The Data method is equivalent with Import method. The DataOptions property specifies the options of the Import method. The Data property of the Serie object, defines the list of column-names or column-indexes separated by comma within the control's data, such as "AAPL (open),AAPL (high),AAPL (low),AAPL (close)" or "1,2,3,4".

The Import method loads CSV files / CSV content or data from a safe-array as explained:

• A String expression that indicates the path to a file to be loaded or the content itself. If the expression points to a file, the file's content is loaded.The Import method loads CSV files or CSV content. A comma-separated values (CSV) file stores tabular data (numbers and text) in plain-text form. Plain text means that the file is a sequence of characters, with no data that has to be interpreted instead, as binary numbers. A CSV file consists of any number of records, separated by line breaks of some kind; each record consists of fields, separated by some other character or string, most commonly a literal comma or tab. Usually, all records have an identical sequence of fields. The Source parameter indicates the path to the CSV file to be loaded, or the content itself. For instance, the Import "C:\Program Files\Exontrol\ExGraph\Sample\data.txt"  imports the data.txt file.
• A Safe array of one-dimensional or two-dimension type, which indicates the data to be loaded. The safe array must be with 1 or 2 dimensions, else an error occurs. If the Source parameter refers a one-dimensional array, the content of the array indicates the values of the rows. If the Source parameter refers a two-dimensional array, the first dimension indicates the columns, while the second indicates the rows (unless the Options parameter indicates the "reverse" word, which reverses the columns with rows . For instance, in VB6 you can load data from a safe array using the syntax Import Array(1, 1, 2, 2, 3, 3, 4, 4). Where Array is a method of VB6 that creates a safe array of different values. The same way you can have the declaration Dim data(1,99) as String, and call the Import data, will load a two-dimensional array. The sample loads 2 columns, and 100 rows from the data array.

Here's a few samples of using Import method with arrays, using the /COM version:

• VB,VBA: .Import (Array(1, 2, 3, 4, 5))
• VB/NET: .GetOcx().Import(New Integer() {1, 2, 3, 4, 5})
• C#: .Import(new int[] { 1, 2, 3, 4, 5 }, null);

Here's a few samples of using Import method with arrays, using the /NET version:

• VB/NET: .Import(New Integer() {1, 2, 3, 4, 5})
• C#: .Import(new int[] { 1, 2, 3, 4, 5 });;

The control can load data using one of the following methods:

• Data, equivalend of Import method
• Import method, loads data from a CSV file or from specified text.
• DataSource property, assigns an ADO/DAO record set to be loaded.

The DataSample property gives a sample of the data being loaded.
