Re: [TurboGears] Re: Linecharts and TG2

Pandas is a data transformation and analysis library, you can use it with TG without much problems.

I have been using pandas and scikit-learn with TG projects in the past, so you can freely mix them.

On the iPython part, I don't what you intend as iPython is actually an alternative python shell, so it's not much related to web development.

Do the Pandas and iPython frameworks work hand in hand with TG2 and ToscaWidgets... or are these separate frameworks?

Sorry, missed the charts part.

In the past I have been using http://c3js.org/ and https://developers.google.com/chart/ and mixed them with http://www.ractivejs.org/ to provide data-binding for the charts. They are strictly JS libraries, so it doesn't really matter which framework you use.

You can off course use them as TW2 widgets if that helps you (just put the chart code as the template parameter of a widget and you are ready to go), I know there are widgets for plotting already done for TW2 around ( like https://github.com/toscawidgets/tw2.jqplugins.jqplot ) but never tried them.

What's the preferred interface with creating line charts with TG2?  Is it ToscaWidgets?

I'm using ToscaWidgets. Initially I was using the jqplot that Alessandro mentioned but I found them a bit limiting and they didn't fit with the look I was going for.

Alessandro is right, find the JS library that you think will do what you want for starters. I'm using chart.js but there are plenty out there. The next thing is, you got your data in python you know how you want to do your chart in JS, how to get the data to the chart?

For that I use the Toscawidgets core. It's basically something that ensures the relevant javascript and CSS are loaded and I have a html template with the values plugged into it. I like having the python object because I have a generic pie chart object, but then have a new class for status pie (think of red,yellow,green status lights) which inherits the generic one but has different colours.
