Displaying labels for grouped datasets in ChartJS clustered column graph - chart.js

Not sure how to even define this question, so bear with me!
First, I want to display multiple unrelated datasets, side by side.
Second, for each dataset, I'd like to have column-based lables (default for each column), then an overall "grouped" label for the dataset.
I can "fake" the appearance of this chart by entering a "zero" column entry, creating the gap between the "datasets" I have (even though in ChartJS is just one dataset).
The text line one is default behaviour with ChartJS to display the column label. However getting a "grouped" label to appear is beating me! What I've ended up doing is generating the chart label-less, then doing some funky HTML hacks to get the labels back with the grouped text I need. This approach is not scalable.
Can anyone point me in the right direction for this? Doesn't have to be ChartJS powered.

PowerBI, Conditional Formatting for Stacked Column Chart

I'm a geologist and trying to create a "Stratigraphic Column" to visualize the progress of Drilling Rig and I realized that Stacked Column Chart is suitable for that visualization.
Everything is perfect expect colors. Every lithology has their own color but PowerBI assign random colros to them. There is no any "Conditional Formatting" button in chart properties. That project is very critical for me, is there any code for that or is there any other tool to create something like Stratigraphic Column in PowerBI?
Thats what I want to create similar;
This is my final progress in PowerBI;
This is databse where I get data for chart;
Check if "Sankey Chart" helps.
As I see, there is a Source and Destination.

Why can't I sort this PowerBI chart?

I have charts I want to sort descending. I've read there's a "more options" option if you click on the chart, which should give you ability to sort.
In chart below, there is no sorting option:
Here is the field the chart is based on (it's a single field):
And here's the way I set up the chart:
I click 'more options' and yet see no option to sort. Who knew such a simple task could be that difficult in PowerBI.
My best guess at this point is that you are using two different fields for Male and Female numbers. If this is the case, you won't get the sorting option since the values are coming from two different fields. If you simply want to interchange the position, you can do so in the values section. If this is not the case, please provide further details, so that we can look into it further.
Edit:
I don't think there is a sorting option without having a value in Axis. However, you can adjust the Inner Padding of the Y-axis (in the formatting pane), to get the visual you are looking for. Setting inner padding to 0% will remove all the gap between the two bars. Also, you can do the sorting now, since there is a value in the Axis box.
Note: If you want different colors, add the field in legend as well.
You are using a clustered bar chart. The columns are arranged alphabetically and can't be changed.
If you want to sort the bars by their values, use a regular stacked bar chart and put the "demo_female" in the Axis, not the Legend.

How to create custom legends in Power bi?

I just need to move my legends in top left corner. But there is no option for that.
So is any way I can create maybe a table with one column color shape and the other column the description?
Something like that:
And then just use it as Legends for the chart?
Depending on your visual you have under the format tab a legend option. For example if you use a pie chart you can toggle the legend on or off. Also you can position the legend (top, top left, bottom, etc...).
The second way is to use a custom visual with your desired needs.
And the third way is, like you already stated, a table which acts as legend. Either you enter your legend text in a separate table manually or you use a query. For example a distinct count to get the unique values.

chart.js 2 - Is it possible to format tick labels with HTML?

I have a chart that shows 3 datasets - 2 Line, 1 Bar.
I would like to be able to format the Y-2 axis labels in the screenshot below with HTML to allow me to show the values in each tick as bubbles to match the styling displayed on the line data points. (I am using the datalabels plugin to achieve the data point styling https://github.com/chartjs/chartjs-plugin-datalabels).
In addition to this I would like to have all labels with "XLabelLine1" and "XLabelLine2" to have a line break between them.
Is this possible? From looking at the docs it looks as if the axis labels can only be strings.
You are correct that the tick labels can only be strings and that the Chart.JS tick labels do not have HTML support. It's likely a plugin would need to be developed for this behavior. Sorry. :)

It is possible to hide part of labels google chart

I want to hide couple labels, first 2 and last 2 in axis X.
I want to disable black line at the bottom of the graph.
I'm able to do it after the chart is loaded - using javascript and change it dynamically. When I add new data and use draw method, Graph is overwriting my dynamic stylesheets changes. I was trying to set it as an option in graph initializer but I couldn't find the solution for that.
I use areaChart.
It was 3 years ago. I don't need it anymore. I'm leaving this question for others.
It's a little hard understanding what you're trying to do, but I think I get it.
As I read it, you want to eliminate two variables from your DataTable when you plot your chart (to prevent them from being in the legend)? Assuming that's the case, you can either take them out of the data table, or use a ChartWrapper on your object, and set the view:{columns:[x,y,z]} option to the ChartWrapper. Assuming you can't change the DataTable, or a ChartWrapper isn't an option, and you just want to not have certain plotted objects appear in your chart but not in the legend, you want to set the series option. For example, assuming three columns in your DataTable, you can hide the third item as:
series: [{visibleInLegend:true}, {visibleInLegend:true}, {visibleInLegend:false}],
Second of all, if you want to hide the horizontal axis, you need to have continuous data, and set hAxis.baselineColor to 'clear'.
To hide some of the tick-mark labels, use ticks: ticklist to label the axis, and for some of the labels in ticklist use an {v:value,f:label} structure definition, with a zero-length string for the label.
Here's an example. Note the omitted labels for some of the ticks on each vertical axis. View source to see how I did it:
http://www.sealevel.info/co2_and_ch4c.html
Note the tick list definitions. This one is for the left vertical axis:
var vticklist1 = [{v:235,f:''},{v:250,f:''},275,300,325,350,375,400,{v:425,f:'ppmv'}];
The first & second ticks (at the bottom, for values 235 and 250) display no labels. The next six ticks, for values 275-400, display normally. The last (top) tick displays as "ppmv" instead of 425. The result looks like this:
