For linear regression it is in issue 34093. Do you think of other types beyond linear? Yes, forcing the y-axis intercept to zero is applicable exponential curves as well as the polynomial regression I proposed in Issue 77930. Forcing to zero makes no sense for me for exponential curves. But if we get polynomial regressions, it might be a useful feature. Hope, it goes to chart now. I am sorry. You are correct about forcing to zero not making sense for exponential curves. However, Excel allows the user to force exponential curves through values greater than zero, so including that option in Chart would be appropriate. @Iha: maybe a good idea. I agree. This is very important function for me as a science student. I can't stop using Microsoft Office until I can do this in Open Office - at least for linear regression. In fact in the interest of flexibility I think you should be able to choose exactly where it intersects either axis. I know there are scientific arguments for and against this function but what difference does it make who is scientifically right or wrong. If this is a function that users want to use then Open Office should be able to do it as simply and quickly as possible. Its also necessary to be able to extrapolate the line as much as desired in either direction. |
