is there a way for chartjs to do conditional formatting for it's line and area fill charts? basically if values are above a certain threshold, turn the line color to red(or another) vs a different color when values are bellow the given threshold. after looking around I found that AmCharts which does exactly that. Problem is I already have so many charts in my project done using chartjs am wondering if there could be a way of doing it in chartjs as well, rather than have AmCharts as additional resource to load.
any help would be appreciated

if you see the image of the chart that i built in powerbi, you will notice that some of the data label points are overlapping making the numbers hard to see?
I did some googling and found lots of people with the issue but no solutions beyond rolling out your own chart in r or python.
I checked every setting on the chart that i could and i was unable to find anything that would resolve the issue.
Has anyone found a way to fix this overlapping?
Is it possible to mark/highlight regions in a superset line chart or would I need to create a custom chart?
I have a chart showing device voltage and I want to highlight where the low/critical/normal voltage range is.
I can sort of hack it by adding annotation lines and increasing the thickness of the lines to 150. This sort of works but falls apart when the y axis range changes.
Any better ideas?
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'.
I'm using Baidu ECharts2 to visualise a dynamic amount of series (up to 100) as a line chart.
The issue I face is the legend overlaps the graph in case if the series are too many.
I spent good 2 hours in searching the documentation and reading, but cannot figure out any way to set the graph position (y/y2 top/height).
It seems the chart consists of different elements (legend, toolbox etc), but none of them seems to be the graph itself.
An example I found showcases a fully responsive way to position pie charts, but this is not applicable in my case:
https://ecomfe.github.io/echarts-examples/public/editor.html?c=doc-example/pie-media
I'd be grateful if someone has more experience with ECharts and can tell me way to move the graph down by y and set a height.
Thank you!
Your best option may be to set the legend type to scroll so it fits on one line.
legends.push({
type: 'scroll',
show: true,
data: myData,
...
});
You may also be able combine Ovilia's and Zain's solutions to move the grid down to leave space for the legend. Unfortunately that would require a way to determine the legend's size before setting the chart's container size.
You can set grid position to make it.
In ECharts 2, you may set grid.y, grid.y2, or grid.height.
In ECharts 3, you may set grid.top, grid.bottom, or grid.height.
Is there a way to display multiple charts on the same image using Google Charts api?
To elaborate:
I have one data series which I want to display as bar chart.
I have another data set which has nothing to do with the first one (well they are correlated but the values are hundred times bigger).
X-axis is for dates.
I want to have second data set displayed as line chart with Y-axis on the left.
I found something similar in "Compound charts" section but as far as I understand markers are calculated based on already displayed data set - and I want to have them independent.
In other words - is it possible to make image like this:
http://chart.apis.google.com/chart?cht=bvg&chm=D,0033FF,1,0,5,1&chs=200x150&chd=t1:30,10,20|60,40,50&chxt=y
but with the line being independent and their values axis being on the right.
I'm sorry I'm not familiar with the terminology - I'm sure there is a name for what I'm trying to achieve.
Thanks!
Only 2 years behind the curve but just to let you know that I have achieved your objective of displaying 2 datasets (one a bar chart, the other a line chart) against 2 different axis scales.
The devil is in the scaling parameter &chds and explicit axis values using &chxr. Essentially, I defined the explicit scales for the x-axis, y-axis and r-axis. and then instructed the scaling parameter to scale each dataset differently.
So for an r dataset between 0 - 10 and a y dataset between 0-2 I would write;
&chds=0,2,0,10 (y then r defined in my axis parameter, i.e. &chxt=y,r)
...and...
&chxr=0,0,2|1,0,10
Let me know if you need more detail!
I've looked into something similar to this before and have used the google chart API a lot. I'm 90% sure the answer is no. Sry :(
Yep it is possible.
Here is an example of two datasets displayed on the same axes. 1 is a bar chart the other is a line graph....
This line - chd=t1:95,1,1,3,10,3,77|95,52,44,24,11,2,1 - allows for the two datasets.
