Log scale and adding extra settings

[zebulon2]

Hi, I would like to be able to graph my X axis with a log scale on a lineChart. nvd3 offers this feature, using: chart.xScale(d3.scale.log());
Is it possble to add this to django-nvd3?

In a more general way, is there a way to pass supplementary settings so that they blend with the automatic building of the <script> in the HTML page? For instance, having in the extra dictionary something of the form:

'supplementary':'chart.forceY([1,1000000]);'

which would add "chart.forceY([1,1000000]);" inside the <script> section?

Thanks.

I answer to myself: I added:
self.jschart += "chart.xScale(d3.scale.log());"
to NVD3Chart.py in python-nvd3 code, and this works quite well! I just need to change the axis ticks formatting to prevent the X axis to be overwhelmed with labels.
I may be able to submit a patch later, but my programming may be a bit rusty and not very high standard.

Can you show us an example with nvd3 ?

Do you mean a screenshot? See below:

This was obtained adding in NVD3Chart.py :
self.jschart += stab(2)+"chart.xScale(d3.scale.log());\n"####
self.jschart += stab(2)+"chart.xAxis.tickValues([0.001, 0.003, 0.01, 0.03, 0.1, 0.3, 1, 3, 10, 30]);\n"####

Now of course this is only a proof-of-concept. I need to add the code correctly and edit both python-nvd3 and django-nvd3.

I also realised this is similar to qdoolaeg request here: areski/python-nvd3#13
He proposes the more generic solution where any attribute/value could be passed to chart. It is nice, because it would allow users to add non yet supported attributes for django-nvd3.

I can fork your repository and provide a pull request then.

I have sent pull requests for python-nvd3 and django-nvd3. Please let me know what you think.

I suppose we can close this one now?
