Please note that the example above is not meant to be executed (makes no sense to execute
the commands in that order in one script).
The value history of a 2D Graph object is stored in binary ring buffers on the non-volatile
memory of the device. In order to process the data on a PC (e.g. spreadsheet application), it
needs to be copied to an external media (e.g. usb drive).
As soon as this function is called, the copy process will start. The progress can be observed
in the Copy Progress Variable of a 2D Graph. While copying is in progress all new values
of the 2D Graph will be buffered and will not get lost. After the copy has finished (Copy
progress variable value is 100), the external media can be removed and the data can be
processed with the Graph History Tool on a PC.
Prototype:
var result = save2DGraphHistory(number Graph-DDO-ID, string targetPath);
The result of this function is true if the copy process could be started (correct object ID and
target path was provided). This does not mean that the copy process has successfully
finished.
Example (copy to USB drive):
//Get path of mounted USB drive:
var usbMountPath = getVariableValue("@USBMountPath");
