Notes on xmgrace

• Hotkeys:
• Ctrl L: Move current graph legend
• Ctrl M: Move an object
• Ctrl T: Place timestamp

• Set font color for plot legend
• Click on the plot and prefix the legend string by \R{red} (for red color)
• Transform axis tick label from length to angle in degree (acceptable expressions)
  atan($t/100)*180/PI
  
• Set the number of decimal digits to N on the transformed axis tick labels
  I had to multiply the result by 10^N and round it to an integer then divide by 10^N. For e.g. the following will set the number of decimal digits to to 2
  rint(atan($t/100)*180/PI*100)/100
