Is there a standard way to get dates on the x-axis for Highcharts? When my time range is large enough, it shows dates. However, when the time range isn't large enough, it just shows hours, like this:.

This is less than ideal Anyone know how? Highcharts will automatically try to find the best format for the current zoom-range. This is done if the xAxis has the type 'datetime'. Next the unit of the current zoom is calculated, it could be one of:. These are the available patters:. Check this sample out from the Highcharts API. Look here about the dateFormat function.

Found by reading the source, check the dateFormat method here: Utilities. Just to add to this, the default pattern for the current zoom level also includes the 'millisecond' key.Highcharts is a fantastic library for drawing interactive charts on your website.

I've been using it extensively over the past year or two. There are loads of extensibility points, if you don't like the default behaviour or need to change it slightly to fit your requirements, then it's more than likely Highcharts has you covered. Highcharts provides some very sane defaults, however the more you use it and want to push its boundaries the more you'll have to do yourself. You can follow along and see examples of the below Highcharts configuration in this plunk. Case in point - I've been needing to customise the ToolTips when you hover over a data series.

On taking control from Highcharts, by way of a formatter functionI had lost all the nice currency formatting highcharts provides "out of the box". For example the below before allows me add a GBP Currency symbol before the value and ensure all values are to 2 decimal places.

But doesn't give me much flexibility when I want to properly customise the tooltip. However, for the sake of demonstration say I wanted to customise the tooltip, I want to share the tooltip for all series and add another line of text under the title, some text before and after the actual value.

This is where Highcharts Formatters come in. Simply put its a property which is a function you supply. In that function takes no parameters the this keyword holds various bits of information about the point s which are being hovered. That's good, however if you view the example and un-comment the marked code the code above you'll see how "unformatted" that looks. It wont perform rounding, it wont put in "thousands separators" and we'd have to do the decimal place stuff ourselves.

Now, I know that this functionality exists in Highcharts and I'd prefer not to have to write this again myself. So I went digging through the API documentation and couldn't find a way to get access to the code which does number formatting.

Next step - downloaded the source and started wading through that, it helps if you know where to look - Highcharts is a big, mature and flexible library so there's A LOT of code.

Sign in to your account. When you have defined the xAxis as a 'dateTime' type the tooltip should be aware of this as the 'point.

As you can see the X-Axis is correct in that it uses the Time rage however when you view the default tooltip you get the epoch time. I do agree that I would expect the tooltip to print dates in this case, however it would also require an additional setting for what tooltip format to use, so maybe we would be just as far I don't see any reason to deviate from the standard linechart label when representing dateTime, I can take a look over the weekend and you can see what you think i guess, I have my concerns more-so about when you have multiple X-Axis's for example.

Solution is simple, see: comment - set pointFormat with required formatting for x-value. Alternatively, you can use tooltip. Thanks pawelfus it worked. Hi pawelfus Tried to implement the code and it returned an error 'chart object. Hi bharatnagdev Did you place the code in the section:. When I run the console I do not see the error. Could you confirm that it still appears? If yes, which browser do you use?

Hi sebastianbochan. Another error was Property 'merge' does not exist on type 'Static'. So you are not looking for a Highcharts Cloud solution? In that case please provide full description of the issue.

Additionally, please provide a live demo. Note that solutions for Highcharts Cloud are different from simply using Highcharts library Hi pawelfus i shared the Highcharts cloud link for the explanation of issue i am facing. In your case bharatnagdev simply set headerFormat in options for series or for tooltip, like any other option. Thanks pawelfus finally it worked. Skip to content.Your issue is that the JSON transfer format for your date from.

NET is not easily understood by JavaScript and needs to be converted to an integer timestamp for HighCharts to work with it. You can address this on the server side or the client side, but to do so on the client side you need to either convert the data before sending it to HighCharts or supply HighCharts with a format function to do the conversion.

Here you massage your data before handing it to HighCharts by parsing all of the date strings that. NET gives you into timestamp integers.

This allows for HighCharts to use the timestamps for formatting. This function trims the first part of the string you get from. NET off and converts the timestamp portion to an integer to pass to a Date constructor. You should run this function against each date value in the JSON you receive when it is first received, but before you hand the data to HighCharts for rendering. Here you modify the HighCharts config to supply it with a formatter function on the xAxis that will convert your values at runtime.

This is a bit cleaner of a solution, but you lose the normal ability to format the dates with dateTimeLabelFormats and have to use HighCharts.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

I have an dateline type of graph displayed using both angularjs and highcharts. As i have read in many forums I converted my date to UTC format for plotting in graph. The graph is plotted correctly, but my xaxis is dispalying on they UTC values like 1,G for all the date time values. Feel free to play with the fiddle.

And you might aware that, if you comment out type:"datetime"the xAxis will display the label like 1,G as you mentioned. Also, since the interval of your sample data is one month, the label format of xAxis won't be changed if you configure day format in dateTimeLabelFormats. Instead, you need to configure the month format since the minimum interval is one month. Learn more.

I think the only thing you need to change is the configuration for xAxis. Ethan Wu Ethan Wu 9 9 silver badges 16 16 bronze badges. I tried what you have said. No change at all in my xaxis labels. Hope it can help you. Sign up or log in Sign up using Google. Sign up using Facebook.I trying to use a scatter chart where the x axis is time, and the y axis is a decimal value.

I was able to make a scatter chart appear, and was able to use the y-axis formatting to set min and max values. I can't seem to format the x-axis min and max values.

XAxisFormat doesn't seem to do anything with time values. Did you look at the Highcharts documentation? I couldn't figure out from the Highcharts documentation how to enter time values for x min and x max, at least in a manner that does something useful. However, I hadn't thought to use the generated HTML to see what it is actually picking up from my attempts. That might help me get to the answer. Hi Chuck, you need to provide the x values in milliseconds since 1 January Having done this, you can set a min and a max for the x-axis.

To do this, you need also to provide the min and max as the number of milliseconds since 1 January You can use the XAxisFormat structure for this. It will work :.

I'm sending you an application exemplifying it. You see a line chart containing only two data points even though the serie passed to the graph contains four data points.

The min and the max constraint is working :. Hi Chuck, here is also the extension the application I uploaded depends upon. This extension only works for. Wow, thanks for the generous help. I need to work through this, but it seems like the key part is that your method turns the x labels into a simple number milliseconds wrt 1 Jan instead of a more complex time or date-time. I'll give this a try. Hi Chuck, have you tried it out?

When displaying a series with a single data point using pointIntervalUnitthe x-axis label is incorrectly interpreted.

Series with more than one data point are labeled correctly. If you add a second data point to the series in the jsfiddle, the labels appear correctly. Hi dougbergh. Thank you reporting this issue. In general, when there is only one point it is hard to guess the best format for just one label.

However, I agree with you: when pointIntervalUnit is set, we can use that info to use specific unit for that one label. Or I could fix it myself and submit a PR, right? If I don't do that, do you have a sense of when someone might fix it? I appreciate your attention, thanks a bunch!

TorsteinHonsi what do you think about this issue?

The dateTimeLabelFormat is computed in Tick. It ultimately comes from the normalizeTimeTickInterval function, that lands on 1 ms tick interval because there is no known range.

Honestly I'm not sure how to handle it. We could have a mechanism that when there is only one single tick on the axis, it looks to properties like pointRangepointInterval and pointIntervalUnit on the series. But what if that single point is on an odd time like am like in this case? Should we still just show the date? Hi zelenkoff could you try this workaround?

It's rather simple solution. Apply labels. Hi, pawelfus! Thank you, it's works for me.
