This setting allows you to define what policy is used for situations, where you have no data for the corresponding point. Most prominently noticeable when used with chart types "Line" or "Area"

Currently available options are:

• Join - Connects the 2 closest/available data points disregarding any missing ones
• Zero - Forces the points that have no value to go through the 0 on value axis and the connecting line to go through it. and
• Skip - Removes the connecting lines for points that have no data points, if columns are used it will just skip a column, but when lines or areas are used note that you need at least 2 points to see connecting lines.
