I have a beast mode that takes seconds and convert into a duration, for example:  100 seconds to 1:40.  When I use this beast mode in a bar chart, it doesn't draw the duration.  Found a posting about using the duration text as label and tooltip for the bar chart while charting the # of seconds in the chart.

It shows great.  However, when the mouse flies over the bar, it toggles the labels to the seconds instead of the duration label.  How can I fix it so the chart will not show the # of seconds and always use the duration label.

With labels, it's showing the duration while the # of seconds is charted.

Here's a screen shot where the duration changed to the actual seconds when the mouse flies over the bar.
