Trend Chart - Gaps or Interpolation

I'm looking for a technique that will display trend data WITHOUT interpolating (with a straight line) data between stored points. When I turn off "Allow Tag History Interpolation" I get gaps in my trend lines, even though trend history is active. Is there a maximum interval (Max Time Between Samples) tor the tag history configuration to prevent gaps on the Easy Chart?

I'm using Deadband Style=Auto, Deadband Mode = Absolute, Sample Mode=On Change

For clarity, do you have an example of what this chart would ideally look like without interpolation enabled? Also, how often is data being stored?
