPointsPerPage = 4 , I can see all labels and the bars are also clearly shown.

But when i set tcStraAssessRC.Page.MaxPointsPerPage = 10 then i can not see some labels and bars are also diminished in size( in width).

Hi shikha,

I suspect that your chart may be too short to show as many labels in its bottom axis but it would be easier to see what's happening if you could send us a simple example project we can run as-is to reproduce the problem here.

Hi
Plesae let me know is there any way to have a scrollbar in legend. The isssue is my legend contains 40 values and only 10 are showing up.Thanks

[Yeray]

Hi shikha,

In that case, you may be interested on Legend Scroll Bar Tool. Please, take a look at the example
All Features\Welcome !\Miscellaneous\Legend\Legend ScrollBar Tool from TeeChart Feature Demo. You'll find tutorials and demos at TeeChart's program group.

[Neelam]

Hey
Thanks so much, this really looks good..

[Neelam]

Also
I have foound my other issue , I can explain it better now. Actually my labels are VERY long( that is they have around 20-40 characters). So when i set them to
tcStraAssessRC.Axes.Bottom.Labels.Angle = 90

this solves my preoblem of seeing all labels BUT as they are very long they make chart very small ( so the axis is changed and bars become very small respectively as now the labels take most of teh space).

This can be seen in your FEATURE DEMO-ALL features-Basic features-
tChart1.Series.Clear();

tChart1.Series.Add(new Steema.TeeChart.Styles.Bar());
tChart1.Series[0].Clear();
tChart1.Series[0].Add(123, "ABC", Color.Red);
tChart1.Series[0].Add( 456, "DEF", Color.Blue );
tChart1.Series[0].Add( 321, "GHI", Color.Green );

Change the bar Marks :

tChart1.Series[0].Marks.Style = smsValue ;
If i set Axes.Bottom.Labels.Angle = 90, then you can see the chart goes little up and the bars become little small and the axes also changes from 500 to 600.

So as my labels are very big and I want to display them, the chart becomes too small. IS there a solution for this? Thanks in advance.

[Neelam]

Also do we have anything like CHART scrollbar, so that in limited space, we can have this to show everything- chart, lengthy labels without comprimising with the visisbility of chart/bars. thanks.

Hello shikha,

I recomend that see this theardspecifically from page 3 until the last. Where you have explained advanced code for solve the size of words. Also there are all cases of possible if you works with labels axes.


I hope that helps you.


Thanks,

[Neelam]

hI
tHANKS FOR The REPLY. But going through it , i found that the only solution is to use Vertical orientation of labels. But what if I dont want Vertical orienation and still want to show all labels?

[Neelam]

Hi
Its a bit urgent, awaiting ur reply

[Neelam]

sorry for not being clear, what i meant was that showing labels vertically will reduce chart size. how to counter that side effect? Thanks

[Yeray]

Hi shikha,

Maybe a good tip for you could be reducing text size:

Code: Select all

tChart1.Axes.Bottom.Labels.Font.Size = 6;

Also, another possibility could be adding a line break into your label strings:

Code: Select all

        private void InitializeChart()
        {
            chartController1.Chart = tChart1;
            
            tChart1.Series.Add(new Steema.TeeChart.Styles.Bar());
            tChart1.Series[0].Add(123, "really long long label 1", Color.Red);
            tChart1.Series[0].Add(456, "really long long label 2", Color.Blue);
            tChart1.Series[0].Add(321, "really long long label 3", Color.Green);

            tChart1.Axes.Bottom.Labels.Angle = 90;

            tChart1.GetAxisLabel += new Steema.TeeChart.GetAxisLabelEventHandler(tChart1_GetAxisLabel);
        }

        void tChart1_GetAxisLabel(object sender, Steema.TeeChart.GetAxisLabelEventArgs e)
        {
            if (e.LabelText.Length > 16)
            {
                string tmp1 = e.LabelText.Substring(0, 16);
                string tmp2 = e.LabelText.Substring(16, e.LabelText.Length-16);
                
                e.LabelText = string.Format("{0}{1}{2}", tmp1, "\n", tmp2); 
            }
        }
