Loading Data using TSeriesTextSource 8.04

[timhamel]

I am having problems importing values into my chart using a text source. I am using RAD 2007 C++ mode, TeeChart 8.04.

The actual chart is simple: X axis is TDateTime and Y is Temperature. I am using a text file which should populate the graph. Both axis are set to automatic. When the text file is generated, the TDateTime part is saved as a double from the VAL member of TDateTime. The file looks like this:

40108.749417 95.000000
40108.749429 95.000000
40108.749441 95.000000
40108.749452 95.000000
40108.749464 95.000000

The SeriesTextSource component used for the read in is set up as:

DecimalSeparator ='.';
SeriesTextSource1->Fields->Clear();
SeriesTextSource1->Series = Series1;
SeriesTextSource1->AddField("X",1);
SeriesTextSource1->AddField("Y",2);
SeriesTextSource1->FieldSeparator = " ";
SeriesTextSource1->HeaderLines = 0;
SeriesTextSource1->Series = Series1;
SeriesTextSource1->FileName = sFileName;
SeriesTextSource1->Active = true;

The problem is: the component throws an exception when reading in the date with the following:

Exception class= EConvertError
ExceptAddr= 0048170E
ExceptionMessage= '40108.749417' is not a valid date and time

What value is your component expecting?

Hi Tim,

Please see my reply at the other thread and please, don't open multiple topics with the same question.

Thanks.

Sorry for having 2 cases open. I thought that for users having the same problem and looking for a solution, changing
the topic header would help. Will not create more work for you in the future.

Cheers,
Tim
