Power vs Temperature Graph

Question

I need to plot power/current  vs temperature on a graph from data collected by another program.  The program runs from -10C to 60C, back to -10C, then goes to 60C, and finally returns to 25C.  The collecting program stores time, temperature current, and power.
I would like to plot power/current on the y axis and temperature on the x axis, but maintain the time reference.  Basically I would like to see the x axis read
-10 -5 0 5.....55 60 55.....5 0 -5 -10 -5 0 5.....55 60 55...25
When I use PlotXY or PlotLine the x axis plots -10 60 and the y axis plots back on itself.
We can do the graph in Excel and have attached a pdf of a plot.
Solved!

Paul,
I am not sure I got you right - could it be that you didn't read my post carefully enough? In the line
InsertAxisItem (panel, PANEL_GRAPH, 0, 10, item_label [10], 10.0 );
the 10.0 is not meant to be your temperature, but the (double) index of the respective array element. This way the x axis values of your graph are monotonously increasing from left to right, but nobody knows because the x-axis values are labeled with your temperature values... So if your tenth temperature is +20 and your twentieth temperature is -60 degrees, it will be displayed in that order and the graph will not put 'the minus temperatures and their labels to the left of zero'
 (One might argue that item_label [ 10 ] should read item_label [ 9 ] but this is a cosmetic issue...)
