I am attempting to create an UltraWebChart line chart that has three series. One of the series is an average that does not start until the fourth data row. For those first few rows the average is considered null. The chart is inserting values of zero for those points that should not be there. It makes it look like the average climbs from zero when in fact it should start in the middle of the chart. How can I get the chart to treat null as null?
Try using:
this.UltraChart1.LineChart.NullHandling = NullHandling.DontPlot;
Thank you, I have been searching all over the internet and the user guide for this. I never looked at the LineChart property. Live and learn!
