Is it possible to align the zero lines and grids of Plots with different scales automatically on the same ChartView?
Thanks in advance |

| Sorry, but I don't know what "align the zero lines and grids of Plots" means. Please explain in more detail. |

Say that one has a dataset represented as vertical bars in dollars
and a dataset represented as line plots in dollars (but in a different magnitude, e.g. the bars are from -500 to 100, and the lines are -1,000 to 10,000) that should be overlaid on the bars.
The maximum and minimum values for each of these two datasets are non-equal. Therefore, when they are plotted on the same ChartView, the zero-lines (where the datasets cross zero) for each dataset are not aligned to the same screen coordinates.
What I would like to do is to align the zero-lines (and the grid spacing) for each dataset to produce the effect of a combined graph with a common zero, but disparate scales.
What I want to know is whether this is possible automatically, or whether it is required to perform the calculations externally and then force the vertical scales of each transform to the required maximums and minimums. |

| The software auto-scale and auto-axis routines do not contain any features that will align axis zeros, ticks marks and grids across multiple, arbitrary, coordinate systems like you describe. |
