What I am trying to achieve is to develop a graph that combines line series with bars. The x axis should be a simple timeline (dates) and the 2 y axes should be linear or logarithmic values. I have no problem creating the line series and the timeline axis.
My problem is when I am trying to implement the "time span bars". It's sort of a gantt chart combined with a line chart I guess. The bars represent data where each bar has a start date, and optionally an end date. I want each bar to start at the start date (aligned with the x axis) and end at the end date if available. If no end date is available, the bar should fill the entire chart until the right edge. I cannot figure out how to combine these time span bars with the line series. I have checked out the jsfiddle /8JhXv/1/ which is pretty close to what I am trying to achieve, except in that example, they are not on top of each other. Anyone who could give me some hints on how to put these on top of each other?
Look at some of the options here:

Best option is not to use actual bars, but to use line series with lineWidth set to a high enough value to mimic bars visually.
You can try to use line series and columnrange (http://www.highcharts.com/demo/columnrange)

I basically want to just combine these two charts:
1) Column range: https://www.highcharts.com/demo/columnrange
2) Basic line: https://www.highcharts.com/demo/line-basic
Is this possible, considering that the first chart has a categorical Y-Axis?
I don't need to use categories, I only want the Y-Axis of the line chart. And the lines would be overlaid on top of the horizontal bars.
So both charts would be using the X-Axis time series, but only the line chart would be using the Y-Axis numbers.
You can link both charts into one but you need to remember, that the columnrange chart is inverted and if you want to display line chart exactly like in this example (https://www.highcharts.com/demo/line-basic), you need to swap x values with y values of line series and both axis should have the same scale.

I am using NVD3 to draw a graph that uses an ordinal scale on the x axis for dates. I also have a "focus graph" under it to highlight a specific region to display. To automatically update the ticks that are displayed, I use the tickValues() property.
I want to have label on specific dates at the top of the graph. My solution for this was to create another x axis, but above the the graph, plot the same data, but with a 0 height, and then use tickValues() to set the position of the labels. However, the labels don't show up on the top axis. Is there a solution or alternative?
I guess using a secondary x axis is fine. I forgot to remove the line setting the domain property for my secondary axis. When I removed that, it scaled just like my primary axis :)
while using the older version of highchart - 2.1.6, if a plot had only one value or a series of same values, it would plot at the middle of the screen as below.
But, ever since i have upgraded the version of the highchart to 4.1.5, the line sticks to the bottom, on the xaxis. like this.
I am looking for the option to set it back to normal but, didn't find it yet. Help me out with this please.
I have tried pointPadding on the series and even maxPadding on the yAxis, but no use.
Here is the fiddle where it is replicated -
http://jsfiddle.net/ka4p4sym/2/
var chart = $('#container').highcharts();
I would set yAxis.minRange option, demo. It won't place line exactly in the middle, but will make some extra space on top and bottom.

I'm using Jqplot and I want to draw two series on my graph.
I want these two series to be drawn as bar chart. I also want the first series to be drawn over the second one in case of there x value are the same.
How can I do it? I've tried to specify the barPadding option to 0 but the two series are drawn side by side.
Thanks for your answer.
I'm not sure I understand what you mean by "first series drawn over the second one". Would a stacked bar chart suit your purposes? Check the third example on this page: http://www.jqplot.com/deploy/dist/examples/barTest.html.
