In this example, we will plot a sine curve and a hyperbolic sine curve in the same plot with a common x-axis having different y-axis. This is accomplished by the use of twinx() command. # Plotting tutorials in Python # Adding Multiple plots by twin x axis # Good for plots having different y axis ...

In this example, a plot with curves having common y-axis but different x-axis is demonstrated using twiny() method. Also, some additional features such as the title, legend, labels, grids, axis ticks and colours are added to the plot. # Plotting tutorials in Python # Adding Multiple plots by twin ...
