Hi,

I am plotting a line series. After that, I am plotting another line series on the same graph. The bottom axis has dates, but the dates are not equally spaced. I want to modify the ticks and the labels on the bottom axis so that they look nice.

I want to equally space them so that the distance between two ticks is 1 year. Please help.

Regards,

Amol

Hi Amol,

You could try setting DateTime axis increment as told in Tutorial 4 - Axis Control. Tutorials can be found at TeeChart's program group.

Hi Narcis,

Thanks for the prompt reply. I want to add data for every month for 50 years. However, I want to display only 50 labels on the bottom axis. One label per year.

How do I do this?

Thanks.

Hi Amol,

Code below does what you request:

Code: Select all

Private Sub Form_Load()
    TeeCommander1.Chart = TChart1
    
    TChart1.Aspect.View3D = False
    
    TChart1.AddSeries scPoint
    TChart1.Series(0).XValues.DateTime = True
    
    TChart1.Axis.Bottom.Labels.Angle = 90
    TChart1.Axis.Bottom.Increment = TChart1.GetDateTimeStep(dtOneMonth)
    
    NumberOfPoints = 12 * 50 '12 months per 50 years.
    Today = Now
    
    For i = 0 To NumberOfPoints
        TChart1.Series(0).AddXY Today + i * 30, Rnd, "", clTeeColor
    Next
End Sub

However, TeeChart automatically draws the labels in the desired increment provided they fit in given axis space. Otherwise draws the minimum increment that makes labels not overlapping. If you use code above and zoom in the series you'll see that a label every month is plotted.

Hey Narcis,

BTW, Congrats on Spain's victory in the EURO CUP!! That's wonderful!

I am having problem when I am trying to display two different series on the same graph. I want to send you a word document that has a screenshot that displays the problem and the code snippet. I made changes as per your suggestion. However, my problem is when I am trying to display more than one series, the continuity in the labels breaks even though the series are one after the other.

Please help!

Hey Narcis,

I was able to upload the file containing the screenshot that describes my problem. I have uploaded this from the web based upload page.

Hi Amol,

BTW, Congrats on Spain's victory in the EURO CUP!! That's wonderful!

Thanks for the sentiment. Hope this will be good for spanish football since my favourite team (F.C. Barcelona) plays in the spanish league:

http://en.wikipedia.org/wiki/FCBarcelona
http://www.fcbarcelona.com/web/english/

However, Steema Software is based in Catalonia:

http://en.wikipedia.org/wiki/Catalonia
http://www.gencat.cat/catalunya/eng/

I was also born in Catalonia in a Catalan family and thus my mother tongue is Catalan so you may understand that I don't feel identified with Spain. I wonder if this is a common feeling in Steema Software

I am having problem when I am trying to display two different series on the same graph. I want to send you a word document that has a screenshot that displays the problem and the code snippet. I made changes as per your suggestion. However, my problem is when I am trying to display more than one series, the continuity in the labels breaks even though the series are one after the other.

This could be that you are using series text labels as bottom axis labels. You could try setting axis labels style like this:

Code: Select all

    TChart1.Axis.Bottom.Labels.Style = talValue

If this doesn't help, could you please send us a simple example project we can run "as-is" to reproduce the problem here?

Thanks in advance.

Dear Narcis,

Sorry about the late response. The solution you provided brought me closer to solving my problem, however, there is a new issue. I am sure you can help me with this. Now, when I use: m_ChartRate.GetAxis().GetBottom().GetLabels().SetStyle(talValue); as per your instructions, TeeChart places the labels at equal intervals. However, my labels are dates, which are being fed to TeeChart as strings as:

m_ChartRate.Series(4).AddXY(t,propVal,datestring,clTeeColor);

Where:
t is the time value in double
propVal is the property value to be displayed on Y axis
datestring is the date in string format corresponding to the t (described above)
and then the color.

I have uploaded the screenshot on: http://www.steema.net/upload/Default.aspx

Can you please guide me on how to display the date strings on the X axis (Bottom axis) in a format: mm/yyyy

Thanks for your kind help.

Best regards,

Amol

Dear Amol,

Yes, in that case you'd need to set series' X values as being DateTime, for example:

Code: Select all

	m_Chart1.Series(0).GetXValues().SetDateTime(true);

Hope this helps!

Hey Narcis,

I think with your kind help, I'll soon get there and resolve my problem. Now, I am getting some dates that range from 1900 to 1916. However, the corresponding dates should ideally range from: 1992 to 2007

I am enclosing the data here. The X values are the ones that I get after doing the conversion using the function that you had provided. The data shown under the header Text is the data that I should get on the X axis. The text data is the one that I am getting after converting the double values to date-time format in my code and then converting it to text for the labels purpose. I am also uploading the screen-shot of the issue. Please help me in resolving this problem.

Best regards,

Amol
