chart.addTo() method is used to add the line dataseries programmatically, as shown in the example. The code you are trying does not work because the series needs to be created before “type” or “datapoints” can be assigned.
If you are looking to change the y-values such that the line is centered vertically, you can use the y-axis range to calculate the midpoint. In case you are still having issues, please create a JSFiddle and share with us, so that we can understand your scenario better and help you out.

Setting legendMarkerType as ‘triangle’, and legendMarkerColor as ‘white’ seems to be working fine, and creates a dashed line legend marker. You can take a look this JSFiddle for the complete example.
If you are still facing any issue, please share a JSFiddle reproducing your use case, so that we can look into it and help you out.

Since the two charts have varying number of dataseries, there is a difference in datapoint width. You can use dataPointWidth property to enforce the same column width across the charts.

Datapoint width depends on multiple factors including range of x-axis, number of dataseries, sequence of datapoint values, etc. Sorting the data by x-values should work in your case, and give you columns of similar width. Please take a look at this updated JSFiddle for an example of the same.

Sorry, it’s not possible to move the toolbar using any property as of now. However, you can use CSS to style it, as it is a DOM element, and change its position. Please take a look at this CSS snippet for an example on how to do the same.
.canvasjs-chart-toolbar {
top: -50px !important;
}
