[Qgis-user] how show themes from single polygon having rainfall time series data

[Brent Wood]

One way that might work for you, see the QGIS action tool.

Create a system invoked R script that plots the time series for a specified polygon, taking the polygon ID as a parameter on the command line.
Then create a QGIS action that invokes the script & passes in the polygon ID.

I have done something similar with Postgis/QGIS & R - the R function was embedded as a PL/R function inside the database, so the SQL generated the plot of the data (rather than just retrieving the data). The SQL created the plot & returned the filename of the plot it just created.

This worked on both a web site & from QGIS (QGIS on Linux & Windows both worked, but the script was a bit different on each)

HTH,

Hi,
