Ok, I'm at a loss as to why my bar series is always black ... I am using the solid brush with Lime as the color and the bars are always black no matter what I seem to do. Please help :x BTW I'm using v7.0.0.4

Here is my .tee file:

Code: Select all

object TChartChart
  Left = 5
  Top = 5
  Width = 807
  Height = 456
  AllowPanning = pmNone
  BackWall.Transparent = False
  Title.Font.Color = clBlack
  Title.Text.Strings = (
    'Advanced Graph')
  BottomAxis.Automatic = False
  BottomAxis.AutomaticMaximum = False
  BottomAxis.AutomaticMinimum = False
  BottomAxis.Grid.Color = clBlack
  BottomAxis.Maximum = 38506.501388888880000000
  BottomAxis.Minimum = 38506.494444444440000000
  BottomAxis.MinorTicks.Color = clBlack
  BottomAxis.Ticks.Color = clBlack
  LeftAxis.Grid.Color = clBlack
  LeftAxis.MinorTicks.Color = clBlack
  LeftAxis.Ticks.Color = clBlack
  Legend.LegendStyle = lsSeries

  RightAxis.Grid.Visible = False
  RightAxis.MinorTicks.Color = clBlack
  RightAxis.Ticks.Color = clBlack
  Zoom.Animated = True
  BevelWidth = 0
  Color = clSilver
  object Series0: TBarSeries
    BarBrush.Color = clLime
    BarPen.Color = clLime
    BarPen.Width = 0
    Marks.Callout.Brush.Color = clLime
    Marks.Visible = False
    SeriesColor = clLime
    Title = 'Bar'
    Gradient.Direction = gdTopBottom
    XValues.DateTime = True
    XValues.Name = 'X'
    XValues.Order = loAscending
    YValues.Name = 'Bar'
    YValues.Order = loNone
    Data = {
      030A000000D8822DD84FCDE240D7A3703D0A77524000000000DEDDDDDD4FCDE2

Hi,

I have been able to reproduce the problem importing your .tee file but haven't been able to reproduce it from scratch. I've already posted a project trying to reproduce it at [url]news://www.steema.net/steema.public.attachments[/url] newsgroup. Exporting the chart will also create a .txt copy of the .tee file. Could you please have a look at it and let me know if you can reproduce the problem on this project?

Thanks in advance.

I found the problem. All you have to do is set the series color property.

Code: Select all

Private Sub Form_Load()
    TeeCommander1.Chart = TChart1
    
    'Set the series color and you will see the problem!
    TChart1.Series(0).Color = clLime
    
    TChart1.Series(0).asBar.BarPen.Width = 0
    TChart1.Series(0).asBar.BarBrush.Color = clLime
    TChart1.Series(0).Marks.Callout.Brush.Color = clLime
    TChart1.Panel.BevelWidth = 0
    TChart1.Series(0).FillSampleValues 5
End Sub

Hi,

Ah, ok, I've noticed the problem. It doesn't work because you are using Visual Basic and clLime is not a Visual Basic color, it's a Delphi color.

What happens is that TeeChart Pro ActiveX is a wrapper from VCL native version and thus, when creating a .tee file, internally uses Delphi enumerations which can't be used in VB, you should use VB enumerations or set your colors using the chart editor.

Ok, so using your example, if I clear the graph, and import the .tee file I attached here to this thread, what property would I change to get the bars to show up in a color other than black? My project isn't even in VB, I was just modifying your project to try to reproduce the problem.

So what I do is save the attached .tee file as c:\barcolor.tee, then clear the graph and import. Then I bring up the properties for the graph and try to get the bar color to change and I can't do it.

Hi,

It works here changing the series color after importing the chart, doing:

Code: Select all

Private Sub Command3_Click()
    TChart1.Import.LoadFromFile ("C:\BarColor.tee")
    TChart1.Series(0).Color = vbRed
End Sub

If your project is not in VB the syntax wouldn't be the same but should work identically.

I still see black even when I do all of the following. The only color that seems to be affected by the following is the pen color. It shows up as red, but the bar remains black

Code: Select all

Private Sub Command3_Click() 
    TChart1.Import.LoadFromFile ("C:\BarColor.tee") 
    TChart1.Series(0).Color = vbRed 
    TChart1.Series(0).asBar.BarPen.Color = vbRed 
    TChart1.Series(0).asBar.BarBrush.Color = vbRed 
End Sub

Hi TMECHAM,

I've already replied to your last attachments newsgroups message with the working example. Could you please have a look at it and let me know if it doesn't work for you?
