The Line Chart displays data of one or more series as lines:

Line Charts

Expected Data and Graph Designer

The Line Chart expects data in a two (or more) column format such as:

23 January3824
24 January3924
25 January4024
26 January4024

In the Graph Designer you can then select the column you want to use for your x-axis:

Graph Designer X-Axis

Hence, the x-axis column does not need to be the first column. However, for consistency purposes it is recommended to always use your first column for the x-axis.

For each column, besides the one used by the X-axis one line will be displayed.
