Via HTML (Portlet), available starting with TIS 7.0. The Heatmap (Plotly) provides an way to display long data series in a very dense form:
The base data of a heatmap needs to be prepared in a Data Node first to contain one column for X-Values (here: "Mon 00:00" or "Sun 21:00"), at least one column for Y-Values (here: "Leisure" or "2020, 02") and one column for the numerical value.
This data needs to be added as a hidden Simple Grid (Portlet) or Editable Grid (Portlet) to the same page as the Heatmap portlet:
Create a HTML portlet (with a dummy HTML node) and connect this newly added grid portlet to the Heatmap. The file heatmap/index.html is part of TISBoard.
After that, you can adapt the settings of the heatmap (color scales, ...). Note: changes are only visible on the dashpage, this means you need to save the heatmap and switch over to the dashpage containing both the heatmap and the data grid.
