Remove the legend on chartscrollbar on amcharts

So in the picture attached I would like to remove the data in the scrollbar itself. I've poked around in the chart as much as possible. Best I was able to find was to straight up remove all the labels which is not what I want to do.

The labels in the valueScrollbar are a result of setting autoGridCount to true. You either have to remove the autoGridCount setting or set it to false to remove the labels in the scrollbar.

Alter first vertical grid line in nvd3

I want to remove (or make effectively hidden) the first vertical line in the grid for an nvd3 chart. I thought it was a problem with my chart, but after testing it, I realized it seems to be a more general problem.
I tested it by running the line:
d3.selectAll('.tick, .nv-axislabel, .nv-axis text').attr('fill','#999999')
in the console, at the simplest line chart I could find: http://nvd3.org/examples/line.html and it still didn't work! It changes all the lines except the very first vertical line. I'm baffled, I've tried every combination of classes with stroke, fill, opacity, etc - I can either affect the entire svg (with opacity), or nothing. Anyone have any ideas?
EDIT:
I should have specified this originally, I apologize - I do not want to remove the Y axis entirely. I still need the label and the tick marks - I just want to remove that one vertical line (or at least lighten it - it is much darker than the rest of my chart).

Going by your comments:
You don't want to see the " the first vertical line in the grid for an nvd3 chart"
Which is the y axis:
Two ways to achieve that:
Option1
var chart = nv.models.lineChart()
.margin({left: 100}) //Adjust chart margins to give the x-axis some breathing room.
.useInteractiveGuideline(true) //We want nice looking tooltips and a guideline!
.transitionDuration(350) //how fast do you want the lines to transition?
.showLegend(true) //Show the legend, allowing users to turn on/off line series.
.showYAxis(false) //hide the y-axis
.showXAxis(true); //Show the x-axis
Option2:
Since in your example you are going for a CSS option
d3.selectAll('.nv-y').attr('display','none')
I will prefer Option1
EDIT post your clarification, you wish to make the y axis line light you can use:
d3.selectAll('.nv-y path').attr('opacity','0.1')
or if you want to hide it completely
d3.selectAll('.nv-y path').attr('display','none')

One solution is to specify an array of tick values that you want to use for each axis. Use axis.tickValues([values]) to explicitly declare which XAxis ticks you want for your graph. So you could pop .tickValues([1, 2, 3, 5, 8, 13, 21]); into either the chart.xAxis or the chart.yAxis, and ticks would only appear from the corresponding values in the array. In your case, you would want to put it in the chart.xAxis variable. However if you want to have a dynamic chart, explicitly declaring the tick values would pose a problem once the data is updated in the graph. If on the other hand you are using static data, this is a pretty easy fix. I've tested this solution in their live code editor and it seems to do the trick.

Chartjs extended doughnut with text tooltip issue

I am trying to build an extended doughnut in chartjs. I want to display the highest value as percent and its label in the middle. It works fine on load but breaks after an hover event. One a tooltip is being displayed something breaks the first draw event and move the text on the left and i can't figure how to solve this. I made a fiddle to describe this issue :
http://fiddle.jshell.net/3be5zb0v/
Any ideas on how to fix this ?

Working fiddle - http://fiddle.jshell.net/3be5zb0v/1/
Just add this before your fillText
thechart.textAlign = 'start';

Highcharts paint zero axis black

I have a Highchart bar chart with negative values (with the bars then going downwards). Now I would like to paint a black line for y=0 like so: .
I haven't found a trivial way to do this and I would like to avoid directly modifing the SVG or adding a fake line chart or something. Maybe someone knows better way? I've already played around with (minor)tickInterval and (minor)gridLineColor but that wouldn't solve my problem.

you can use plot lines for this like shown in this example http://jsfiddle.net/4rpNU/
yAxis:{
plotLines:{}
}
here is the api reference for it http://api.highcharts.com/highcharts#yAxis.plotLines
Hope this will be useful for you :)

Highcharts problems: variable legend height

I have to set the height & width of the Highcharts placeholder. But the data to be displayed is variable. When the series names(long name) come to much more. The lengend height grows too high and hide the chart.
How could I solve this problem? Hoping to get some help.

I faced the same issue as you have mentioned. I was setting chart height and marginBottom property for the chart. I removed the marginBotton property and its working fine. AS your legend grows, the chart canvas area gets adjusted by itself and the legend does not overlap with the plot area

After your chart loads.. put this in your code..
$('.highcharts-legend').attr('transform', 'translate(50,400)')
But It will still move if you resize the browser...
Ill let you know if I figure it out..

As you can see here the release 2.2.4 introduces legend paging.
You can custom it following the reference.

As you add your series to the chart just stop adding them to the legend after a certain point (eg after 5) with the following option:
showInLegend: false
docs: http://www.highcharts.com/ref/#plotOptions-series
demo: http://jsfiddle.net/7Mmee/14/

see this jfiddle link.this is fiddle and highchart links
http://jsfiddle.net/highcharts/B9L2b/
I think this will solve your problem.
