What is the calculation used when charts determined the interval for the y axix major grid lines? I'm creating SSRS report which includes a chart. I want more Major grid lines than what is displayed by the auto generated. So I want to write an expression in the Major grid line interval. I can't use a set value because my data ranges will change. Example: Base on user selection values can range from -3000 to 4000 or 0 to 600. Wont know til run time. But with those two examples, I should have interval of 1000 for the first example and 100 for the other. What the auto generated lines are at 2000 for the first example.
So If I knew the calculation used, I figure I could write an expression. Thanks in advance
