Thank you again.
Originally , when the scale is in "v" ( volts) the graph shows an horizontal line ( as en there is no pedal movement = 0 Volts) and when depressed it shows a reversed spike ( spike that reaches 5 V. and goes from the horixontal line --> down instead of what will be expected: "up" for more V, "down" for less)
I have followed your instructions. Tried several times and checked. Tose are the (new) results:
1.- THe X scale now shows a minimum of 0.16 and a maximum of 0.36
! instead of 0-5 V.
2.- The ( previously) horizontal line has changed into a series of short and compact spikes of similar dimensions ( instead of a readeable single horizontal line ) and the previously reversed spike now is a Bigger spike that NOW goes in the apropiate direction :goes form down -->up.
3.- Before pressing the "Calculate formula form values" I took special care to delete any sign, letter or value under the box "custom".
4.- After introducing 0 under "input volts" and 100 on the same row, as well as 5 and 0 on the following row, I clicked OK, etc...
5.- The graph changed as described before.
6.- When going back to the
Data > Variable Manager > External Inputs > Analog1 (for instance) then Sensor Type / Units and Custom:
It NOW shows the following:
Temp(0) * x^3 + (0) * x^2 + (-20) * x + (100)
7.- I have never added the initial variable "
Temp", and the Analogue Chanel 1 corresponds in my variable manager to the accelerator chanel that I have named "GAS"..
In conclusion: the graph , and numbers have reverted ( now the spike goes from down-->up as are the numbers in the X side ) but the scale is weird as is the graph which ahas become far less readeable..
...
Please, help me with instructions as simple as possible. I am already struggling with the instalation ..
