You probably did not set AxisIndexY property.

See documantation (http://wiki.lazarus.freepascal.org/TAChart_documentation#Axis_transformations) and tutorial (http://wiki.lazarus.freepascal.org/TAChart_Tutorial:_ListChartSource,_Logarithmic_Axis,_Fitting) to learn more.

no way to put the values ​​well.
If I put style=smvalue, format changes to "%0:0.9g" automatically.
I need to format "#,##0.##0" or "%4.3n" with smvalue. But do not do it.
I leave it in decimal.
greetings.

-------------------------------------------------------------------
no hay manera de poner los valores bien.
Si pongo style=smvalue, format cambia a "%0:.9g" automáticamente
Necesito poner formato "#,##0.##0" o "%4.3n" con smvalue. Pero no sé hacerlo.(o no se puede).
Lo dejo en decimal.
Un saludo.

First, is your previous problem solved?

Set Marks.Format = '%0:4.3n'.
The Style will automatically change to smsCustom, which is fine.
