formatting x-axis legend about chartkick

[ankane]

I don't think there's any easy way to do this right now (but I'd like there to be). You would have to hack on the library. Right now, Chartkick uses a continuous axis type in order to plot irregular time intervals, and Google Charts automatically decides the labels. https://developers.google.com/chart/interactive/docs/customizing_axes

I believe the approach taken in "My domain axis type is not string but I still want a discrete domain axis" will solve this issue. I'll try it out when I get a chance but would gladly accept a pull request if you get it working.

@nicholasjstock Can you use the vAxis Object in the Google charting library.?

@StephenOTT thanks for your suggestion. The issue is not just with font size. I have a chart over 24 months with points every week, currently, each and every date displays a value in the '2012-03-03 timestamp" format.
I'd like to be able to control the axis more fully. as @ankane was saying, the aproach is discussed under the "My domain axis type is not string but I still want a discrete domain axis:" section of https://developers.google.com/chart/interactive/docs/customizing_axes#Terminology would work.

Can you post a image of your chart to show the problem?

Here ya go!

Chartkick now has a discrete: true option (finally). Does this take care of the issue?

Cleaning up issues - feel free to reopen if this is still an issue.

Just for reference in case anyone needs it; this is how you can format axis as a passthrough to google charts:

= column_chart formatted, library: {title: "A Title", vAxis:{textStyle:{color:'gray', fontSize:"8pt"}}, hAxis:{textStyle:{color:'green', fontSize:"8pt"}}}, height:'200px'
