first of all, happy and prosperous 2018 to all of you!
I’ve been struggling with displaying historian tag in a way our users want. Here’s our setup concerning this tag:
- historian tag has scanclass
- the tag can change its value not often than each 2-4 minutes
- I’d like to depict it in easychart with line w/ shape
Problem is, that the phase, where the tag value is constant, is crowded with shapes (namely square), See attached picture, please. What I want to get is, one shape per change of the tag. How can this be achieved? I get lot of squares on the horizontal part even if displayed time range is in seconds.
Following the chart (please observe the horizontal parts of the khaki chart - crowded with squares):
