log scale axis for charts
-
i am attempting to develop a custom control and got somewhere with the linear scale axis. how do i go about creating a log scale? is there a formula that dictates the spacing between ticks or i have to keep some sort of normalized table that stored relative tick to tick units and use that to do translation. if so, is there such a look up table? use to refer to a log table handbook before the calculator came along. hope some kind souls or chart control developers can give me some pointers.. thanks huikm
