In scatter chart, the "Log" option is available in Scale Type property. You can use whole numbers in the resource data and seeing the option to change the scale from linear to log(please review the highlighted in yellow backgroud).
Log scale type is not available in bar charts and column charts currently based on my research.
The command R statement and create R visualization. The logarithmic scale can be used in R stament. For example, you can use ggplot2 function.
For some visuals, the Log option will not appear in the Scale Type drop down until after you override the Start value to be 1 instead of Auto
Log scale is now available on column and bar charts, but I also just hit that wierd little snag where the log option doesn't appear until you set the start value to 1.
I found this thread by trying to overcome this very problem... For what it's worth, I now realise that it's not just values of 1 that you need to enter... Any non-zero value (other then 'Auto') will work... Just type in any suitable number.
