Hi,
I went through the project attachment keen to discuss further on the requirement. The .csv file has these variables i.e. "VarName","TimeString","VarValue","Validity","Time_ms".
Assuming TimeString" will be on x-axis, can you help to understand how you would like the other variables to be plotted. The skill set says VB.Net /C#. It is correct to assume that you are looking for a desktop application either in VB.Net and C# to achieve the end objective.
Looking forward to your response.
Thanks
