      I am not sure I understand what you mean. Consider http://jsfiddle.net/p49ob603/. When you resize that chart (by dragging the splitter in the middle of jsFiddle), the chart resizes, but the text size is constant at its given pixel value.

      Do you mean it should be fixed relative to the chart size? Maybe you want to use a relative font size unit? http://jsfiddle.net/yjrzdpn4/

        Ok, takk for info! Eg er fortsatt ikkje sikker på om det trengst ein option her - for eksempel kan du reversere colors-arrayen ved å gjere colors.reverse() i options-settet ditt.

        AdminTorstein Hønsi (CPO, Founder, Highcharts JS) commented  · 

        I can only advice you on how Highmaps works, not your UI, but I can see two possible ways of dealing with this for you:

        1. Apply the color set dynamically based on how many data classes there are. See http://jsfiddle.net/highcharts/vs9twuLb/ for a proof of concept.

        2. Set the colors directly on the data classes: http://jsfiddle.net/highcharts/vs9twuLb/1/

        AdminTorstein Hønsi (CPO, Founder, Highcharts JS) commented  · 

        I'm not sure what you mean by reversing the selected colorscheme - are you using some kind of GUI on top of Highmaps? Can we see a demo?

        Also, for dataclasses, this is how they currently work. If you have two data classes, the chart uses either one or the other color, with no interpolation in between. A demo of what you're trying to achieve would be nice her too.

          Sorry, it was pointing to my local test server. Try http://jsfiddle.net/highcharts/h24v71vs/.

            Using separate X axes looks promising. Also by setting the colorByPoint option to false you get one color per series: http://jsfiddle.net/highcharts/znm6f89r/120/

            I am not sure how or whether we can align the font sizes between series - my colleague will come back to you about that.

              Highcharts provides APIs for Chart.addAnnotation, Chart.removeAnnotations and Chart.drawAnnotations. You can attach those to user events in your app, and store the annotation items for example in local storage to be added the next time the page is loaded.

              AdminTorstein Hønsi (CPO, Founder, Highcharts JS) commented  · 

              You could for example catch the select event on a point, and when a point is selected, show an input box where the user can add some text. This text is sent by Ajax to the server and stored. In Highcharts, it can be displayed either as a data label, or a flag series item.

              AdminTorstein Hønsi (CPO, Founder, Highcharts JS) commented  · 

              Amit, you're right. We could provide an API and fire events on add, update and delete annotations. Then it would be up to your implementation to hook up to the events, send Ajax calls and relate to the server side storage.

                It's hard to say without seeing your actual code - what I can say is that the point configurations must be objects, then you set that marker configuration on the last of the objects.

                AdminTorstein Hønsi (CPO, Founder, Highcharts JS) commented  · 

                Thanks for using Highcharts!

                > on a lot of our linecharts the point density is so great that the chart becomes unreadable, but not dense enough for the "null" option to kick in and remove the markers.

                Does this mean we could solve your case by adding an option for when to remove the markers? Currently they are removed when the closest distance between two points is less than twice the marker radius, i.e. before markers start overlapping. We could easily add an option to increase the threshold. Then if we add a single marker in the cases when they are auto-removed, it would meet your requirement?

                  Thanks for using Highcharts! You still need the plugin for this. Do you have a case where it's not working as expected?

                  It's not included in Highcharts yet. There are still an issue with how to handle cases when one of the axes' threshold is not in the scale: http://jsfiddle.net/highcharts/gkf9o1vh/.

                  AdminTorstein Hønsi (CPO, Founder, Highcharts JS) commented  · 

                  Bar series per se don't seem to pose a problem: http://jsfiddle.net/highcharts/v44tf7zy/.

                  Also, I have fixed the "Maximum call stack size exceeded" error.

                  @Genís Días this also fixes your case: https://jsfiddle.net/highcharts/8dbfhhkp/3/

                  AdminTorstein Hønsi (CPO, Founder, Highcharts JS) commented  · 

                  Yes, it looks that way from the jsFiddle demo.

                  AdminTorstein Hønsi (CPO, Founder, Highcharts JS) commented  · 

                  @Ronny It will not work with fixed tick positions, because we need to be able to modify the ticks in order to align the axes. Currently it only runs on the second axis. In order to make it run both ways, we need to do some restructuring and make the whole logic recursive, because when the first axis is handled, we don't know the extremes of the second one.

