export data with datetime axis

Post by bahmed » Tue Dec 16, 2003 9:26 pm

Hi,

I am trying to export data from an activeX teeChart using "Editor dialog".
The x-axis is in "datetime" format but the exported data shows "floating point" vlaues for X-axis (as shown below).

----- code for pupulating the series -----
MyChart.Axis.Bottom.Labels.DateTimeFormat="MM/dd/yy hh:mm:ss";
MyChart.Axis.Bottom.AutomaticMaximum=false;
MyChart.Axis.Bottom.Maximum = dblStopTime;
MyChart.Axis.Bottom.AutomaticMinimum=false;
MyChart.Axis.Bottom.Minimum = dblStartTime;

/* rs is a recordset with two field v1 and v2 in it */
MyChart.Series(0).DataSource=rs;
MyChart.Series(0).XValues.ValueSource="v1";
MyChart.Series(0).YValues.ValueSource="v2";

// if I add following lines then I can get the datetime to
// show up in the export, but "floating point value" of the
// time still shows up in the exported .txt data
//
//MyChart.Series(0).LabelsSource = "v1";
//MyChart.Axis.Bottom.Labels.Style= TeeChart.EAxisLabelStyle.talValue;


------------- output of the data export-------

Have you set the XValues of the Series to DateTime ?

MyChart.Series(0).XValues.DateTime = True

Yes I set the DateTime property to true (which was not shown in the code segment). The problem is not in the display of the chart (or graph) but in exporting the data to a txt file using TeeChart Editor dialog's Export-> Data -> (Format: txt) & (Include: Point Index, Point Label)...

I want to export the time in "actual date time" not in floating point value


Look at the exported text data: the second column is souposed to be date-time.

Which TeeChart version are you using ?
It works fine here using the latest TeeChart Pro v6.04. I've attached one example to the steema.public.attachments newsgroup, could you please test it if works fine for you ?

Yes, you're correct, I'm able to reproduce the problem here using the TeeChart Pro v5.05. This problem has been solved in the TeeChart Pro v6.0.
