I'm trying to restrict shown polar chart not to be drawn above the slices labels.
I tried pane.size and it worked with example1
, but when series data changed it didn't work, see example2, any help?
See this example1, slice3 (red color) at the edge
and in example2 same config but different series data, slice3 (red color) not at the edge.
I need to force slice3 in example2 to be at the edge like in example1
enter code here
Sample polar chart
set yAxis.endOnTick=false did the magic, working sample
yAxis: {
endOnTick: false
}

My issue with the Highcharts Stacked Area chart is in how it selects which series to highlight. It SEEMS to highlight the series associated with the nearest point, whereas I would like it to highlight the series the mouse is actually hovering over.
In the image below, the mouse is actually hovering over the area in light blue, but because the nearest point is in the dark blue series, it's highlighting that area.
This causes an issue when you have multiple series stacked with very small and very high values (even zero). The user hovers a series with a large area, but the point it highlights might be associated with a series with no visible area (because it has a zero data point), and it will highlight the point with a tooltip saying something like "Switzerland: 0.00" rather than "Brazil: 9.999.99", even though you're hovering over Brazil
Disable stickyTracking and enable trackByArea options:
plotOptions: {
series: {
...,
stickyTracking: false,
trackByArea: true
}
}

We are using the packed bubble chart but we are using the size AND color to represent the same data dimension (e.g. money each person has)
Functionally, the color is on a gradient from low to high. And now we would like to add in a legend kindof like what you have on a heat map (https://www.highcharts.com/demo/heatmap) where you can see the low color/value with a gradient to the high color/value. Your demo on the heatmap even has a sympathetic highlight between the cell and the legend... that would be cool to bring over. Hell, it would be super cool to even use the legend to filter or refine the circles!
Anyway. The core of the quesiton is, how can we bring that heatmap style legend into the packed bubble chart? Not the bubble size, but representing the color
You need to use color axis. It is a separate module, but it is also build-in in heatmap and map.
Highcharts.chart('container', {
colorAxis: {
...
},
...
});

I opened the basic column chart using Highcharts and now I need to make little customization. I would like to change the color of the plot band that is visible when I place the mouse pointer within one category on X axis. I tried to use the xAxis -> plotBand option, but it only changes the color with specific start and end values. How could I change this color on mouseover?
This is some example, how I would like it to look: https://www.dropbox.com/s/ilxhd99xo8pwn7v/Zrzut%20ekranu%202015-09-05%2020.20.17.png?dl=0
I have to do a line charts with threshold y=5 where y>5 circle color is green y<5 circle color is red and circle y=5 circle color is orange. Using simple threshold i can draw only 2 color in red and green but i can't do the orange one.
{
name: 'Series1',
data: [
{y:2},
{y:6},
{y:5},
{y:6.5},
{y:3},
{y:10}
],
threshold: 4,
negativeColor: "red",
color: "green"
}
How can i do my chart with 3 color circle using threshold? and how can i take color only in circle but grey in line connected circle?
To do what you are asking will require using multiple series, as in this example:
http://jsfiddle.net/jlbriggs/yHn2D/
You can use the linkedTo property to make them all sit under one legend entry.
However, this kind of display inevitably leads to a a cluttered, overly colored, hectic display.
My example, even though the colors are toned down, looks a bit circus-like.
I would be much more inclined to do soemthing like this:
http://jsfiddle.net/jlbriggs/yHn2D/3/
Highlight the target range on the chart, in a subtle manner. When looking at such a chart day after day, watching for data that is outside of the acceptable range, a chart like this will make it very easy to see.
A chart that highlights every singly point, with multiple colors, whether they require attention or not, will drown the important information in visual clutter.
FWIW.
With Highcharts 3.0 it is possible to create charts with type 'bubble', whereas prior to 3.0 it was necessary to use a 'scatter' chart and modify marker size to make bubble charts. The nice thing about the old way is you had complete control over the visible pixel radius of each bubble--the new bubble charts automatically resize the bubbles so they are sized relative to each other. Is there any way to turn off this behavior or set bubble radius manually?
I am having a hard time seeing how a bubble chart, where the bubbles are not sized relative to each other, would be of any use.
You should be able to use the minSize and maxSize options, however, to control them the way that you need to:
bubble: {
minSize:2,
maxSize:50
}
{{edit:
I don't see them in the docs either, actually. But you can see an example here: http://jsfiddle.net/fXzke/13/ use either number as pixel value, or string with percent of chart height
}}
I found that adding an "empty" bubble to the series helps keep the size of all bubbles in the chart relative to each other:
name: '',
data: [{x:0,y:0,z:0}],
showInLegend: false,
color: 'transparent',
enableMouseTracking: false
Here's a sample on JSFiddle: http://jsfiddle.net/9bebT/2/. The legend, color, and mouse tracking variables each help keep the item in the series but otherwise invisible to the user. If you simply remove the empty bubble or set its visibility to "false," the chart doesn't register the empty bubble's z axis (diameter) as the minSize.
