XY Graphs

[Vinod_Mathews]

Hi,

I am acquiring data from strain gauges and then calculating the damping
factors.
I then do a general polynomial fit on the data and plot damping Versus
frequency on an XY Graph.
1. I need to mark the actual calculated damping values on the same graph
as say dots or crosses on the graph ( in some cases it may not exactly
be on the plotted curve - as I am recalculating all values of Y
(damping)based on constant delta X(frequency) depending on the coeffs.
generated by the gen. polynomial fit) Is there a way to do this?

2. How do I print such a graph on to a deskjet printer connected to the
parallel port other than through print window?

Thanks in anticipation
Regards

It sounds like you need a multi-plot XY graph. Build XY graph
data types (cluster of X & Y arrays) into an array and wire it
to the graph. One plot will be your original calculated data
and the other will be your fitted data. You can turn off
interplolation for the original data so the points are not
connected by lines. Right mouse-click on the plot legend and
select "interplotation", you'll see a choice that shows points
with no connecting lines. Do the opposite for your fitted
data. Turn on interpolation and set the point style to none.
The effect will be a line for the fitted data and points only
for the original data. If you need help with the multiplot data
type, turn "show help" on and pass over the graph in the
diagram. The help window will display examples o
f the data type.
