I have data for some but not all days of a date interval. If I create a chart, dates on the x axis will be evenly placed. If I generate records with empty values, the x axis is OK but the chart shows the empty values as if they were zero. One possibility is to fill up the date interval with interpolated data but I wouldn't want to create so much fuss about a simple x-y chart. Do you have any idea how to do it in a more or less simple way? Thanks.
