rotated. Sometimes there are multiple versions of a given font and one of them is a bitmapped font.

The solution to this problem is to remove the bitmapped font from the Windows Fonts folder.

This problem frequently afflicts the Symbol font. This is due to the fact that Microsoft ships a

screen font version of Symbol font. You can fix this by removing the screen font. If you find

something like this in your Fonts folder:

Symbol

Symbol 8,10,12,14,18,24

The first is a TrueType font. The second is a screen font. Removing the second fixes the problem.

Another workaround is to use a font size other than 8, 10, 12, 14, 18, 24, such as 9 points.

Log Axes

Igor has three ways of ticking a log axis that are used depending on the range (number of decades) of the axis:

normal, small range and large range. The normal mode is used when the number of decades lies between

about one third to about ten (the exact upper limit depends on the physical size of the axis and the font size).

If the number of decades of range is less than two or greater than five, you can force Igor to use the

small/large range methods by selecting the LogLin checkbox, which may give better results for log axes

with small or very large range.

When you do this, all of the settings of a linear axis are enabled including manual ticking.

Here is a normal log axis with a range of 0.5 to 30:

If we zoom into a range of 1.5 to 4.5 we get this:

But if we then select the LogLin checkbox, we get better results:

When a log axis

is selected...

...Igor sets the number of ticks... ... you can’t use computed manual ticks...

... and the zero line is not available.
