<div>Hi Anita,</div><div>I am glad you find some use for it!<br></div><div>I did choose SpatiaLite since I deal with quite a lot of data from several sites at the same time. </div></blockquote><div><br></div><div>Are you using any of SpatiaLite's functions?

</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;"><div>It turned out that spaialite is a great data container for me and my colleagues since we only have to deal with one single (and portable) db file for each site. Furthermore, since we are mainly hydrogeologists and for sure no db gurus, spatialite seemed lika a much easier way to start organizing things than e.g. post-GIS.</div>
</blockquote><div><br></div><div>There are some reasons why I don't use Spatialite much, e.g. the combination of QGIS + Spatialite has some issues if you define database views and try to import them into QGIS. The data types are screwed up often, which in turn makes it impossible to visualize the features by their (numerical) attributes.</div>
<div><br></div><div>Once PostGIS is set up, I've found it to be much more reliable and predictable than Spatialite. e.g. Spatialite's weak typing lead to unexpected results.</div><div><br></div><div>Therefore, I'd suggest implementing support for other vector formats available in QGIS before building new features. A broader setup will attract more interested users and possible developers.</div>

<div>I also hope that I (or anyone else that finds it interesting) will get time to extend the plugin to include more ways of visualising other hydrogeo data from the same spatialite db. Additional functions would be stratigraphy plots (similar to ARPAT), time change visualisation (as your Time Manager), gesection profiling, some R statistics etc. (Could be a lightweight alternative to the core functionality of ArcHydro GW data model and tools.)</div>

<div>Looks great! I'd have quite a lot of use cases for such a plugin.<br></div><div>Any specific reason why it's limited to Spatialite as a data source?</div><div><br></div><div>Best wishes,</div><div><br></div>

<div>Fellow QGIS-Users!</div><div> </div><div>I just finished my first QGIS python plugin in an experimental version.</div><div> </div><div>The plugin uses pyspatialite and matplotlib to load data from a sqlite database and plot it by matplotlib plot command. The intended use is for e.g. hydrogeologists (i.e. me) to quickly select features that corresponds to observation wells, stream gauges or other measuring stations with data to be plotted and then quickly (yes I am in a hurry) have a window with time series plot for zooming, panning and visually examine the data (I know it is not very scientific but I do perform some serious data analysis at a later stage...). </div>
<div> </div><div>Anyway, the plugin is named TimeSeriesPlot, marked as experimental, and found in QGIS User-Contributed Python Plugin Repository.</div><div>Screenshot: <a href="https://docs.google.com/open?id=0B1vhrFUx2OZBODQ5YjJjZjgtYzkyNC00NmQwLWFiYWQtNjkzYmE2MGY0MzY4" target="_blank">https://docs.google.com/open?id=0B1vhrFUx2OZBODQ5YjJjZjgtYzkyNC00NmQwLWFiYWQtNjkzYmE2MGY0MzY4</a></div>
