How can I make a chart with dates on the y axis Chart.js

I have a collection of projects, each of which have a completion date. I am trying to display it on a horizontal bar graph such that the label is on the y-axis and the completion date is on the x-axis, as in this image:
Target axis. I am currently using Chart.js
The problem I am encountering is that Chart.js seems to be incapable of interpreting my data as dates - instead it evaluates it (for example, 2017-02-10 is interpreted as 2005). Based on the documentation at chartjs.org/docs/#scales-time-scale, I have tried to use Moment.js to parse my date strings into moments, but it can't render it.
My best guess is that, since it's a horizontal bar graph, my x-axis values are being treated like y-axis values, and the documentation states that the time scale is only supported on the x-axis.
Is there some workaround that would allow me to use dates as the data, so that it looks like this image, but with the axes from the first image? If not, is there another library I could use that does support this? I haven't found any examples of people using time scales on a horizontal graph, so I don't know if other libraries like CanvasJS can do it either.
Goal data, but wrong x-axis
Thanks.

Highcharts: some x-axis labels are disappearing after using setExtremes()

I was developing a solution for another question here on Stack Overflow (see Highcharts : selection) that has some simple slider elements (using input type="range") to change the categories shown in a column chart. Whenever the user changes the range in either slider element, the chart is redrawn using setExtremes().
I noticed that, in some instances, some of the x-axis labels disappeared, even when I moved the sliders back to their original positions. I've tinkered with a number of x-axis settings, including minPadding, startOnTick, and tickInterval, and none of them seem to solve "The Case of the Missing Labels."
The first screenshot below shows the chart when it's first loaded. All of the x-axis labels are present.
The second screenshot below shows the chart when I change one of the sliders. Some of the x-axis labels are now missing. It looks like they're being staggered.
Here's where the plot thickens: if I adjust the sliders to some other values, all of the labels come back:
Here's the fiddle I developed so you can see a live example of this behavior: https://jsfiddle.net/brightmatrix/uvat8u05/
I'm curious to know why this is happening, and what settings I could use to ensure that all x-axis labels are shown, regardless of what values the user chooses in the sliders.
Thank you very much!
Update: The responses from both Max Uppenkamp and Grzegorz Blachliński are valid and helpful solutions. What I also discovered by chance was that explicitly setting the slider values to integers using parseInt() solved this issue as well. It also helps in comparing both values to make sure a user doesn't choose an end date that is earlier than the start date.

This seems to be intended behavior of Highcharts, however inconsistent it may be.
According to this this should be fixed in current versions of Highcharts, but you might as well try this tick formatter solution.
Edit: If the above doesn't work for you, you might be able to solve the issue by rotating your labels:

Replace x axis of highstock dynamic updated chart

I am working on highstock charts for the first time.
The link http://www.highcharts.com/stock/demo/dynamic-update gives me the solution I need.
But I would like to replace the x - axis values (currently date time) with some other values like length measurements. I would also like to change the date time shown in mouse hover in the above chart with the length measurement values.
Could anyone help me find a way out as I don't see any other dynamic chart as far, specific to my requirement.
Thanks in advance.

Dynamic Highcharts with maximum xaxis points

I try to create dynamic highcharts. I use series.addPoint. It works fine but my chart adds points and doesn't move like here - jsfiddle. It can be with 100 points on the screen.
How can I make only 10 points on the screen and hide old points?

http://api.highcharts.com/highcharts#Series
Series.addPoint()'s third argument is a boolean that enables shifting. If your series is not shifting, try setting the third parameter to true.
As for the second part, are you sure you want to "hide" old data? Generally old data should be shifted off the end in a real time graph (which I assume is what you're going for). If you have too many points, you can make your x-axis smaller via Axis.setExtremes(). http://api.highcharts.com/highcharts#Axis

Adding additional information to Highstock point

I am using the Highstock library (not Highcharts) and I'm running into an issue I'm sure can be solved.
I need to add some dynamic information to each point on a series. Highstock has a built in tooltip that displays limited information about a point onHover.
I have tried adding a new property to the point at the time of creation; however, this new property is not available in the tooltip.
What's interesting is this exact functionality is available in the Highcharts library, but I would like to stick with Highstock if at all possible.
Here is a fiddle showing the desired result in Highcharts.
I have started looking around inside the Highstock javascript file looking for a way to expand the properties of the points that actually get added to the series and I have had some limited success.
I have added the property to the block beginning on line 8319 and again on ll320. This does seem to work, but only when the chart is zoomed in... very odd.
Has anyone tried this before, or have some insight on what I may be overlooking?

You can simply add own custom properties, then in tooltip you have access to them via:
this.points[x].point.options.your_property;
See: http://jsfiddle.net/dWDE6/199/
There is only one limitations which you should be aware of: when dataGrouping is affected all points are created as new one, so you don't have access to that custom properties.
