Chart for Dial Gauge Calibration

Hi, we're implementing online document for our calibration certificate & raw data
for dial gauge. The problem we are facing due to dial gauge have different interval
at some measurement (example : 0 ~ 2mm : smaller interval 0.1mm, 2 ~ 2.5 : 0.5mm).
I have tried to adjust the chart but cannot match with the original on hard copy sample.
I attaching the sample sheet for reference.

Thank you
