How to display the x-coordinate of a point on a plot? [message #1389206]

I am trying to design a report model in BIRT in which there are several date/time series charts that share the same x-axis (multiple charts that correspond to the same date, but each have their own independent y-axis definition).

To establish that they all follow the same x-axis, I was thinking of making a separate chart at the top with only the x-axis showing. However, I need the actual dates themselves to be displayed, not a range with increments that the axis labels usually have.

I can generate a chart that looks like a datetime series with the points themselves, but I don't know how to extract the actual x-coordinate out of the point. Is there a way to access and display that value?

Here's an example of what I mean (can't post a direct link because I haven't posted enough yet on the forums):

What I'm trying to do is extract the x-coordinate (i.e., the date itself) from the point and use that as the x-axis label, instead of the range of dates with ticks at fixed increments.

Is this possible?

So, you would like to have a chart that displays the actual dates of each point in the x-axis rather than the range shown in the image linked above? Let me know.
