Berk, I am trying to construct a 24 (hour) by 365 (days) plot of energy values generated from a simulation and stored in SQLite.
The query that constructs a data table with the the three columns for plotting is: select [hour],(([Month]-1)*31+ [day]) as y, variablevalue from reportmeterdata rmd join timeindices ti on rmd.timeindex=ti.timeindex where recordindex=157 group by [month],[day],[hour] This is used in the SQLDatabaseTableSource plugin and construct a table with the [hour], y and variableValue columns from the database - the plugin adds the idType fourth column. Then I use a TableToPoints filter to construct a Polygonal Mesh with 1 cell with the correct X range (=[hour]), Y range (=y in query above) and variableValues from the query. I then try to construct a contour using the variableValue but that is not an option in the "Contour By" property of the Contour filter. I will try the Delaunay filter but need a way to script these data views and to compare the results over multiple SQLite files - can Paraview accomplish this?
