The SPC Charts with Alarming node has customization of line type, size, and color for Target Type but not for X Charts Control Limits, Specification Limits, nor variance warming limits. This makes it difficult to customize graphs so that are easy to look at and read effectively. Additionally, as a workaround, we generated SVB using a Master Macro while changing an X-Charts control limit line colors, etc. When using this SVB to customize the output of an SPC Charts node, the line customizations are not correct. So there isn't an easy workaround for this.
