How does RGraph work with epoch timestamps? I trying to scatter graph where the X axis is date stamps.

var set1 = [
       [ 1396411199, 10 ],
       [ 1396497599, 11 ],
       [ 1396583999, 12 ],
];

How do I get RGraph to show proper dates?

Hi there,

You set the xmin to the minimum value - eg 951170461, set the xmax to the maximum value - eg 1398844493 and then you scale will effective ly be (in this case) from 2000 - 2014. You can then decide what you want shown on the X axis - could be as many or as few labels as you wish.

There's a demo of a date/time chart here:

view-source:www.rgraph.net/demos/scatter-date-time-values.html

And a note in the docs here about using date/time values instead of numbers for the xmin/xmax values:

www.rgraph.net/docs/scatter.html#date-time-charts

eg:

obj.set('xmin', '2000-01-01 00:00:00');
obj.set('xmax', '2014-01-01 00:00:00');

It seems very static. Can the range and labels on the x-axis not be determined automatically?

Hi there,


The range is calculated from the difference between the min and max - but the labels are given by you.
