In CSS BOY, using the XY Graph to show a strip chart, I want the X axis to show the time relative to the most recently acquired value.
Say I have a Y PV that is plotted, and a trigger PV that updates at a constant rate (1 second), new data points are plotted every second. I set the buffer length to 15 so that only 15 seconds of data are visible at any time. The horizontal axis (time) increases as new data points arrive. I want this axis to, instead, range from -14 to 0 and stay constant. How is this done in CSS BOY?
