I have some spreadsheet data in two columns that I plotted into a scattergram. The range of the data includes both positive and negative numbers. I’d like the range to be from, say, -0.75 to +0.75, but I’d like the axis tick marks to be on the muliples of 0.1 : 0, 0.1, 0.2, … and …, -0.2, -0.1, 0. But the tick marks always start at the edge of the graph.
So if I use the scale dialog to set the major interval to 0.1, I get tick marks at -0.75, -0.65, …, -0.5, 0.5, 1.5, … The only way I can get the tick marks to be on multiples of 0.1 is to make my range begin at a multiple of 0.1.
How do I get the major interval to start at zero and work outward from there?
