Horizontal Bar Graphs using ES / JS ?

Mel Smith

2/8/2015 8:19:00 PM

Hi:

I'm about to go exploring (i.e. googling) for ES / JS librairies that
provide Horizontal Bar Graph capabilities.

I would hope to acquire a basic package at a reasonable price ( 'free'
would be nice too) that allows me to build graphs using my own limited
knowledge of ES without relying on other dependencies

I haven't used the <canvas>...</canvas> element of HTML5 yet, but am
reading feverishly, and trying out online examples.

Suggestions appreciated.

Thank you.

MDN is a good place for proper learning JavaScript, DOM, and other web
features.

A rudimentary knowledge of canvas and it's a relatively trivial task.

Basically, you'll be drawing filed rectangles whose dimensions
represent the magnitude of the graph.

Hi JJ and Ed:

I've been 'googling', and I've had a look at "Google Charts". The package &
API looks good.and yet it seems quite simple to set up. I'll be trying that
for now -- unless something better comes along.

Thanks for your suggestions.

https://developers.google.com/chart/interactive/docs/galler...
might be a suitable solution for you.

Highcharts is very good, but there are many others (free and opensource):

You might, or might not, find my
<http://www.merlyn.demon.co.uk/js-grp... and/or
<http://www.merlyn.demon.co.uk/js-misc1.... to be of some help.

To actually operate those pages, one must use a local copy. That
discourages over-download. The pages self-disable when loaded from
Merlyn (or a non-Merlyn copy self-enables). They need a copy of
<http://www.merlyn.demon.co.uk/inc-c....

Section js-misc1.htm#BC should show a vertical bar chart when button
"Chart" is activated.
