The premade line charts require different width space between each other depending on if they have text boxes for "Points of interest"(__todo__ link) attached. If they don't have these text boxes, or if only pie charts are used then the charts can be grouped more densly together, which eases comparing different neighboring charts.
Though if the text boxes are there they intersect each other and are not readable any more when grouped in a dense layout. With this function you adjust the distance between the premade charts according to your use case.
If you deactivate the collectively used rotation pivot point by setting premadeChartThatIsRotationPivot to "-1" then the distance will only meet its intention (namely "_needsPointOfInterestTextBoxesOnOneSide") when looking along the global z axis.
