charts with new variable
Hi! I want to create a chart to show the evolution of the mass of a component in a room (Mass of the component - Time). I can obtain the mass for each step with the function volumeInt in the Function Calculator but the menu of the chart asks me for an expression. What should I write there? I've tried with:
where Product makes reference to the density of this component. But it hasn't worked. Creating an expression with the same hasn't worked either. Does someone know why? Thank you!!
