Is it possible to create simple chart using wxFreeChart with Y-axis labelled with double values and X-axis labelled with string values? Which type of chart and dataset should I use? I tried to use XYDynamicSerie and I like it, but it can mess with pair double-double.
I'm an author of wxFreeChart.
Charts, where one axis has string values use CategoryDataset.
Line charts, with CategoryDataset are not supported. Only bar charts (BarPlot).

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 am new to PowerBI so sorry in advance. I would like to reproduce the plot below (created in Tableau) in PowerBI.
I need the two plots to be sorted by the values of the first one.
In PowerBI I can generate two such plots, but I do not manage to use the values of the first plot to sort the second one.
How can I do that?
Plot with an x-axis that is shared by two bar chart plots
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'.
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.

I would like to display multiple colors (and potentially shapes and sizes) of data points in a Google Chart scatter chart. Does anyone have an example of how to do so?
I answered my own question after waiting SECONDS for an answer here :-)
You can indeed have different colors for different data elements. For example:
http://chart.apis.google.com/chart?chs=300x200&cht=s&chd=t:1,2,3|6,5,4&chds=1,3,0,10&chxt=x,y&chxl=0:|0|1|2|1:|0|10&chm=d,ff0000,0,0,8,0|a,ff8080,0,1,42,0|c,ffff00,0,2,16,0
It's the chm= that does the magic. I was trying to have multiple chm= statements. You need to have just one, but with multiple descriptions separated by vertical bars.
You can only use one dataset in a scatter plot, thus only one color.
http://code.google.com/apis/chart/#scatter_plot
From the API description:
Scatter plots use multiple data sets differently than other chart types. You can only show one data set in a scatter plot.
You could effectively fake a multi-color scatter plot by using a line plot with white lines and colored shape markers at the points you want to display.
Here's another example: twitter charts. I'm hoping to do the same thing. Need to find out how to do the concentric circles.
