Tell us what’s happening:
I am struggling to get my spend_chart to pass.
18: “create_spend_chart” should have correct percentages down the left side"
I think I have the graph section correct? with a leading " " to account for alignment between “100|” and " 90|" (two for " 0|") do I need to mess around with .format() and right-alignment instead?
19: “the height of each bar should be rounded down to the nearest 10”
I think I’ve done that too?
20: “each line in create_spend_chart should be the same length”
unsure why this is failing
EDIT: I’ve been looking in the log (F12) and I cannot for the life of me understand why the chart is printing incorrectly, it also seems to be striping the “|” from the hard coded items in the lines - very stuck
