This is the intended behavior since we don't know which lines we need to draw otherwise, all the datapoints are in a single dataset and then we draw a line through each point in that dataset in order of the entries.

If you only want the horizontal lines you either need to write a custom plugin to draw them or put the values in separate datasets.

You have the option showLine set to true this will draw the line between the points. If you remove this option or set it to false it will disappear:

@LeeLenaleee
I am still using showline to draw straight lines, but why do I only draw lines from A to D and B to C, but line from B to D appears?

Can you explain it to me?