                  AdminTorstein Hønsi (CPO, Founder, Highcharts JS) commented  · 

                  @Lukasz Currently you can't set both, as the alignThreshold plugin overwrites the alignTicks setting. But in general, if you use a smaller tickPixelInterval, the alignment gets better because it is easier to find an axis resolution that fits both data sets: http://jsfiddle.net/highcharts/y6pbqk6q/2/

                  AdminTorstein Hønsi (CPO, Founder, Highcharts JS) commented  · 

                  It's still not perfect, as it disregards the tickPixelInterval setting.

                  For your solution about setting min and max explicitly. The docs explains why Highcharts adds padding to your setting: http://api.highcharts.com/highcharts#yAxis.min

                  AdminTorstein Hønsi (CPO, Founder, Highcharts JS) commented  · 

                  @Luis Miguel: You need to supply a threshold. Lines don't have a threshold by default. http://jsfiddle.net/highcharts/jrXQe/5/

                  AdminTorstein Hønsi (CPO, Founder, Highcharts JS) commented  · 

                  The difference is that line series don't have a threshold by default, so you need to threshold: 0 on the line series. I've fixed this in the plugin so when no threshold is given, 0 is assumed.

                  We appreciate the many votes - I'm afraid the train has left for 3.0, and we will have some catching up to do now before adding new features.

                    That would be a bit like the standard, grouped columns, right? Or do you mean something different? https://www.highcharts.com/demo/column-basic

                    Yes the devs at Black Label are probably happy for that. And you should post the issue at https://github.com/blacklabel/grouped_categories/issues so it is registered.

                      It looks pretty similar to me, see http://jsfiddle.net/gh/get/library/pure/highcharts/highcharts/tree/master/samples/stock/xaxis/crosshair-label/

                      Do you mean that the entire side of the Y axis label should be an arrow?

                        Hi Martin,

                        My coworker added a different approach, that uses the tooltip.formatter to look for nearby points. It would probably work better for your case. See oysteinmoseng's comment on https://github.com/highcharts/highcharts/issues/647.

                        Hi Peter,
                        Currently we don't have plans to do this internally. Is there any specific reason you don't want to do it like in the demo below?

                        AdminTorstein Hønsi (CPO, Founder, Highcharts JS) commented  · 

                        It's not currently supported out of the box, but one way to do it would be to write your own interpolation function and add an interpolated line. I set up a demo here: http://jsfiddle.net/highcharts/F4e2Y/

                          I'm not sure what you mean... Can you elaborate with an example?

                          Here's an empty series. No line is shown: http://jsfiddle.net/vqq6rrtr/

                          An empty chart will render the chart title, credits and stuff that is not related to the data. If that is not desired, you should defer creation of the chart until the data is ready.

                              Do you mean the current configuration? We've got functionality for that in the export module, but it is not cleanly available as an API call. It is part of the getSVG function, but could probably easily be separated out as a function. It is the options that are fed to create the chartCopy.

                                To hide the chart itself you could always use display: none: http://jsfiddle.net/highcharts/VEs7z/4/

                                  Great, I'm happy to hear you figured it out! If you can share it in jsFiddle it would be nice.

                                  Not yet sure I grasp it fully, but maybe we can make it work somehow by using different axes? For example, we can use two y axes and/or two X axes and plot each waterfall series to different places.

                                  Thanks for your suggestion! Do you have a sketch or a screenshot of what you have in mind?

                                    Hi, this feature is prevented in two places, because there were problems with text being selected when trying to zoom in. See https://github.com/highcharts/highcharts/issues/3224.

                                    If you want to enable text selection, there are two lines where the event handling is prevented. If you comment out both these lines, your users can select text:

                                    - https://github.com/highcharts/highcharts/blob/v5.0.14/js/parts/Pointer.js#L756
                                    - https://github.com/highcharts/highcharts/blob/v5.0.14/js/parts/Pointer.js#L813

                                    It works for me. I've updated the links in the status with the correct locations in v5.0.14.

                                        Seems like null, null doesn't work, so you can use xAxis.dataMax:

                                          Hi Michael, I've updated the snippet to a more general approach that looks at the label's actual position. Now it also works with polar. You may want to adjust the exact positions though: http://jsfiddle.net/gh/get/library/pure/highcharts/highcharts/tree/master/samples/highcharts/studies/axis-label-images/

                                          @sahba: It looks like the original fiddle got lost, so I created a new one. Let me know if you have any problems with it, we will keep the snippet updated.

                                          It seems to work when you add a valid CSS width, '150px': http://jsfiddle.net/highcharts/LJbPT/3/

                                            In that case we need to look at the next valid value instead of the last. Here's a modified version of the plugin where we look both up and down and interpolate if both values are present: http://jsfiddle.net/highcharts/FKSZ6/
