Display y-axis label for plots based on nvd3?

[rob-roesler]

Hi,

one question regarding the plot functions using nvd3. How could I display the label of the y-axis? The following simple example only shows the label for the x-axis:

require(rCharts)
tmp <- data.frame(TIME = seq(-5,5,1), VAL = seq(-5,5,1)^2)
p2 <- nPlot(VAL ~ TIME, data = tmp, type = 'lineChart')
p2$params$xAxis = list(axisLabel = "X")
p2$params$yAxis = list(axisLabel = "Y")
p2

The result I'm searching for should be more look like http://nvd3.org/ghpages/line.html

Thanks in advance and btw - very promising package

Thanks for reporting this issue. I will investigate and post back any solutions I come up with. On a quick note, your usage of the API is incorrect. You cannot access the parameters of the rChart object directly. So your code should read:

require(rCharts)
tmp <- data.frame(TIME = seq(-5,5,1), VAL = seq(-5,5,1)^2)
p2 <- nPlot(VAL ~ TIME, data = tmp, type = 'lineChart')
p2$xAxis(axisLabel = "X")
p2$yAxis(axisLabel = "Y")
p2

I am aware that this does not solve the issue, but just wanted to let you know the correct usage.

UPDATE. @timelyportfolio can you take a look at this when you find the time?

Thanks for the fast answer. I'm looking forward to the fixed version.

If you look into it, "Y" is being drawn but at -63 so it falls outside of the bounds of the container. This happens on line 566 of nv.d3.js:

             .attr('y', rotateYLabel ? (-Math.max(margin.left,width) + 12) : -10); //TODO: consider calculating this based on largest tick width... OR at least expose this on chart

I now it is not as clean as we would like but setting a width less than 62 will work, so something like

p2$yAxis(axisLabel = "Y", width = 40)

will work.

Thanks @timelyportfolio . I would have never figured that one out :)
