stringForValue value argument

[seyfeddin]

I wrote my own formatter and mapped every value with a month string. But every time my overridden stringForValue:axis: method is called, value of value argument is incremented by 0.7, not 1.0.

Am I doing something wrong?

0.000000
0.700000
1.400000
2.100000
2.800000
3.500000
-0.700000
0.000000
0.700000
1.400000
2.100000
2.800000
3.500000
4.200000
0.000000
0.700000
1.400000
2.100000
2.800000

Steps on the axis to render are not limited to just 1.0. The user can zoom in or out, and can show different granularity of the grid.
You can limit that by adjusting the granularity property. Look at the demos :-)
