Thank you so much. My English is not good so I didn’t read document well. Please help me last question. I follow this tutorial to custoom tooltip content. https://canvasjs.com/docs/charts/chart-options/tooltip/content-formatter/ I got y value as well but I don’t know how to take the percent of y value . Does canvasjs provide it or I have to callculate it myself. Best regards
Thank you so much, Indranil Deo. But I want to add one more question. When I calculate total of column, result will display inside column if the column is too high. You can see my promblem is this example: https://canvasjs.com/docs/charts/chart-options/data/indexlabel/. How can I make the result always on top and outside the column. Best Regards.
