A Value X-Axis and Category X-Axis would display the data differently:
The fundamental difference is a Value-Axis uses the X-Value to compute distance on the XAxis, whereas a Category-Axis uses the X-Index. Value-Axis are primarily used in scientific software where Category –Axis are typically used in financial software (e.g. stock charts).
SciChart features both Value-Axis and Category-Axis types.
