We need more information about your scenario in orther to help you:
- Data Topic using (I assume in your case it is FastDDS Latency)
- In historic plots -> number of bins and statistical function (e.g. AVG)
- In dynamic plots -> time interval and windows size
- Is your network stable? How fast is your connection and how many Participants do you have.
I suggest you to check our online documentation, specially the section of Data plots: https://fast-dds-monitor.readthedocs.io/en/latest/rst/user_manual/chart_panel_index.html
My notion with the information we have is that you are using RAW statistical kind and / or bins 0, so the points that are plotted do not follow a logical order, but are shown as they arrive from Fast DDS external Participants.
Helllo, when using the monitor to display historic or real-time statistics, the time interval is not followed by the monitor: the data interval is not consistent, sometimes the interval can be very large, eg 2 min, even thought i set the time interval to 5s, please see the screenshot. Is it because the network or because of the monitor itself?
