Allow tilting of X-Axis labels to maximize granularity while displaying long labels

[doriancransac]

I'm trying to display date formats such as "yyyy-MM-dd HH:mm:ss" and currently, the fact that the labels are displayed horizontally greatly limits the total number of labels that can be printed along the X Axis.

I would like to be able to provide an angle to which the labels get tilted (between 0 and 360°). To maximize space, a 90° or 180° angle could then be used.

PS: I just noticed I can't seem to find a way to define the number of gradations on the X-Axis either (i.e some sort of granularity that defines the number and length of each interval). That seems like it would be a good combination with the feature I'm asking here, if it doesn't already exist.

These are both features I've always wanted to implement. I may be able to get to it in the next couple of weeks. If you think you can and want to implement, I'd be happy to accept a pull request for one or both of the features...

I went ahead and implemented the second request. See screeny below.

Hi Tim,

Thanks for the quick feedback and update on the second suggestion.

Not sure if I'll be able to get into the code this time around, but I'll definitely keep it in mind and will attempt to implement it when I get a chance.

Regards,

Dorian
