I'm investigating displaying graphs for different timezones than their data was collected in. For example, if the data is collected in GMT and the user selects CET (GMT+1) for displaying the graph, I want all graph data to shift +1 hour.
As far as I can see the only way of doing this is shifting each individual vname in a graph using the SHIFT instruction (http://oss.oetiker.ch/rrdtool/doc/rrdgraph_graph.en.html). This does involve quite some programming if there is a fairly large number of variables.
Is there another (easier) way of shifting all graph data?
