How do I scale the Left Y Axis to show a negative Time value.
Values are in the range of less the 1 minute

Hi madup,

Could you please extend on what are you trying to obtain? Could you post an image of it? You can post your files at [url]news://www.steema.net/steema.public.attachments[/url] newsgroup.

What I have is a chart that shows deltas between 2 datasets. Some of the values will be negative. Since the axis is formatted as 'Time', when the values are negative, the scale on the graph is blank

Hi,

the only way I can think of is to set the labels (the ones you want to show) by using the the OnGetAxisLabel event, using similar code to the following :

Code: Select all

procedure TForm1.Chart1GetAxisLabel(Sender: TChartAxis;
  Series: TChartSeries; ValueIndex: Integer; var LabelText: String);
begin
if sender=chart1.Axes.Left then
  if labeltext = '' then
    labeltext := 'mylabel';
end;
