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