To specify how the order influences result.
Chart elements are based on the order - first place means it will be rendered at the top 'layer', and last place means it will be rendered at the bottom, so everything will overdrawn by another elements.
Thank you both!
Yes it doesn't look very clear and pretty. Plus the configuration and order, I have duration steps to high and the line becomes very close the X axis, still it was very helpful for the next configurations!
Thank you!
