I have a few charts that graph some amount (counts, revenue, etc.) over the hour of the day. On some charts the 0 hour appears flush with the y-axis while on others the first real data point is off the y-axis and there's a line from the origin to that first data point. It makes it look like there's a data point at (-1, 0)
Here's a really bad ASCII drawing showing the problem:
5| This data point should be on the y-axis
| |
4| v -+--+-
| +--+/ \
3| / +--...
| |
2| | <-- This squiggly line should be gone
|/
1||
|/
0+--------------------
0 1 2 3 4 ...
^
|
This marker should also be on the y-axis, at the origin
This is how I want it to look:
5|
|
4| -+--+-
+--+/ \
3| +--...
|
2|
|
1|
|
0+-----------------
0 1 2 3 4 ...
As I said, some charts work correctly, but I cannot see a pattern. The only difference is the y-axis values.
