Can Not Visualize the signal scopes in Vehicle Network ToolBox

I am having issues regarding visualization of signal scopes , I followed the tutorial of receive and visualize CAN data and I used a dbc file from a github repository but after i add it in the database and set the signal scope and run it , it does not visualize the graph it just shows the graph running with respect to time as mentioned in the picture i have attached, I tried the test database file of can explorer as well it is having the same issue so are the other dbc files that i am adding to the database , I will add the link to the github repo from where i am taking these dbc file, link: https://github.com/ajouatom/canbus-tools?tab=readme-ov-file#dbc. If someone can help me why i am encountering with this issue would be greatly appreciated.

Hi Jay,

I understand that you have loaded the DBC file to the CAN Explorer, configured the signal table, configured the signal scopes and tried to run the explorer. The issue here is that there is no CAN data for the explorer to visualize, due to which the message table, signal table and the signal scopes are empty.

Please refer to the following documentation for detailed steps on how to visualize CAN data using the CAN Explorer: https://www.mathworks.com/help/releases/R2023b/vnt/ug/use-can-explorer-data-reception-visualization.html

The CAN Explorer is configured to receive data using "MathWorks Virtual 1 Channel 1" by default. Pre-recorded data is provided in a MAT file and replayed onto "MathWorks Virtual 1 Channel 2" to emulate CAN traffic generated from connecting to an actual vehicle system by running the "replayCANData" MATLAB script specified in the above mentioned documentation.

Follow the steps and once the monitoring is started, run the "replayCANData" MATLAB script and you will be able to visualize the CAN data receive on "MathWorks Virtual 1 Channel 1".
