Thanks, that is exactly what I needed.

I'd lile to show series part of Highcharts.stockChart('container', {...} alternatively based on certain condition met. Namely I would display it only on some timeslots and hide on other. Is there a possibility to do so or do I need to put whole Highchart module object put into if..else conditional b...

Hi is there a way to disable series, for example volume bars upon materializing certain programmatic conditions. I am aware that Highcart code is an object and we cannot use if..then clausule and put series code inside of it, because series is a key in key-value pai inside js object. Actually I coul...

OK I solved this I had to first calculate minimal value from the raw data array sent from the server for displaying. Then I used this minimal value as the yAxis.min value, instead of using first value in the array that was sent. Sometimes chart calculates min value automatically, sometimes not (if t...

Yet the problem now with using yAxis.min parameter is that sometimes it cuts displaying values below 0, which wasn't the case when I was using it without min value set. It happens on both 'spline' and 'areaspline' chart. Here is the printscreen Here it works: https://ibb.co/QNc73yg but here it doesn...

Thanks for your hint Piotr, it works now. Actually it was the yAxis.min parameter that was set automatically on 'spline' chart but for some reason not in 'areaspline' chart. I have used first number to be displayed on the chart for selected time range as the min parameter value. yAxis: [{ // y axis ...

Thanks. I think using yAxis.min value would not help because it wasnt defined in 'spline' chart either, but displaying data in 'spline' works fine, while showing same data in 'areaspline' graph doesn't. So I don't see why would we need to use parameter in 'areaspline' if we don't use same parameter ...

I have two variants for displaying the same data, spline and areaspline version of a chart. While spline shows chart from the lowest to the highest data value for a chosen period which is ok, areaspline shows data from 0 to the maximum data for that period, which makes chart unrealistically flat loo...

I want to separate bars that represent grouped data to be located at the separate section below the chart. Now they are part of the chart and bars represent number of user votes in the grouped timeslots. If number of users that entered price in any timeslot is greater than the value on the chart, li...

Thanks a lot, that was helpful.

Hello I cannot manage to build dark version of the highstock chart with custom background and foreground colors. Something like those shown on the 'Dark Unica' demo versions of charts. https://www.highcharts.com/stock/demo/areaspline/dark-unica There is a code example by Torstein Honsi, but it is un...

Hello I would kindly ask for an advice. I have a 1 year of near realtime and 1 minute data. I would like to know how highchart algo displays large amounts of data. Let's say that I want to fetch 3 month of 1min data that is: 60min * 24hr * 6 month = 259,200 different items. Let's say every item has ...

Hello I cannot set local timezone (Europe/Paris) into xAxis. I tried with setting time > timezoneOffset: .. and setting xAxis: { type: 'datetime', dateTimeLabelFormats: { minTickInterval: 24 * 3600 * 1000, millisecond: '%b %e' } } It displays day and month 9 Jan but yellow popup tooltip displays wei...

Thanks Mateusz for you kind help I have added approximation= 'sum' parameter, however I have a problem. approximation: 'sum' adds values for selected time period like an hour, but next point on the chart which represents new hour isn't added to that former sum, but is displayed as a separate sum for...

Hello my users enter into the db data like +1 and -1 together with timestamp. How to present those data on the line stockchart elegantly so that it shows points as a sum of hour or day data points chronologically. Sometimes users will enter evaluations several times in a minute, sometimes there will...
