Re: Navigator xAxis - start and end "on tick" do not work

Yeah, that's much better solution I think. Anyway, there are still some overlaps of first and last tick with the adjacent ones in some cases. We will probably remove first and last tick calculated by the Highcharts as we are replacing them by our very first and last tick. With this adjusted solution...

Re: Navigator xAxis - start and end "on tick" do not work

Thanks for reply. I get it, you can define your tickPositions array, but we have chart data of variable length. Sometimes 8000 points, sometime 60 points. Also another problem you can check in the demo is when you change size of the chart as a whole - I mean the browser window for example. It will s...

Navigator xAxis - start and end "on tick" do not work

Hi, is it possible to enable label also on the very left and right side of navigator? That means the very first and last tick. Nothing works for us so far. We can use this demo for example: https://jsfiddle.net/gh/get/library/pure/highcharts/highcharts/tree/master/samples/stock/demo/basic-line Thank...

Re: Logarithmic type y-axis with 0 as minimum

It's basically all about that logarithmic y-axis. You can see the problem even in absolutely simple example like here: https://jsfiddle.net/1szmgj8r/ https://i.ibb.co/VjChjnR/image.png The goal is to have y-axis minimum set to 0 and get rid of the exponential notation (that means the letter "e&...

Logarithmic type y-axis with 0 as minimum

Hi. We understand that 0 is not valid as logarithmic axis can never become negative or zero. But it was somehow working good for us in the past until yesterday when we upgraded Highcharts to the newest version 10. In the past: https://i.ibb.co/Fz0ddBW/image.png Now: https://i.ibb.co/zmNg3X4/image.pn...

Display axis plot bands when no series created

Hi,

is there a way to display chart x-axis plot bands when no series are created (series property is equal to empty array)?

Thanks,

[Heatmap] Heatmap values overlap axis labels when scrolling

Hi, https://i.ibb.co/pX1mr7g/image.png Do you have an idea what can be the reason why axis labels are overlapped when scrollbar is moved (exact places are underlined in the image)? It is happening only in one direction - one axis. When we reverse axis, then it is happening on the opposite side. So w...

[Heatmap] Is there a way to set background color for missing coordinates values?

Hi, is there a way to set background color for all missing coordinates in the heatmap? It does not mean "null" values, but really no value in terms of missing completely. For example: [ [0, 0, 3542], [0, 1, 8124], // [0, 2, <value>] is missing [0, 3, 1123], .... ] Right now, it behaves lik...

[Heatmap] How to provide scrollbars when there are a lot of points?

Hi,

is there a possibility to show scrollbars (both vertical and horizontal) when there are a lot of points inside heatmap? That probably means, that we have to define some minimum point width/height, but maybe I am wrong.

Can somebody help us? Thanks a lot!

Re: [Heatmap] First or last series is not displayed if it has no data

Hmm, it's interesting that in your example the behaviour is OK. We use Highcharts API methods like addSeries() to add series etc., so maybe that is the problem. I will try to create an example with our issue.

[Heatmap] First or last series is not displayed if it has no data

Hi all, I could not find a way, how to display empty rows (all values equal to "null") in the heatmap. They are automatically removed if they are first or last series of the heatmap. Example: You can see, that in the heatmap the second series (row) is all empty (all values equal to "n...

[Scatter plot] How to apply color axis to points

Hi all, is is possible to configure color axis in scatter chart? So that points will be defined by x, y and value. X and Y will be represented as position of point inside chart plot of course. This is default behaviour, it is ok. But value should be represented as a color on a scale similarly to hea...

[Heatmap] How to show color axis in legend only for the focused series

Hi, we have a heatmap chart containing several series - each row corresponds to one series, which has one color axis assigned. So for example, our chart can have 20 rows = 20 series = 20 color axes. How we can achieve to show only one color axis of the series, on which user is pointing the cursor at...
