Plot Line in data table

[Daniel Chalmers]

I have a table of data

8 9 10 11 12 13 14 15
1.00 28 32 35 40 47 59 71 82
1.50 42 47 53 60 71 88 106 123
2.00 56 63 70 80 94 115 141 184
2.50 70 79 83 100 115 147 176 206
3.00 84 95 105 120 141 176 212 247
3.50 98 111 125 140 165 206 247 288
4.00 112 128 140 160 188 235 282 329
4.50 126 142 158 180 212 265 317 370
5.00 140 158 175 201 236 294 353 411
5.50 154 174 193 221 259 323 388 452
6.00 168 189 211 241 283 353 423 493


I want to be able to plot a line through this for a specific value. Is this
possible. eg if i want a line for 120, excel will find best fit line through
chart. I want this to overlay on actual values as above.

Any help much appreciated.

Thanks

I'd use a surface plot, using the contour sub-type. Select the data table,
use the chart wizard, select a surface chart and the contour sub-type.

To put a line at a specific value (i.e. 120), select the legend and from the
menu click Format | Selected legend | Scale tab. You can put 120 in the
major unit box to get lines at 120, 240, 360, ....

Are you plotting a LINE or XY chart?
Which are the x-values in your data?
