I'm using Qgis 2.2.0-Valmiera 64 bits, on MS Windows 7. I'm just getting started with Qgis, and GIS in general.
I'm trying to create a map similar to http://nadp.sws.uiuc.edu/maplib/pdf/mdn/hg_Conc_2011.pdf, with updated data, and for Kansas only. I have data in an MS Excel spreadsheet; I can import that to QGIS via a .csv intermediate. Now I need to convert that point data into a color gradient. I found the algorithm Processing | Toolbox | Models | Example | Contour lines from points ; that seems like a good first step. However, when I try to run it, it produces an error message. I can't read the entire error message, because the window closes. More precisely: load the project with the data double click on Processing | Toolbox | Models | Example | Contour lines from points Keep the default selections; in particular, "open output file ..." is checked. click Run An error dialog pops up: title "Problem loading output layers", text saying "file ... cannot be opened ...". I can see part of the error message in the "Contour lines from points" window, but I can't scroll to see the rest. When I close the error window, the "Contour lines from points" window also closes. If I uncheck "open output file ...", the "Contour lines from points" window closes immediately. 1) Is there a way to keep the algorithm window open after failure, so I can scroll to see the entire error message? 2) This appears to be running a command line executable in a sub-shell; how do I find out what that executable is, so I can try to run it directly? 3) Once I get the contour map, what algorithm will convert it to a color gradient? 4) Is there a better way?
