Export of data #43

Open mpopara opened 4 years ago

mpopara commented 4 years ago

When exporting the data, writing frequency is not uniform: often it happens that initially writes data with dt step, and then few points with 2*dt step, and then goes back to dt writing frequency, and so on. This happens randomly in the data array, and is difficulty for post-processing of the saved data- such as combining VV and VH models into anisotropy etc.

Only it happens when one uses: right click on plot->export data. With option: File-> Save Fit result, this problem does not occur. However, with "export" approach you will save the fit curve in the actual fit range, while "save fit" gives you full range fit, even though you fitted in smaller range.

I am not certain how to reproduce the behavior you report.

This sounds like an issue may be the used plotting library. If you export / save data via the plot window by right clicking on the plot and "save" the data that are displayed, the plot window is saved as is. The data in the plot may be may be downsampled for performance reasons. You can check if you accidentilly downsample the data in your plot (right click on Plot -> Plot Options -> Downsample).
