I have a CSV file with water level measurments in a well, taken once a year for 40 years. Is there a way to show this data as a graph (x axis being the date and y axis the water level) in QGIS?

Why do you need to produce the graph using QGIS? I would suggest using R (free software) or excel.

in R:

go to file / change dir... and navigate to the folder with your csv

code:

data = read.csv("yourdata.csv")
x <- data$date
y <- data$waterlevel
plot(x,y)
?plot

If you need to display the graph in QGIS you can save the image as a TIFF from R and import it into QGIS.

  • I have hunderds of wells but need only the one closest to the site I'm working on. So selecting the closest wells in QGIS is very simple. I can copy the data of those specific wells to Excell, but thought maybe there's a plugin in QGIS that creates such a graph. – H.Wiener Nov 19 '14 at 8:54
  • Check out the TimeSeriesPlot plugin in the QGIS User-Contributed Python Plugin Repository, it might serve your purposes. – cartoscience Nov 19 '14 at 21:31
