Because of its thorough documentation, cross-browser support, and consistent API, it is now easier than ever to add interactive, responsive charts and <a href=\"https:\/\/www.fusioncharts.com\/fusioncharts\">Live charts<\/a>, such as heatmaps, radar, and stock charts, that display real-time data visualizations to your website.\r\n\r\n<!--more-->\r\n<div id=\"ez-toc-container\" class=\"ez-toc-v2_0_71 counter-hierarchy ez-toc-counter ez-toc-grey ez-toc-container-direction\">\n<div class=\"ez-toc-title-container\"><p class=\"ez-toc-title\" style=\"cursor:inherit\">Table of Contents<\/p>\n<\/div><nav><ul class='ez-toc-list ez-toc-list-level-1 ' ><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-1\" href=\"https:\/\/www.fusioncharts.com\/blog\/fusioncharts-free-now-open-source\/#What_Does_This_Mean_for_You\" title=\"What Does This Mean for You?\">What Does This Mean for You?<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-2\" href=\"https:\/\/www.fusioncharts.com\/blog\/fusioncharts-free-now-open-source\/#Why_Choose_Open_Source\" title=\"Why Choose Open Source?\">Why Choose Open Source?<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-3\" href=\"https:\/\/www.fusioncharts.com\/blog\/fusioncharts-free-now-open-source\/#More_Than_Just_Source_Code\" title=\"More Than Just Source Code\">More Than Just Source Code<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-4\" href=\"https:\/\/www.fusioncharts.com\/blog\/fusioncharts-free-now-open-source\/#A_Little_Spark\" title=\"A Little Spark\">A Little Spark<\/a><\/li><\/ul><\/nav><\/div>\n<h2><span class=\"ez-toc-section\" id=\"What_Does_This_Mean_for_You\"><\/span>What Does This Mean for You?<span class=\"ez-toc-section-end\"><\/span><\/h2>\r\nA lot. But in a nutshell, here&#8217;s what you can do with FusionCharts Free:\r\n<ul>\r\n \t<li><span data-preserver-spaces=\"true\">Use it for any purpose, commercial or personal.<\/span><\/li>\r\n \t<li><span data-preserver-spaces=\"true\">Modify its source code to suit your needs.<\/span><\/li>\r\n \t<li><span data-preserver-spaces=\"true\">Share it with your friends and neighbors.<\/span><\/li>\r\n \t<li><span data-preserver-spaces=\"true\">Re-distribute FusionCharts Free, modified, or the way it is, as part of your software or hardware applications.<\/span><\/li>\r\n<\/ul>\r\n<h2><span class=\"ez-toc-section\" id=\"Why_Choose_Open_Source\"><\/span>Why Choose Open Source?<span class=\"ez-toc-section-end\"><\/span><\/h2>\r\nThere is one main reason why we decided to go open-source. It\u2019s a slightly longer explanation, but we would be glad if you stayed with us on this.\r\n\r\nCharting is a very generic product. No, not the Microsoft Office type-generic, but a wide variety of people still uses it. Different people with different technical backgrounds and different requirements. While the BI folk would like the charts to make for a comprehensive reporting experience, the people using them in Facebook applications would like to see striking graphics and cool animations. And then there are the people who use it in networking tools, website analytics, health monitors, surveys, etc.\r\n\r\nWhile we could patiently sit down on a lazy Sunday afternoon and try granting all your wishes, let\u2019s accept it \u2013 YOU know best what you need. Figuring out everything that you need and, more importantly, how you need it will be a pretty long-winded process for us. Also, it would not be too wise to overwhelm new users with thousands of features when a simple animated chart is all they need. And what\u2019s that thing called file size?\r\n\r\nWith FusionCharts Free as open-source, you can take up the source code and keep what you like, throw what you do not, add what you would like. Just do everything to make it perfectly suited to your needs.\r\n<h2><span class=\"ez-toc-section\" id=\"More_Than_Just_Source_Code\"><\/span>More Than Just Source Code<span class=\"ez-toc-section-end\"><\/span><\/h2>\r\n<span data-preserver-spaces=\"true\">Someone famous once famously said, \u201cA project does not become open source simply by publishing its source code.\u201d We couldn\u2019t agree more.<\/span>\r\n\r\n<span data-preserver-spaces=\"true\">While we would be pretty happy if you made FusionCharts Free entirely suited to your requirements, we would be even happier if you could share that with the community.

So how about giving your imagination a tiny little spark, and then you can pump in some more and ignite a fire?\r\n<ul>\r\n \t<li><strong>Bigger anchors on hover:<\/strong> Currently hovering on an anchor in a line chart, the tooltip corresponding to that data point is displayed. Additionally, you could make the anchor bigger and show a vertical line in the background to mark out the hovered data point.\r\n<p class=\"image-center\"><img decoding=\"async\" class=\"asset-image\" title=\"Tooltip on hover\" src=\"https:\/\/www.fusioncharts.com\/blog\/wp-content\/uploads\/gallery\/images\/6a010534c80b99970c0120a5336d67970b-800wi.jpg\" alt=\"Tooltip on hover\" \/><\/p>\r\n<p class=\"image-center\"><img decoding=\"async\" class=\"asset-image\" title=\"Bigger anchor and vertical line on hover\" src=\"https:\/\/www.fusioncharts.com\/blog\/wp-content\/uploads\/gallery\/images\/6a010534c80b99970c0120a5336ebe970b-800wi.jpg\" alt=\"Bigger anchor and vertical line on hover\" \/><\/p>\r\n<p class=\"image-center\"><strong>Possible Customization<\/strong>: Bigger anchors<\/p>\r\n<\/li>\r\n \t<li><strong>Slanted labels:<\/strong> Yes, some names can be pretty long. So how about adding support for slanted labels rather than just the horizontal and vertical labels that are supported now?\r\n<p class=\"image-center\"><img decoding=\"async\" class=\"asset-image\" title=\"2D Column Chart with horizontal data labels\" src=\"https:\/\/www.fusioncharts.com\/blog\/wp-content\/uploads\/gallery\/images\/6a010534c80b99970c0120a5337519970b-800wi.jpg\" alt=\"2D Column Chart with horizontal data labels\" \/><\/p>\r\n<p class=\"image-center\"><strong>Currently supported<\/strong>: Horizontal (and vertical) data labels<\/p>\r\n<p class=\"image-center\"><img decoding=\"async\" class=\"asset-image\" title=\"2D Column Chart with slanted data labels\" src=\"https:\/\/www.fusioncharts.com\/blog\/wp-content\/uploads\/gallery\/images\/6a010534c80b99970c0120a58a4490970c-800wi.jpg\" alt=\"2D Column Chart with slanted data labels\" \/><\/p>\r\n<p class=\"image-center\"><strong>Possible customization<\/strong>: Slanted data labels<\/p>\r\n<\/li>\r\n \t<li><strong>Add new attributes:<\/strong> You could add new attributes, like displaying the company name right at the top of every chart. Or add fade-in or bounce effects to the chart animation, and then provide an option to choose from one of the numerous animation styles.<\/li>\r\n<\/ul>\r\nThe possibilities are endless!\r\n\r\nWhat is the first thing you would like to modify in FusionCharts Free?
