hi.. wasnt really sure where to put this or what to search for.. hopefully someone will have some clue what im waffling on about

basically, i have a table of data which is 14x14, and i need to put that data in my table which is 12x12.

the data is ignition advance values for my car, with RPM along the bottom and MAP up the side.

The max and min values on each scale need to remain, but i need to recalculate all the points in between.

Current scale goes up in 400rpm chunks, new one in 550rpm chunks

What i was thinking of doing was plotting a column of data at a time, individiually and then using the graph to calculate what value i should have 550rpm, 1100rpm etc

I tried using excel for this, but it won't tell me intermediate values.

Anyone know any software that would, or im going to end up printing the graphs and getting my ruler out!!
 
i dont think that'd work, there is no trend on the graph, the gradient varies, and it isn't constantly increasing decreasing.

hmm!
 
i dont think its an anything, there is no relationship between the two scales - it is a settings file, an ignition map for my ECU..

i was only look at making a graph out of the colums so i can calcuate the intermediate values between the RPM points that are shown.
