I am using a gauge widget and HDV for trending a tag from a modbus device.
The scan interval is set for 60 seconds, i want to keep the last read value until the next read in order not to have gaps in the HDV trend line. I am using the following settings:
Despite those settings i am still getting gaps in the graphics.
I have tried to use the "Hold" option in the SERIAL tab, but the trends will freeze on a certain value, even the gauge is showing variations.
What am I doing wrong ? (The goal is to have continuity on the trend line between the readings, the only scenario for having gaps will be on transmission error)
