Just like the native line chart in Qlik Sense it is possible to change whether to show the labels or title on axis. There are also options to change the label orientation between horizontal and tilted.
On the X-Axis there are options for changing how many X-values the line chart could have. Either all values are shown, or a maximum of values can be set.
For the Y-axis a range can be set for the min and max value. There are also options for an inverted y-axis.
For using the secondary axis, the option "secondary axis" need to be enabled in the measure.
The legend can be enabled or disabled.
