I need to create a time series graph for a few random cells with known underlying attribute such as "forest" or "agriculture" based on the VCI (Vegetation Condition Index). I have been reading and looking into time series in QGIS but have not found anything that can do what I need it to do, as most only draw a time series movie of the area and usually only work with vector data, which I need neither of those 2 types of applications.
The time series is 16 years worth of data, based on 16 day NDVI composites which gives a total of about 368 Rasters. I then need to choose some random cells within areas that have known vegetation landuse classes such as a forest. Each cell selection should then have 368 total values (for each Raster). From these 368 values I would like to extrapolate them into a time series line graph format. Something similar to the below image:
So in theory I should be able to make several graphs that would have 368 values on the X-axis representative of the changes through time of the VCI of those specific cells.
Ideally it would be good if the application can either draw this graph and save the values to a .txt or .csv file but also even if it can only save the values to a .csv I can then plot this time series easily in Excel.
