tooltip not showing very smal numbers

[Just Thinking]

Hi,

I have a line chart where the y values are in the order of 0.00001. The line chart works fine, but when I hover over it with the mouse, the tool tip only shows 0. I guess it is rounding the number? Can this be turned off or specified to how many decimal places it will round to?

Thx.

I believe you can apply a formatter before you draw the chart. 

formatter = new google.visualization.NumberFormat({
pattern = "#.#####";
});


formatter.format(yourDataTableorDataViewHere, columnID);

Not sure if it has any digit limitations.

The tooltip display value comes from your data. If the value is only on the order of 0.00001, then it should not be rounding to 0.   You can specify the formatted representation of the values in your data, or by using one of the formatters.  Perhaps you should point us at your chart so we can debug the page.
