Data points on x-axis are not properly displayed

Elastic Stack Kibana
1

I have two files with same fields.
File1:
Field1|Field2
0|10
200|40
300|70
900|100

File2:
Field1|Field2
0|10
100|40
400|70
1000|100

I am creating Line Chart to represent Field2 on Y-Axis (%Progress) and Field1 on X-Axis (Time in ms).
When I create chart data points are rendered abruptly on x-axis. Attached screenshot.

Is there any way to present them in order.

could you show your full configuration for the visualization builder on the left?
