jqPlot
jqPlot is packaged with all the basic charts, as well as gauges and candlestick. The
software is open source and totally free. jqPlot is based on the jQuery library and
uses the canvas approach for plotting charts. This product has a very similar look
and feel to Flot/Flotr. Additionally, jqPlot supports animations for column and line
charts, but not pie charts, which could be the general issue on canvas approach to
produce fancy implementations. In terms of documentation, it is probably the most
complete, compared to other free software.
amCharts
amCharts offers a full set of charts in both 2D and 3D with other interesting
charts such as radar, bubble, candlestick, and polar. All the charts look pretty and
support animations. amCharts is free for commercial use but a credit label will be
displayed in the upper-left corner of the charts. The only minor drawback is that the
constructor API style seems a bit clumsy. Each attribute assignment has to be done
either by calling a method or as an assignment statement explicitly, but not by the
object specifier's style.
Ext JS 4 Charts
Ext JS is a very popular Ajax application framework developed by Sencha, a pioneer
company specializing in web application development. In Ext JS 4, it comes with the
pure JavaScript charts library unlike its predecessor Ext JS 3, which uses the YUI 2
Flash chart library. As the market trend is moving away from Adobe Flash, Sencha
responds with a home brew charting library. Ext JS 4 covers all the basic 2D charts
plus the gauge and radar charts, and all the charts support animations. The license
is free for open source and noncommercial usage, and a developer license is needed
for commercial development. A great benefit of Ext JS 4 charts is the integration with
the comprehensive set of UI components, for example, for a chart with a storage
framework, displaying/updating both the chart and the table of data with editors is
very simple to do.
YUI 3 Charts
YUI 3 is another popular Ajax application framework under BSD license. YUI 3 has
removed their support for Flash and implemented their own JavaScript charts. The
new version comes with all the basic charts in 2D without any animation's support.
However, the line charts look just above average, and the column and pie charts
look plain and basic. Like Sencha's Ext JS, charts in YUI can be integrated with other
components supplied by the framework.
FusionCharts
FusionCharts is probably one of the most impressive looking and has the most
comprehensive charts out there in the market. Not only does it come with a full-
range variety of interesting 2D charts (radar, dial, map, and candlestick) available
as a separate product, but it also offers fully interactive 3D charts. All the chart
animations are very professionally done. Basically, FusionCharts can be run in two
modes, Flash or JavaScript. For the JavaScript mode, FusionCharts use their own
extended Highcharts library to achieve the same 2D and 3D effect, and look the same
as their Flash version. Although FusionCharts comes with a higher price tag, this is
the only product that has the best looking charts and rotatable 3D charts.
JS Charts
JS Charts offers all the basic charts in both 2D and 3D looks. JS Charts uses the
HTML5 canvas technology to render charts. The bars and lines look good with
animations, however, the presentation of a pie chart is slightly behind and it offers
no animation support. The product is free for noncommercial use and commercial
license is on per domain basis. The constructor API is similar to amCharts done via
method calls.
Flot and Flotr
Flot is an MIT licensed freeware offering 2D charts but without any animation
at the time of writing. It is a canvas-based product built on the jQuery framework.
The software produces nice-looking line charts but not the bar and pie charts
(which require a plugin). Documentation is not very comprehensive and there
are not many update activities within the product. There is also another chart
package, Flotr, which is inspired by the Flot line chart style and is based on the
Prototype framework. Flotr offers all the basic canvas charts with better looking
bar and pie charts, and includes candlestick and radar charts. However, Flotr has
even fewer activities than Flot; both products seem to be heading towards the end
of their lifecycle
Highcharts
Highcharts is built with the JavaScript framework library, it is implemented
in such a way that it doesn't totally rely on one particular framework. Highcharts is
packaged with adapters, to make its interfaces to framework, pluggable.
As a result, Highcharts can be incorporated under MooTools, Prototype, or
jQuery JavaScript frameworks. This empowers users without compromising
their already developed product or allows them to decide on using the framework
which is best suited to their projects. Highcharts uses jQuery as the default
framework implementation, hence it only requires users to load the jQuery library
before Highcharts.
