I have just started using pygal in ipython after installing CairoSVG with pip and Cairo with homebrew.
The graphs render but when I hover over them there is no interactivity (displaying the frequency for a single bar on a bar graph for example)?
What do I need to install to achieve the same rollover/hover functionality that can be seen in the Pygal Documentation?
http://www.pygal.org/en/latest/documentation/first_steps.html
For example when you click on a legend item on a graph, the legend item is greyed out and hidden. Clicking the legend item again makes it return. When I create the sample First Steps code in Ipython and click on a legend item it doesn't disappear.
I stumbled across this issue today. It's the result of a slight typo in the pygal config file.
Fortunately it's simple to fix. Open the config.py file in the pygal directory and add http to the kozea github url as follows:
js = Key(
('http://kozea.github.io/pygal.js/2.0.x/pygal-tooltips.min.js',),
list, "Misc", "List of js file",
"It can be any uri from file:///tmp/ext.js to //domain/ext.js",
str)
That should fix it.
I had the same problem, but after checking the code on git, the better solution would be not to change the config.py file, but instead add
force_uri_protocol='https'
as a parameter to your rendering function, e.g.
chart.render_to_file(output_file, force_uri_protocol='https')
