## have a look at diaGrabber/examples/ressources/timeFolders ## here you will find hundreds of folders. in every folder is a file called ## "line5_T.xy". it include values of a distance and a temperature ## the folders itself represents different time-values ######################################################## ## at first we import everything we need from diaGrabber from diaGrabber import source, target, plot from diaGrabber.source.methods import merge, calc, exclude, transform ## we create a instance of a plainText-source f= source.plainText( folder="ressources/timeFolders", file="line5_T.xy", dimSeperator=" ", dataType="float", ## we don't want to see the statusbar for every file, so we set: silentReadout=True ## if you want to have a message for every new file readout, set ## silentReadout to False ) ## if we dont want to do further work on the dimensions itself we dont have to ## write x = source.xDimension - just calling the method is enough f.basisDimension(name="distance",unit="m", index=0, resolution=300) f.mergeDimension(name="Temperature",unit="K",index=1) ## here comes the new part: the folders in the main 'timeFolder' will ## represent a basisDimension. trough defining index='folder' ## if you have a nested system of folders you can add further basisDimensions ## like the following. in this case the order of reference builds the folder-system f.basisDimension(name="time",unit="s",index="folder", resolution=300)
