@Samir Khan Thanks, yes that works.  It is strange that there was no error reported, or that the graph still displayed when one of the options was wrong.

Is there a way to display the units for the axis too, or do I need to add that to the axis title myself?

@Samir Khan thanks for the work around to solve this issue.  Though I will be honest, I would like to be able to use the symbolic representation of the equation using math symbology, as it is easier for people to understand what is going on if they are not familiar with Maple Flow.

Is this a bug, and is it something that I can look forward to being corrected in the future?

Best regards

@sand15 Thanks for that.  I am using Maple Flow, and the purpose for percentages, is that I would like to be able to let the people using the sheet, to be ablt to enter the value as a percentage.

The value that I am interested in, is a volume percent, i.e. the percentage of the total volume is 10% of element A, and 90% element B.  it is easy to convert to fractions when it is large numbers, but the number of 0's can confuse people when you are talking about 0.03%.

In effect, I would love Maple Flow to be able to understand percentages, the same way that I can type in an exponent, and Maple Flow understands that too.

@Kitonum Perhaps to better explain my quandry, I have two different pipes, where I measure the radius at 1/3 degree intervals around the entire internal diameter.  Because I can not be certain that the centre of the pipe is used for each pipe measurement, I would like to be able to vary to origin of one pipe relative to the other, then perform a check to see if the line-up between the two circumferences is better or not.

So basically I want to be able to translate the origin of the prescribed circle, then calculate the new radius measurements based on the original origin point.
