Book Description

Learn how to create your very own rich and intuitive JavaScript data visualizations using jqPlot

In Detail

jqPlot is a charting and plotting plugin for the jQuery framework with numerous chart style options, and is a great tool to build data visualizations. Using jqPlot, you can create bar charts, pie charts, and even stock market charts. It is more than just a plugin for jQuery; you can design, build, and integrate graphs in a far more straightforward manner than popular feature-rich options such as Highcharts.

This book empowers you to create highly-customized charts and graphs that present your data in a visually appealing and analytic manner. Starting with a basic line graph, you'll cover the other standard charts as well as some of the not-so-standard ones. If you want to be leaps and bounds ahead of your colleagues when it comes to developing graphs and charts for your web applications, this book is the answer.
