So it's like a Gantt chart with products on the vertical axis, dates on
the horizontal, and usually with horizontal bars denoting some time span
for each product. Only you want some kind of indicator of RE, EX, FS, ETC.
You need to do a bit of work. I'm assuming it's already a gantt chart
with bars. You need to set up a range for each new series (RE, EX, FS
each are a separate series) that has a date and a vertical coordinate
for each point you need to add. The vertical coordinate is an integer
value, 1,2,3, where each number i refers to the ith item up from the
bottom in the list of products.
Before proceeding, right click the chart, select Chart Options, then the
Axes tab. Under Category Axis, check Category instead of Automatic.
Copy the range for each new series, select the chart, and use Paste
Special from the Edit menu to add the data as a new series. Right click
on the new series, choose Chart Type from the pop up menu, and select
and XY Scatter type, with markers and no lines.
Excel adds secondary X and Y axes, but often the new Y axis is hidden
under the primary X axis. Double click on the secondary X axis (top of
chart), and on the scale tab, check the Crosses at Maximum button. This
makes the axis visible.
Change the axis scale of this secondary Y axis so the minimum is 0.5 and
the maximum is N + 0.5, where N is the number of categories on the
primary category axis (left hand vertical axis). On the patterns tab,
check None for ticks marks and labels.
Right click the chart, select Chart Options, Axes tab, and uncheck the
secondary X axis. Excel will use the gantt chart Y axis as the X axis
for the scatter series.
You can either format the new series so each series has a distinctive
marker, or you can add the label to the points. Excel XP and later give
you a choice of Series Name for the label text; in older versions you
have to add value or label, then edit the text. You don't even need a
marker, you can format the labels and use the Center position (Alignment
tab), and the label serves as the marker.
