Stockchart showing 0 values incorrectly when valueAxis type=log

[Josh]

Hi,

Please see the two charts in this example.

As you can see, the first chart shows the 0 value data points correctly. But, when set to valueAxis: { type: "log" } the 0 values no longer show as 0 values. How can we fix this?

Thanks,
Josh

Hello Josh,

The behavior is expected. The chart will skip non-positive values when using a logarithmic axis because non-positive numbers cannot be the result of raising the base to any power.  A logarithmic axis can be used only for positive values.

Note to others that may have this issue - a workaround is to change 0 values to 0.00001 and then show the correct 0 value in series tooltip.
