Re: I could not see values on data points in Gauge chart
The gauge chart doesn't have a Values on Data Points option. You will have to use the Text in Chart option on the Presentation tab. Use as value for the text option the expression of your chart: sum([my field]). Once you've added the text object you can move it by pressing the ctrl+shift keys at the same time. You will see red outlines of parts of the chart. You can use the mouse to resize and move these outlined boxes.
