How to make space in xy chart

Please tell me how to make blanks.

try negative numbers for "blank" and have your yAxis[0].value.range.min use a value of 0.

Odd for loop

Something looks strange to me. You seem to be passing in a single dictionary and then treating it as an array in the for loop. I've never seen that syntax (inside an array) either but I have a tremendous fund of ignorance regarding Python.

Were you able to solve this?

I don't do it that way, I just create one more data on the y-axis

And it was added to the series and made invisible.
