graph axis scales

[cmgc]

Has anyone found a way of changing the y axis scales on the graphs?  Expecially applies to rainfall which seems to only have increments of 3 mm.  ( and temperature !)

Dear cmgc and WeatherCat customizers,

Has anyone found a way of changing the y axis scales on the graphs? 

Unfortunately, the graphing package that WeatherCat uses automatically adjusts the scales of the y-axis in response to the variations in the data.  There is no way to control the scaling of the y-axis that I know of.

Expecially applies to rainfall which seems to only have increments of 3 mm. 

Do you mean 3 mm or 0.3 mm?  The smallest amount of rainfall that a Davis station can measure is about 0.3 mm (0.25 mm to be exact.)

3 mm  . That is why it was a pain to read the volumes without going tot he data log. . I see now my graph today is in units of 2  !!  So as you say it has automatically adjusted due to todays values . Tks

You can adjust the height of a graph (or gauge). The app then has to adjust the increments to allow the actual max/min values (plus a little) to fit as those values change. If you wanted to have .01 increments for Pressure, for example, you might try setting the height to some very large value; 2,880 pixels? You may still see increments assigned by the app; the labeling on the graph sides could take up too much space with more decimal places! Just remember, "The Dev knows best"!

A gauge, on the other hand, usually allows you to set a max/min value. The app then computes enough values to fill the arc. The increments will vary depending on the max/min values you set.
