i have used pie chart to represent a categories percentage value so i set Value labels as custom then select share but 2 categories are not showing their percentage and when selected only both of them i found that their percentages is almost lower percentages however i need to have their percentages shown without using selections.
It would help for you to play with the axis ranges. My personal rule is that if there are more than 5 categories/topics, or if the data has such low extremes, for us to revert to a bar graph instead.
First try and play with the ranges in the axis and if not, I would recommend a bar graph instead.
This is a decision you would have to make based on how better to project your data. It is the same as having a bar graph across 60 days for each day on the x axis. It would messy, But if you used a line graph instead, it projects better.
