 ===== Carpet plots  =====
-Carpet plots do represent an efficient way for first visual data analysis. Beside classical carpet plot (or heatmap) we do use more sophisticated plots with aggregations. The basic principle is similar to pivot tables and pivot plots. User defines columns, rows and fold function. Each cell's value then represents aggregation of all values that do belong to the particular cell (e.g. average of of all values that were measured on Mondays between 2 and 3 am).

 ==== Electrical heating ====
 plots capture average electrical energy consumption during a week. In this case, electricity is used for heating, as can be seen from the first plot (horizontal axis: hour in day, vertical axis: month). There is clear start and end of heating season.
