This requirement "how to add dashed and don’t show a line between marks" can be achieved by using theonCreateRenderercallback that is available in chart series. To render a dashed line for the specific segment using the current segment index value, the existing line series renderer class can be overridden with a custom line series renderer class to get all series segment index value. You can also achieve the space between the points by using empty points.
You can refer the below attached sample along with user guide documentation for more details about onCreateRenderer callback.
