When the x-axis is the timeline, there are some problems that I don't know how to solve echarts

the type type of the first image is time, that is, the timeline. It is found that some of the time rendered by the x-axis is automatically generated by echarts. I do not have this time for it. Can the time automatically generated by echarts be deleted?

the type type of the second chart is also the default date and value displayed by echarts above the time, bar chart. I just want to display the value. How to do it
