Confused.
A line with the coord pair of (-10,0)(10,0) will give you a horizontal line.
If you want a vertical line you will need a data set more like (0,-10)(0,10)

If you meant horizontal then as Mike pointed out your layout of data and
heading is being misread by the chart wizard.
Assuming data in range A1:D3 just select the values, B1:D3 and plot the
data in Columns. You will then get 3 lines of 2 points with the y3
series running along the X axis.

No, I used the XY scatter with data points connected by smoothed lines. I
did try with a line graph, but still can't figure out how to get a verticle
line representing x=0. My data points are below. y3 is y=0.

x y1 y2 y3
-10 9.5 29 0
10 -0.5 -11 0

Hi,

Sure that's not a Line graph (category X axis) instead of a XY scatter
(Value X axis)?

Hello,

How do I create a line through x=0 in a XY Scatterplot chart? I can plot
(x, y) and y=0 but not x=0. I am graphing linear inequalities and
identifying the feasible region for a mathmatics class.

Thanks for the help
