Nothing ... there is no difference

Hi Kiran, so far I know in chart expressions there is no difference. In other objects like text boxes it's a must-do if you want to calculate something. It also can change the behaviour of a variable.

In big terms, when an expression starts with '=' the expression returns the calculated result, when you don't have that preceding '=' it returns the string. As charts expressions is used to calculate the result, there is no difference using the starting '='.

Hi Kiran,

In First Chart: Year as Dimension and Sum(Sales) as Expression

Create a Variable vSales and assign the value as =Sum(Sales) in Variable Overview Window
