FLOATCOL.OTP (installed to the Origin program folder).
The floating column graph displays Y values as beginning, at one or more intermediate (optional), and ending column levels for each X value.
The first Y data set provides the starting Y position for each column graph. The second Y data set provides an intermediate level and defines a column between the starting position and the current position. The third (fourth, etc.) Y data set provides an additional intermediate value and defines a column between the previous intermediate value and the current value. The final Y data set provides an ending value and defines a column between the previous intermediate value and the current value.
