I have several codes that read in data from Excel files based on parameter mneumonics. Those mneumonics are used to search another Excel file for a more descriptive parameter name. For example mneumonic ADCIAS_PCM2 will retieve INDICATED AIRSPEED (KTS) as a plot axis label. That axis label is universal and I use it for my x-axis. I want to add text at each end of the x-axis for REARWARD (at the negative x-axis end) and FORWARD (at the positive x-axis end). The current plot goes from -50 to +50. I used the following lines and they work, but the problem arises if the y-axis scaling is different the text will be higher or lower relative to the x-axis. How can I add this text such that it will stay inline with the xlabel?
