For some reason, when I view the measuring block 001, wheel speed sensors, for the ABS unit for my VW T5 and then graph those values, the first value, (front left, G47), has a different scale than the other 3 values.

Which then makes it impossible for me to create a graph to compare all 4 sensors, and particularly this one, as it keeps throwing a mechanical error code, tho each time I glance down at the numbers while driving, all 4 speeds are the same, so not sure where the error is.

Max value for graph is 5 while others are 50.

Click on a field to select it for vertical scaling.Then change the Max and Min values in the Vertical scale boxes. VC-Scope will remember all scaling values for a particular control module by part number.

Are you able to select which lines the values will show on the grid? For instance, when i'm graphing measuring block 011, the requested and actual pressures start so high on the grid, I can't see most of the line as it disappears above. If they started lower on the grid I could see them...if they started lower around where the tach was you could see all three as you accelerate. I wasn't sure where else to ask this as I have been searching all over...TIA

Sounds like you need to adjust the scaling for those values. See post #3.

I tried, I have messed with the scaling and it does not bring the lines to the bottom of the grid...all of this is making me want to bang my head on the wall :banghead:
I have changed the min and max values and it does not bring the lines down. Someone please HELP!!!!

Please post a screen-shot like the OP of this thread did so we can see what you've got/done.

You don't paste it directly here, you upload it to an image hosting site (I use imgur) then paste the direct link here using the Insert Image forum editor tool.

I'm not sure what data it is you're graphing there, but those certainly aren't wheel speeds.

Well, you have two values there, 2508 and 2112, and two vertical scale maximums set to 2000. So it's entirely sensible that the graphs for those two values have gone off the to of the scale.

Change the maximum for those two to 2750 or 3000...
