How can I change the domain axis values Dynamically in AndroidPlot? - androidplot

Hi my problem is: I am doing an android app where there is a plot that plots data in real time that it reads from the bluetooh, I can add the y-values to the plot dynamically without any problem,but I'd like to change every second also the values of the domain, the plot plots a new data value every second so I'd like that the domain axis updates it's values every second. How can I do this can u please help me??? thanks

Take a look at the solution provided in this question. You should be able to adapt this to your needs by injecting your own logic into the format(...) method.

How to combine different graphs and plot it in only one graph?

My data is include number of cars in each day and each minutes per day. I know how to plot the data only for one sepecific day in August for example. However, I do not know how to plot other month and bring all of them in only one graph.
Can anyone help me?
Here is a small sample of my data
Final Photo: it is what I have achieved, but do not know how to add legend for them and how to change the color or change the shape of graphs
Thanks in advance
You can use the .plot() method if you're using pyplot.

how to plot one graph after another in jupyter notebook

I'm trying to generate plot for each department and security rating, but all get is just one plot with latest values retrieved from dictionary holder:
my code is here:
https://codeshare.io/aYleWY
how to get:
graph
graph
graph
... but not as a subplot?
EDIT:
Corrected the code, and corrected the bug which repeated same data everywhere, but my plots lost Y axis altogether, any idea why?
You may add the statement plt.figure() in the beginning of your last for-loop in order to create a new figure on each iteration. Good luck!

Displaying each and every value on x-axis in Zing chart

I have many values on x-axis and I want all the values to be displayed on the x-axis when I zoom. Is there any way to do it? As every square has no value mentioned at the bottom, so it would get difficult for the person, seeing the graph, to know which date and time that portion belongs to. You can view my graph on alnnovative.com/zing5.php and could give any suggestion too, if you think it is better to implement, in order to achieve the requirement
You'll want to use a combination of the numeric max-items & the boolean items-overlap attributes within your scale-x object to find the best way to display the information to your users. In this demo, I've reconfigured the format of the timestamps, rotated them to allow for more space, and set the previously mentioned attributes like so:
"items-overlap":true,
"max-items":20
I hope this helps! I'm on the ZingChart team as well, so please let me know if you have any other questions.

chart in excel to represent correlation of 3 parameters

Please dont eat me because of this question :)
I have some data in excel and I would like to make a graphical representation of those data. Structure of my data:
persons ID : from 1 to 485 to every person, there is one parameter like average jumping distance and another parameter (like height) and finally there is a class to which every person belongs to (1, 2 or 3).
To assign persons to classes I have used k-means algorithm.
Now I would like to make a graph of this result. How can I do it please in excel (or by using another tool)?
Thank you
I would use a scatter (XY chart with markers and no lines). Plot average jumping distance on one axis, height on the second axis. Then for the classes I would separate all the data into 3 series and use different colors for each series. I would adjust the marker size to see which one works best with the data.
Here is a fast example to give you an idea how to it would look like. Its not as easy as just clicking once to insert the chart from the data though:

Multiple axis line chart in excel

I'm looking for a multiple axis line chart similar to the one in the image below, (which is a javascript chart made by amcharts).
Does excel have an option to draw charts line these? Note there are 3 Y axes, and 3 line charts allowing you to compare data.
Is it possible to get more than 3 data points, each with unique axis on one chart ?
It is possible to get both the primary and secondary axes on one side of the chart by designating the secondary axis for one of the series.
To get the primary axis on the right side with the secondary axis, you need to set to "High" the Axis Labels option in the Format Axis dialog box for the primary axis.
To get the secondary axis on the left side with the primary axis, you need to set to "Low" the Axis Labels option in the Format Axis dialog box for the secondary axis.
I know of no way to get a third set of axis labels on a single chart. You could fake in axis labels & ticks with text boxes and lines, but it would be hard to get everything aligned correctly.
The more feasible route is that suggested by zx8754: Create a second chart, turning off titles, left axes, etc. and lay it over the first chart. See my very crude mockup which hasn't been fine-tuned yet.
The picture you showd in the question is actually a chart made using JavaScript. It is actually very easy to plot multi-axis chart using JavaScript with the help of 3rd party libraries like HighChart.js or D3.js. Here I propose to use the Funfun Excel add-in which allows you to use JavaScript directly in Excel so you could plot chart like you've showed easily in Excel. Here I made an example using Funfun in Excel.
You could see in this chart you have one axis of Rainfall at the left side while two axis of Temperature and Sea-pressure level at the right side. This is also a combination of line chart and bar chart for different datasets. In this example, with the help of the Funfun add-in, I used HighChart.js to plot this chart.
Funfun also has an online editor in which you could test your JavaScript code with you data. You could check the detailed code of this example on the link below.

Edit: The content on the previous link has been changed so I posted a
new link here. The link below is the original link
https://www.funfun.io/1/#/edit/5a55dc978dfd67466879eb24
If you are satisfied with the result you achieved in the online editor, you could easily load the result into you Excel using the URL above. Of couse first you need to insert the Funfun add-in from Insert - My add-ins. Here are some screenshots showing how you could do this.
Disclosure: I'm a developer of Funfun
There is a way of displaying 3 Y axis see here.
Excel supports Secondary Axis, i.e. only 2 Y axis. Other way would be to chart the 3rd one separately, and overlay on top of the main chart.
An alternative is to normalize the data. Below are three sets of data with widely varying ranges. In the top chart you can see the variation in one series clearly, in another not so clearly, and the third not at all.
In the second range, I have adjusted the series names to include the data range, using this formula in cell C15 and copying it to D15:E15
=C2&" ("&MIN(C3:C9)&" to "&MAX(C3:C9)&")"
I have normalized the values in the data range using this formula in C15 and copying it to the entire range C16:E22
=100*(C3-MIN(C$3:C$9))/(MAX(C$3:C$9)-MIN(C$3:C$9))
In the second chart, you can see a pattern: all series have a low in January, rising to a high in March, and dropping to medium-low value in June or July.
You can modify the normalizing formula however you need:
=100*C3/MAX(C$3:C$9)
=C3/MAX(C$3:C$9)
=(C3-AVERAGE(C$3:C$9))/STDEV(C$3:C$9)
etc.
Taking the answer above as guidance;
I made an extra graph for "hours worked by month", then copy/special-pasted it as a 'linked picture' for use under my other graphs. in other words, I copy pasted my existing graphs over the linked picture made from my new graph with the new axis.. And because it is a linked picture it always updates.
Make it easy on yourself though, make sure you copy an existing graph to build your 'picture' graph - then delete the series or change the data source to what you need as an extra axis. That way you won't have to mess around resizing.
The results were not too bad considering what I wanted to achieve; basically a list of incident frequency bar graph, with a performance tread line, and then a solid 'backdrop' of hours worked.
Thanks to the guy above for the idea!
Best and Free ( maybe only) solution for this is google sheets.
i don't know whether it plots as u expected or not but certainly you can draw multiple axes.
