Cosine goes from -1 to 1 and so the x-axis should go in the
middle of the graph. Also, I would like to see an arrow on the axis at the end of it, but that doesn't appear to be possible. Another issue is that I have 24 points which go from 0 to 2*pi, but when I set the scale on the x-axis I can't set it to radians so only 6 points get plotted. DOH! Yet another issue is that I don't want little circle markers for each point, but again it seems impossible to turn these off.
This is about the best cosine plot that's easily achievable with Numbers.
Values are calculated in the chart, using
=2
PI()(ROW()-2)/24
and
=COS(B)
The chart type is a scatter chart—the only non-category type available. Data points connected with a Curve and data point symbol set to None.
X axis at y=0 is an overlaid 'line with single arrow' shape.
Max on X axis set (manually) to the value in B26.
Should be easy to reconstruct after perusing the User Guide mentioned in Jerry's post, but I'd still go with his recommendation regarding using Grapher.app for this.
