Analogous to selecting a time range, it is possible to zoom in on the vertical scale of a graph. Unlike setting the time range, however, this type of zoom will not be retained after its first use. To zoom in on the vertical scale, hold down the Control key and drag over the range you want to zoom in on. The next time you request a Graph or Strip Graph tool this range will be used to display output. This will not have an influence on later graphs because the vertical range is reset (to automatic scaling) after one Graph or Strip graph tool use. You can also set the Y-axis bounds using custom graphs.
