keeping it simple
i understand the combining of 2 charts, but that is not this case...
I am asking about the creation of one simple chart that will take a single value (dynamic in this example) and making a single horizontal line across the entire chart to represent that single value.
Most charts have 2 points of reference (e.g. time vs value), but I am interested to make a chart that has only one point of reference, which is the value. The "time" should fill the chart entirely even though there is no time reference available in the dynamic data.
