Often, there are null values in the data fields of a data table that you bind to FlexChart for plotting data. Due to the presence of null values, FlexChart creates gaps once it has plotted the data. The gaps present in the plotted data make data look inconsistent and incomplete.

FlexChart allows you to deal with such inconsistencies by using the InterpolateNulls property. You can set the InterpolateNulls property, so that the chart automatically fills in gaps created by null values in data.

Here is how you can set the InterpolateNulls property:

FlexChart1.Options.InterpolateNulls = True

flexChart1.Options.InterpolateNulls = true;
