Hi,
As per my understanding, you want to draw multiple charts corresponding to a common X axis. Please note, C1Chart supports secondary Y-axis. It has two chart groups: Group0 is plotted against Y-axis and Group1 is plotted against Y2-axis.
Please refer to the following documentation link showing how to implement two Y axes in a Bar Chart:

You can also draw lines in the plot area of the chart depending on the coordinates or data points on the X and Y axes:

You are requested to elaborate on your requirements a bit further if this is not what you are looking for.
Thanks and Regards,
