Hi,  
I want to use a binding -\> tag history to display the value of that time I choose. In the binding I get a dataset but I wan't only the value and not the time with it. Is it possible with a expression?

Yes, just add a transform and extract that value out of the dataset : `value[0, 1]`

Should be `value[0, 1]`, presuming the timestamp is the first column.
