I have a chart which shows the value of a number that is large, but has small fluctuations. For example, it will be 200,000 at minimum and 202,000 at maximum. The issue I am having is that with the axis starting at zero, it is nearly impossible to see the changes on a chart. Is there any way to change the minimum of the Y axis to be say, 80% of the lowest point on a chart? I can't manually set the axis to a number because the data I am throwing in the chart changes dramatically, but still only has small fluctuations (for example 30,000 to 31,000).
