I was wondering if it would be possible to ignore the sizes of segments in highcharts pyramid. I would like all segments to be of the same size despite the value. The reason is that sometimes differences between values may be quite significant and value of 1 - even being extremely important, becomes invisible when the next value is 500. Also, would like to be able to add a legend if possible. It would be nice to set a minimum size of a segment if not possible to get dynamic sizing disabled.
Thanks for your help!

Yes, you can add additional data according to which the height of the segment will be calculated. Next, use keys option to map the values and show the right one in a tooltip and data label:
tooltip: {
pointFormat: '<span style="color:{point.color}">\u25CF</span> {series.name}: <b>{point.realY}</b><br/>'
},
series: [{
...
keys: ['name', 'realY', 'y'],
dataLabels: {
format: '<b>{point.name}</b> ({point.realY:,.0f})',
...
},
data: [
['Website visits', 15654, 1],
['Downloads', 4064, 1],
['Requested price list', 1987, 1],
['Invoice sent', 976, 1],
['Finalized', 846, 1]
]
}]

For better understanding of this question, let me show a working example in TradingView webpage, on which the following chart shows the combination of Momentum (area chart) + ADX (line chart):
As you can see, there are 2 vertical values, at left side is the ADX which the scale goes usually from 0 to 60(+-), but the right side, it can grow much more.
On my attempt to achieve the same here, the momentum (area chart) has a huge range, and the adx (lineal chart) goes from 0 to 60, so when it tries to fit both values under the same scale, my blue line looks like it's almost zero, in comparison with the area chart values. (Mouse-over the blue line showing that is currently 43)
So I think you get the point, would it be possible to have 2 scales/vAxis for each series of values?
I checked documentation already but nothing here seems to refer to what I mention:
https://developers.google.com/chart/interactive/docs/gallery/combochart
And just in case you need the options provided to the chart, nothing advanced, just the basic examples:
options:{
seriesType: 'area',
series: {
0: { type: 'line', color: 'blue' }
}
};
use option --> targetAxisIndex -- in the series option...
zero is the default v-axis
targetAxisIndex: 0
to create a second v-axis, assign one of the series to index 1
series: {
1: {
targetAxisIndex: 1
}
}
Found the solution over this post in the documentation, it is conceptually known as DUAL-Y Charts
https://developers.google.com/chart/interactive/docs/gallery/columnchart#dual-y-charts
I tried reverse=true in the yAxes settings but that does not seem to make a difference.
It always assumes that the min < max in the ticks settings.
Is this possible?
reverse=True does not work in 2.x
I was able to say:
yAxes: [
{
id: 'y1',
type: 'category',
display: true,
labels: ['-3', '-1', '+1', '+3'],
position: 'right',
}
]
to explicitly set the labels in decreasing order. The values continue ro be specified in the original scale so the plot appears correctly.
I also had to override the tooltip callback so that it would show the correct value on hover.
I am trying to offset symbols of a symbol layer so that they don't interfere with a previous symbol layer (i.e. they don't overlap). I need to offset them as in both cases icon-allow-overlap needs to be set to true, as the symbols need to be viewable at all zoom levels. Ideally I'd like to do something like this:
"icon-offset": [
["zoom"],
12, [-16, 0],
22, [0, 0]
]
but that gives me an error:
array length 2 expected, length 5 found
Is there a way I can do what I want similar to what I was trying above? I know that icon-offset is not transitionable so that is why the above is failing.
Any help would be appreciated.
Thanks for your time.
The answer was to use a function:
"icon-offset": {
"stops": [
[12, [-16, 0]],
[22, [0, 0]]
]
}

I'm using Baidu's echarts library
How can I split colors of the area under a line chart after a certain threshold (beyond x-axis) using the areastyle?
Thank you!
You can't.
The areastyle is applied to the series itself, and cannot be tied to individual datapoints. Because the area color actually marks the area between two datapoints.
But.., you can, however, create a workaround and create two linecharts, like so:
legend: {
data: ['myLine']
},
series : [
{
name: 'myLine',
type: 'line',
areaStyle: {
normal: {
color: 'red'
}
},
data: [400, 300, 101, 134, null, null, null]
},
{
name: 'myLine',
type: 'line',
areaStyle: {
normal: {
color: 'green'
}
},
data: [null, null, null, 134, 90, 230, 210]
},
]
By adding it manually to the legend, and by giving both series the same name. ECharts combines the two series to some degree, so both the legend and the animation are acting like it's a single series.
Also, make sure to connect the two lines, by adding a datapoint twice (see 134). And you can customize the lines a little more with lineStyle, etc, to make them look better.
You can create a little demo by checking the ECharts demo gallery and replace the series and legend data with the snippet above (you may have to click the blue run button).
I have a strange behavior with my drill down to a waterfall chart. My middle column which is a negative value is not positioned on the top, instead it is going from zero down.
I have taken the exact same configuration and applied it to a first level waterfall chart and there it works fine.
Expected result: Column 'Discount' should go from 50 to 40
Actual result: Column 'Discount' goes from 0 to -10
JSfiddle for drilldown chart where waterfall is not as I want it:
[Drilldown][1]
JSfiddle for chart where waterfall is correct:
[Waterfall][2]
I can not figure out what is missing.

Based on the Highcharts example of Drilldown from column to pie, you need to set the chart type to be the drilled down type, i.e. to 'waterfall', and set the type of the top level series explicitly, i.e. to 'column'.
Updated chart options with type:
chart: {
type: 'waterfall',
height: 350,
zoomType: 'xy'
},
Updated top level series options with type:
series: [{
type: 'column',
data: [
{
name: 'Sweden',
y: 55,
drilldown: 'Sweden'
}]
}],
