In the following ZedGraph, there are no major scaler markers in the negative y axis region. Have I missed an important parameter in setting up the graph?

Hi Reg. Logarithmic scales do not allow negative values. Therefore, they are not shown on either axis, since both have logarithmic scales.

Best regards.
Alvaro.

Hi Alvaro,

The vertical scale is set to linear.

I fixed the later time values to -300.

Oh, yes! You're right. I see "E" and think in logs. Please modify this parameter:

Hi Alvaro,

Thanks much!

ZedGraph is necessary for any log scales as far as I can tell. I has more options than I can keep track of. :>D

Thanks again,
