Dear Daniel, Thank you for the cleanning. I am sorry if you find many mistakes.
In fact, to draw this chart I followed this document where datatable is a matrix where the first coloum must be a string: https://developers.google.com/chart/interactive/docs/points#fullhtml However,before using ajax and json (for the dropdown event), I put my data in a php function and then I call it back in my web page and I can get both axis in logscale. Unfortunatly, it doesn't work using json format. here is the output.
