How to make the datetime x axis not stretch

For the following dataframe I have plotted Day vs Correlation_coefficient go.Bar, expecting x axis will have 3 ticks representing the day and one bar for each tick. But in actual plot the x axis shows unwanted time as shown in the following figure. I just want it to display only the values given in the dataframe’s Day column. How can I do that?

          Day  Correlation_coefficient
0  2020-07-27                   -0.103
1  2020-07-26                   -0.029
2  2020-07-25                   -0.021
