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

I've got an ECharts chart that has multiple line series and a scatter series that represents events. For the line series, we left the symbol at the default, but for the event scatter series we set the symbol to 'diamond'. These symbols show up on the chart & in the series legend as expected. However, the tooltip always shows a 10 pixel dot for the marker. The color however is picked up from the series (and even from the visualMap config!). My initial assumption had been that the symbol would also be picked up from the series. In our case we wanted to use a function for tooltip.formatter and even in that function we couldn't figure out how to access and swap in the series symbol for the marker. We ended up working around it by just custom styling our own html to plug in for the marker that matched the diamond symbol pretty well.
So the open questions are:
Is there a way to have the tooltip marker pick up the symbol from the series?
If not, is this a bug? I'm happy to put in an issue on the project but I don't want to do that until I understand a bit more.
Here's some code to illustrate what we had to do to get the diamond in there in case it helps the discussion or if others want to leverage this workaround:
formatTooltip(args){
let time = DateTime.fromISO(args[0].data[0], { zone: this.user.timeZone })
let tooltip = `<div><b>${time.toFormat(TOOLTIP_FORMAT)}</b></div>`
args.forEach(({ marker, seriesName, value }) => {
if (seriesName === 'Events'){
let myMarker = `<span style="display:inline-block;margin-right:4px;width:10px;height:10px;background:${value[4]};transform:rotate(45deg);"></span>`
tooltip += `<div>${myMarker} ${value[3] ? value[3]: ''}</div>`
} else {
value = value || [0, 0]
tooltip += `<div>${marker} ${seriesName}: ${value[1]}</div>`
}
})
return tooltip
},
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]
]
}]

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'
}]
}],

I have a bar chart. It has 25 bars all representing a different category. The chart is fine however it only prints out a few of the categories.
I thought by using the line below that it would display all 25 categories that I have specified in x_labels.
set(gca,'XtickL',x_labels);
I also use the method rotateXLabel and rotate the labels 90 degrees so they are not over writing each other. However still only display some of the categories. How can I display all of them?

Found the solution here. Its not quite 100% perfect though as some of my labels are too long so the chart cuts them off. Need to work out how to get round that issue
[pp,h1,h2]=plotyy((1:length(risk_tot)),risk_tot,(1:length(risk_tot)),risk_cont,'bar','stem');
xData = get(h1,'XData');
set(gca,'Xtick',linspace(xData(1),xData(end),length(x_labels(:, 1))));
Is this what you are looking for?:
value is vector with the provided values
label is a cell with the provided strings
bar(value);
set(gca, 'XTick', 1:length(value))
set(gca, 'XTickLabel', label)
grid on
rotateXLabels(gca(), 90)
I have everything going swimmingly on my pie chart and 3D pie charts within MATLAB for a dataset, however, I noticed that even though I have 21 pieces of data for this pie-chart being fed into the pie-chart call, only 17 appear.
PieChartNums = [ Facebook_count, Google_count, YouTube_count, ThePirateBay_count, StackOverflow_count, SourceForge_count, PythonOrg_count, Reddit_count, KUmail_count, Imgur_count, WOWhead_count, BattleNet_count, Gmail_count, Wired_count, Amazon_count, Twitter_count, IMDB_count, SoundCloud_count, LinkedIn_count, APOD_count, PhysOrg_count];
labels = {'Facebook','Google','YouTube','ThePirateBay','StackOverflow', 'SourceForge', 'Python.org', 'Reddit', 'KU-Email', 'Imgur', 'WOWhead', 'BattleNet', 'Gmail', 'Wired', 'Amazon', 'Twitter', 'IMDB', 'SoundCloud', 'LinkedIn', 'APOD', 'PhysOrg'};
pie3(PieChartNums)
legend(labels,'Location','eastoutside','Orientation','vertical')
This goes for the labels and the physical graph itself.
Excuse the poor formatting in terms of the percentage cluster, this is just a rough version. I tried every orientation and even splitting labels between the orientations without any luck.
Quasi-better resolution for Pie Chart -- Imgur Link
Like Daniel said - it appears that there simply isn't any non-negative data for the missing slices. I tried reproducing your problem with the following initialization, yet it resulted in normal-looking chart:
[ Facebook_count, Google_count, YouTube_count, ThePirateBay_count, ...
StackOverflow_count, SourceForge_count, PythonOrg_count, Reddit_count, ...
KUmail_count, Imgur_count, WOWhead_count, BattleNet_count, Gmail_count, ...
Wired_count, Amazon_count, Twitter_count, IMDB_count, SoundCloud_count, ...
LinkedIn_count, APOD_count, PhysOrg_count] = deal(0.04);
In order to verify this hypothesis - could you provide the data you're using for the chart? Do you get any warnings when plotting the chart?
From inside the code of pie.m:
if any(nonpositive)
warning(message('MATLAB:pie:NonPositiveData'));
x(nonpositive) = [];
end
and:
for i=1:length(x)
if x(i)<.01,
txtlabels{i} = '< 1%';
else
txtlabels{i} = sprintf('%d%%',round(x(i)*100));
end
end
You can see that MATLAB doesn't delete valid slices, but only renames them if the data values are small.
