I made and worked. only the range of scaling is -220 to 980 for 0-10 bar and when the pressure 0 bar in the display reads -2.20 bars. while, for 4 bar correctly displayed in the 4.00 bar display.

can anyone help me how to make that when the pressure is 0 bar and show 0 bar on the display

You have the wrong sensor settings.

Your sensor has a measuring range of 0-10 bar and outputs this as 4 to 20 mA.
Parameterization of the analog amplifier:

Sensor type: 4 ... 20 mA
Minimal: 0
Maximum: 1000
Gain: 1.25
Offset: -250
Decimal places in the message text: 2
