Math.pow(2.71828182845905, a + b * Math.log(dbh) + c * Math.log(height_m)) / 1000 In this expression a, b and c are the extra properties of taxonomy. the value which had to take part with other expression. But it could not calculate the right value. Sometimes it calculates as blank cell, sometime 1 and sometime 0.01. It works fine if we put only taxonProp('trees','a',species) without messing other calculation. So, I created another attribute and put the right value using taxonProp('trees','a',species). Once the right value populated in the column it could be possible to produce the right value. I know, it is not a clever idea to do the work this way however it is working. In short, please, try to implement this type of expression like taxonProp('trees','a',species) X dbh or taxonProp('trees','a',species) X 10. (Here X is multiplication sign) Thank you very much. I am seriously waiting for the Arena update. |
