Dear Damien Thiriet, If you change ‘vardef’ to ‘def’, you will get the figure. There is a difference between ‘vardef’ and ‘def’. AFAIK, vardef returns the value of the last statement in the macro. Please see the examples in Metafun manual from page 32 ~ . I hope that you find your answer there.
I am sorry that I am not good enough to explain the variables.
