Hello User92:You can use the InitializeHidden attribute to instruct the chart to intialize all non-initialized values to a hidden value. If the InitializeHidden attribute has been set to true, you can then use another attribute called InterpolateHidden, which instructs the chart to draw a connecting line over hidden data points. If the InterpolateHidden property is set to false, hidden points in the chart will result in a "broken" line in the chart. When set to true, the chart will connect the points thus preventing the broken line.Examples:Setting the non-initialized data to Hidden:chart1.Data.InitializeHidden = true;To instruct the chart to draw connection lines over hidden points:chart1.Data.InterpolateHidden = true;I hope this helps.Regards
