"That said, your decimal places aren't really giving you anything, since 1.00 === 1. There is absolutely no reason to specify them." This is a false assumption and I find the lack of control still available to the developer in this regard a year on from this thread to be very frustrating. I need to display my values to the correct decimal place, even if it is 1.00. If a spec limit is set to two decimal places, then when I create these google charts, I need to display my results to the same decimal place as the spec. Cutting the decimal place short leaves the charts up for scrutiny. If the value displayed is 1 and not 1.00, how does the viewer know I have not incorrectly rounded a value such as, say, 1.01 or 1.41 down to 1? They dont is the answer. That information needs to be made very explicit in some industries. Also, the decimal rounding just does not work. I have values that should be rounding to 3 decimal places. I have values such as 7.413, 7.391 etc that are displaying as 7.4. They are being drawn as 7.413 sure, but the chart tooltip and the y axis on the chart reads 7.4. This is even a bigger issue than the previous example. If someone wants to see how close a result came to a spec limit, they cant get that information from the chart - which sort of defeats the purpose. Now instead of using these web browser based interactive charts, they are having to access the data source itself. Can you see my dilemna? I would like to know if the formatting options for material charts are being looked at in any serious way at google, because this thread is a year old and as far as I can tell, nothing has changed. These details may seem minor, but they can have big implications to the usability of such a library.
