Editing and customizing Legend on a line graph

Hi everyone. I’m using Giraffe library to display line graphs and I had a question about the dynamic legend that shows up (for each data point) on the graph.
Is there a way to remove or rename the heading for each column image below? This is what my dynamic legend looks like - For now I’m trying to remove headers in those three columns ("_time", “_value” and “cbQosCMtype”) and just display the data only
LegendName

I did read the Documentation on Github and tried out different properties but I was not able to get the desired results I was hoping for.

Kind regards.
