Written by Richard Heyes, RGraph author, on 22nd July 2020
From version 5.25 RGraph will bundle the Moment.js library with it. This library gives
you far greater control over dates and times than the RGraph library provides. It can
be used like this:
new RGraph.Scatter({
id: 'cvs',
data: data,
options: {
tickmarksSize: 10,
xaxisTickmarksCount: 7,
xaxisScaleMin: moment('2020-01-01'),
xaxisScaleMax: moment('2020-01-01').add(1, 'year'),
backgroundGridVlines: false,
marginRight: 100
}
}).draw();
There are many more possibilities than this of course - some complicated and some not. You can read about moment.js and its documentation at the website: https://momentjs.com
