I want to make a pie chart in ChartJS, where each segment is "filled" (with a different color) according to a certain percentage. Say the pie chart displays various categories and their relative sizes (dimension 1), then I want the partial fill of each segment to show, say, the percentage popularity of each category (dimension 2).
See the example below. I've tried to sketch up what I want. Here is a pie chart with 6 "categories" (segments), and where each are "filled" with a percentage. Note that I can not use a normal nested pie chart, as that would only allow a single, same percentage for each segment.
You can achieve this by using the chart.js polar area chart.

Which type of visualisation I need to choose if I want to show relationships between 3 numerical values and turn the horizontal axis into a logarithmic scale? The worksheet data would include grouped sets of values and you wanted to show patterns in large sets of data, for example by showing linear or non-linear trends, clusters, and outliers?
Bubble Chart
Bar Chart
Treemap
Pie Chart
A bubble Chart is the correct option.
Description
Currently, I have 2 stacked column charts:
1. Number of people by country.
I use a stacked column chart to see the number of men and the number of women by country.
2. Number of pets by country.
I use a stacked column chart to see different groups (dogs / cats / other) by country.
Objective
My objective is to merge both to have only one graph.
For example, on Left Vertical axis, the number of people and on the Right Vertical axis, the number of pets.
Both (number of people, the number of pets) have to use the same X axis.
Is it possible to do this with PowerBI ?
Many thanks in advance
There's not a perfect solution to this.
One option would be to take a look at custom visuals like this one:
Clustered Stacked Bar Chart
With the built-in bar charts, you can do something similar if you shape your data right.
For example, if you shape your data like this:
then you can place Country and Type both on the x-axis and drill down to get a visual like this:
There aren't two vertical axes but it's not too far off.
I would like to create a simple chart from 2 or more columns in Power BI.
Here's my data, for each column, a 1 marks an occurrence of an event, null means it did not happen.
I would like to turn this data into a very simple bar graph, showing both these fields' numeric totals (i.e. summing all the 1's). The bars would be shown side by side. I would like it to look exactly like this, only instead of male/female it would show "alcohol occurrences" and "MDMA" occurrences.
Here's my stacked column chart:
And when I try and put the column names on the axes so that they can be properly labeled, I get this:
I can achieve most of what I want using a clustered bar chart, but the problem there is that it won't let me label the axis with the alcohol / MDMA column names:
How can I make a simple, labeled graph, stacking both columns up against each other, showing the numeric sums for each column? Again, I want it to look exactly as the male/female example shown above. Is this even possible? Thank you in advance.
In the above scenario, all the values are considered to be in the same category and that means there is no direct way to do this. There are a couple of workarounds to make it look like the desired output:
To get the gap between the two bars:
You should create a new measure, Measure New = 0
Add this measure in the middle of the two values in the bar chart
This should give you a gap in between the two bars
To get the axis values added:
Create two text boxes with the text "Alcohol" and "MDMA" added
Place these text boxes below the respective bars to make it look like they are the axis values
These workarounds can become quite tedious when you have to do it for a larger number of charts/values. On a lighter note, it baffles me that you can consistently come up with these specific scenarios where you expect the charts to do exactly the opposite of what they are meant for 😉
I developed the few Line charts for BMP280 sensor data in powerbi. This is one of the line chart for displaying the temperature value by time and device id.
But I want same line chart with different Color like this below image, whenever temperature value suddenly changes.
Can you please tell me is it possible to develop the Line chart with multiple colors?
If you're willing to consider a vertical bar chart instead of a line chart, you would be able to create a calculation for each row that determines whether the change is significant, potentially by comparing an aggregate of recent measurements to specific thresholds.
Once you do that, you would use this column's value as a legend for your visualization. So if a row has a value of "Significant Positive Change" (or something like that), the bar or bars showing that change can be red.
Your other alternative is to use an R-based visual, of which there are surely examples of this type of visualization. I'll update this answer if I find one that looks promising.
Instead of tending 1 data series, you can split it into 2 data series e.g. one with normal temperatures and one with high temperatures. Then you can just plot these in different colours. Just make sure that the ranges are same i.e. cannot be 'Auto'.
With Power BI line charts there is a limitation of not being able to add more than one "Values" field when a "Legend" field has been defined.
The feature I need is to simply be able to plot a horizontal line based on a measure I calculate via DAX.
Currently the Analytics tab allows to add constant lines based on max/min/avg of Value but doesn't allow to specify a measure from the data model to plot as horizontal line.
Can someone provide a solution or work around to be able to plot additional horizontal lines on line chart?
The reason you can't put a second measure on your chart when you have a legend defined is because the legend creates multiple colored lines out of a single measure. If there were 2 measures, it would expect to convert both measures into multiple colored lines too, and then you'd have 2 lines that correspond to each legend item. Either the chart would have two lines with the same color, or you'd need 2 colors for the same legend item. Neither of which are very clear.
I don't think that's what you're looking to accomplish with a second measure, though. You're looking to add a reference line on the chart based on the second measure, not split the 2nd measure out by the legend. It's a reasonable request.
If your legend isn't highly dynamic and doesn't have too many items, you can create a measure for each legend item.
Say you have a Sales measure and a Sales Category with 5 items (Cat1-Cat5 for simplicity). Create 5 measures, each filtered to one legend item.
Cat1 Sales:=CALCULATE([Sales],'Your Table Name'[Sales Category]="Cat1")
Cat2 Sales:=CALCULATE([Sales],'Your Table Name'[Sales Category]="Cat2")
....
You can then remove Sales Category from your legend, and remove Sales from your Values. Instead, in Values, place the 5 measures: Cat1 Sales - Cat5 Sales. This will make one line per legend item, so your chart shouldn't look too different. However, now you've done that, you can also drag on a 6th measure as your reference line. It's not the greatest solution but it should work as a stop-gap.
In the format section of your line chart, you can also change the data color for each measure e.g. if you want your reference line black and your measures shades of blue.
There are several ideas in the Power BI ideas forum requesting a reference line based on a measure, and I do recommend adding your voice to them too.
