Range with positive numbers

I am developing a questionnaire for HPA. The answer has a range between 9-0-9 in order to compare variables. However it only accepts if the left side of the range has negative values. Can I fix this error and keep all values positive?

Can I also put text at the end of each bar side?

Thank you very much

The error is the following:

  • RangeError: Invalid array length

Welcome to the community, @ncangi! Shouldn’t this be as -9 to 0 to +9?

Thank you. Yes, actually the form is -9 0 +9 but it can be confusing to people because we are comparing one variable with the other. Thank you.
