Finding best fit distribution and its Parameters

[shegal]

Thanks to EnumaElish for helping me in Normalizing the histograms. I now want to find the best fit distribution and what will be the parameters for that distribution. I tried lograthmic but it goes in negative and also is not much fit (the new plots are attached). If I use poisson what will be the parameters. Please help me in finding the bestfit distribution and its parameters.

I'd try Log-Normal, per my previous advice.

How would you do this in excel.

Define Y = Log(X) where X is your original variable on the X-axis (apparently goes from 1 to 365 or so). Then plot the associated frequencies (of X) against Y. Excel might have a plotting option that let's you express either axis in Log form; if so, you can select that option to logarithmize the X axis.
