A couple of days ago I needed to generate some charts using Java so I searched for a library which could do it. Take a look at this post, updating pie charts with latest values. But I couldn't display two graph in same time. Soon I found JFree Chart library and downloaded it from here. But I was surprised when I saw the user guide wasn't free! Therefore I decided to write this post and describe how to obtain JFree Chart data from database (I'll use mysql database). There is a classmethod available on from jchart.views import Chart View # Line Chart is a class inheriting from jchart.Chart line_chart = Line Chart() urlpatterns = [ url(r'^charts/line_chart/$', Chart View.from_chart(line_chart), name='line_chart'), ] You can use a custom templatetag inside your Django template to load this chart asynchronously.
If you want to pursue this, do some testing for your own circumstances.For the charts to be rendered inside the browser you will need to include the Chart. There is a method that should be implemented in the chart class that defines which datasets are to be plotted, this method should be called All of these fields map to the same key in the Chart. For instance, if you wanted to create a chart that does not render responsively you would set the responsive class field to false: which can be used to produce correct dictionaries to configure Chart. Most of these methods only serve as a validation step for your input configuration but some can also transform the input configuration.Lets take a look at an example, how would you configure the X-Axis so it wouldn't be displayed: module contains methods for the properties listed below.The JIRA Charting Plugin now integrates with your issue navigator.When viewing search results you can click the 'Chart' option in the issue navigator views to popup an instant chart view.Chartline_chart = Line Chart()urlpatterns = [ url(r'^charts/line_chart/$', Chart View.from_chart(line_chart), name='line_chart'),] You can use a custom templatetag inside your Django template to load this chart asynchronously.The custom tag behaves like the Django url templatetag and any positional or keyword arguments supplied to it are used to resolve the url for the given url name.For the occasional ramble, updates on books, and other assorted things – sign up to J. Well, you can find it here on my website, over on Twitter, Facebook, or Instagram (I’m terrible at remembering to cross-post but I’m getting better, so pick your poison).To do this we need to setup a url endpoint from which to load the chart's data.There is a classmethod available on from jchart.views import Chart View# Line Chart is a class inheriting from jchart.
