Graph does not plot all values, horisontal axis have dates with multiple time points

[AmalieM]

Hi all,

I am trying to make a graph for two data sets. The sets are logs of temperature and relative humidity, measured every 15 minutes for two weeks.
I have problems with the graph, when I do not select the yyyy-mm-dd hh-mm-ss as the horisontal axis, it shows all data points. However, when I want to show the dates and times on the horisontal axis, it only displays one value for each date, thus not the entire data set for every day.

Has anyone encountered this problem before and know how to solve it?

Cheers,
Amalie

You need to use xy-scatter chart as line charts only have day accuracy when scale is Date.
