> Power Chart - Set X-Trace tag labels to their pen colour This will set the tag labels and values shown in all x-trace panels to the colour of their chart pens. The script (dodgilly?) grabs the colours from the legend key at the bottom. I haven’t tested if this works when the legend is collapsed into the smaller version Instructions Copy and paste into a View with a Power Chart and your operators will no longer become frustrated trying to eyeball x-trace tags with their corresponding …
