	From the log menu, the "Export CSV" entry allows to export synchronised values to raw text format (which then can be imported in any spreadsheet, scilab, ...). It opens a popup window where values from the messages to export are chosen. Timestamped lines of values (separarated with semicolons) are produced on a periodic basis (e.g. 0.25s) or synchronously with a chosen message (e.g. GPS). Exported values ~~are~~ at time t are the values from the more recent messages. The configuration (clicked values) is saved (in conf/%gconf.xml) and loaded as default.

	The curve can be scaled by a factor by entering a value in the "Scale next by" entry. For example, to compare the desired and the measured pitch attitude, select "theta" from the "ATTITUDE" message with a (default) scale of 1., then set 57.3 (to convert radians into degrees) in the scale box and select "pitch" field from the "DESIRED" message.		The curve can be scaled by a factor and an offset (separated with a "+") can be added by entering a value in the "Scale next by" entry. For example the value "1.8+32" translates degrees Celcius into degrees Fahrenheit. For example, to compare the desired and the measured pitch attitude, select "theta" from the "ATTITUDE" message with a (default) scale of 1., then set 57.3 (to convert radians into degrees) in the scale box and select "pitch" field from the "DESIRED" message.

	To zoom on the curve, unselect the "Auto Scale" checkbox and choose the appropriate time/Y min and max.		To zoom on the curve, unselect the "Auto Scale" checkbox and choose the appropriate time/Y min and max.
