data collected at different time interval but shown as if at same time interval

[Qianru221]

As shown in picture above. I plotted a line graph and turn it into dots since I dont want the dots to be connected.

My problem now is that when I drill down the data, not every day is shown on the x-axis (which is what I want). It will be still ok if the shown dots are correctly spaced. For example, the data of August 19, 22, 24, 25,26 are equally spaced, which created a false impression that the dots of data are collected at an equal interval of date, which are not.

Thank you in advance.
