I nead to create graph Highcharts Spiderweb. Is it possible to set different max values for each category?
At the moment all points are settled in one coordinate system. But there are uncoupled values.
In the spiderweb you can have only one yAxis.

I have a chart where two graphs/series have different units. Therefore the y-Axis is different and the extremes are calculated separately from each other.
Is there a way to tell Highcharts to use the same scale, despite the different units, across all graphs/series?
Below is the chart. Relevant y-axis are the ones on the right, as an example. The units are different: "W/m^2" and "kW/kWp", however I want the scale to be the same.
Of course, one way would be a manual approach: in my controller, to go through all the data series and check the overall minimum and maximum value of all data series and then apply the extremes manually via
chart.yAxis[i].setExtremes(min, max)
but I was wondering if Highcharts has any way, like a configuration option, to achieve this.
I didn't find anything in the docs so far.
Thanks.
There is an option to achieve that. You can link one axis to another via linkedTo property.
From API:
linkedTo : Number
Index of another axis that this axis is linked to. When an axis is linked to a master axis, it will take the same extremes as the master, but as assigned by min or max or by setExtremes. It can be used to show additional info, or to ease reading the chart by duplicating the scales.
http://api.highcharts.com/highcharts/yAxis.linkedTo
Example: http://jsfiddle.net/n8tokqru/
yAxis: [{
}, {
linkedTo: 0
}],
I'm using highcharts and trying to add labels to the grid lines of a polar chart, however, I can only add labels to the first axis (which is the y-axis in the cartesian coordinate system).
Polar charts are not well covered (as well as labels on grids) in the highcharts docs. My current approach is placing the labels manually on the correct positions, which will get cumbersome due to dynamic number of categories and sizes of my chart. Additionally, exporting the chart will not support labels anymore.
Background: Let's assume I am selling tickets for clubbing from Monday to Friday (no weekends, bad choice) for the clubs Green, Black, and Blue. Now, I want to know which club performed best on each day, and also how many tickets are sold in total. Therefore, I'd like to apply different scalings to each axis as attached (manually manipulated). I'm currently normalizing the ticket sales for each day to 0…1 which does the job for comparing each single day, but I can't apply the different labels to the axis.
One way might be to add more panes (with startAngle correction) and yAxes with different scales, so dataLabels are showing as in your image.
Example: http://jsfiddle.net/6b9m7Lvb/
Problem - each yAxis can have only a single pane, each series can have only a single yAxis, so there is one scale for a series - no matter what category.
Another way could be to do the same, but have all yAxes linked to each other, so scale is the same for all. Next it is possible to change axis labels and tooltip display, to match your image.
Example: http://jsfiddle.net/6b9m7Lvb/1/
I have a line chart with a limited Y axis (1-5). There are six different lines represented on the chart (3 each from two different users: measuring feeling 1, feeling 2 and feeling 3 from 1-5).
When users enter the same value over time (for instance, ranking feelings 1 and 2 as 5 for several weeks), the two lines completely overlap and you can only see one.
Is there a way I can offset a particular line by say, a couple pixels up and to the right so if there are two different lines representing same values over time, I can see both at once?
Using pointPlacement it is possible to slightly offset each series, so points with the same values do not overlap each other. The tooltip will still work as if points would overlap, so setting shared to true should help.
Example: https://jsfiddle.net/BlackLabel/3mhyojtd/1/
Another option that will allow not shared tooltip would be to use scatter type series with lineWidth set to 2, to imitate line type series.

Is it possible to change the plot line from some specific point. One way around is to create two series and plot them on chart them. But we want to change the plot lines from specific point without using two series.
I want to make a multiple plots with the x-axis aligned so that we can compare two set of data. I want it to look like this

In my case there are some addition requirement that some of the plot are lines and some are bar. So the default scale does not align even if the data range are the same.
I found some good suggestion about "stacking" the charts. It is a little bit complicated but a promising way to try.
https://stackoverflow.com/a/12179023/229075
However I also have other use case that may push the envelop of simple stacking. For example, I'd like to do scatter plot matrix sometime when both x-axis and y-axis have to align like this

Rather than putting many chart in one Highchart, this may requires have many separate charts but have better control in how the axis is layout.
If you want to use one one chart, you can use linkedTo option to connect axis.
If you want more simple charts, you can manage to connect axis using event afterSetExtremes, where you can call setExtremes() for another chart.
