Plot enumerated (string) data

String data is automatically detected and enumerated for plotting

Selecting Saved Plots

Each time a plot is created, it is saved under the Saved Plots section of the VSPlotter Plots Tree View within the Explorer tab.

• Click on the ✚ symbol to create a new plot from the same file
• Click on the 🗂️ symbol to open the file in a Grid Table.
